Field of invention The present invention relates to substantially pure 2- (5- (4- (2-morpholinoethoxy) phenyl) pyridin-2-yl) -N-benzylacetamide (KX2-391), as well as its mesylates and bis-. Concers with compositions and methods for the synthesis of hydrochlorides. The present invention also relates to a method of using such a composition.
Background of the invention Signal transduction is any process by which a cell converts one type of signal or stimulus into another. A process called signal transduction often involves a series of biochemical reactions inside the cell, which are carried out by enzymes and are related via a second messenger. In many transmission processes, increasing numbers of enzymes and other molecules become involved in events that progress from initial stimulation. In such cases, the chain of processes is referred to as the "signal transduction cascade" or "second messenger pathway" and often results in small stimuli that elicit a large response. A type of molecule involved in signal transduction is the kinase enzyme family. The largest group of kinases is protein kinases, which act on and alter the activity of specific proteins. It is widely used to transmit signals and to control complex intracellular processes.
Protein kinases are one of the larger enzyme types that catalyze the transfer of γ-phosphate of ATP to hydroxyl groups on the side chains of Ser / Thr or Tyr in proteins and peptides, and various important cells. Function, perhaps most notably: is closely involved in the regulation of signal transduction, differentiation, and proliferation. It is estimated that there are about 2,000 different protein kinases in the human body, each of which phosphorylates a particular protein / peptide substrate, but all are highly conserved of the same second substrate, ATP. Combine in the pocket. Protein phosphatase catalyzes the transfer of phosphate in the opposite direction.
Tyrosine kinases are enzymes that can convert the phosphate group of ATP to tyrosine residues in proteins. Protein phosphorylation by kinases is an important mechanism in signal transduction to regulate enzyme activity. Tyrosine kinases are divided into two groups; cytoplasmic proteins and transmembrane receptor-bound kinases. In humans, there are 32 types of cytoplasmic protein tyrosine kinases and 58 types of receptor-bound protein tyrosine kinases. Hormones and growth factors that act on cell surface tyrosine kinase binding receptors are generally growth-promoting and serve to stimulate cell division (eg, insulin, insulin-like growth factor 1, epidermal growth factor).
Various known protein kinase or protein phosphatase inhibitors have a variety of therapeutic applications. An example of a possible promising therapeutic use of a protein kinase or protein phosphatase inhibitor is its use as an anti-cancer agent. Approximately 50% of the known proto-oncogene products are protein tyrosine kinases (PTKs), the kinase activity of which has been shown to result in cellular transformation.
PTKs can be divided into two categories: membrane-receptor-type PTKs (eg, growth factor-receptor-type PTKs) and non-receptor-type PTKs (eg, the Src family of proto-oncogene products). There are at least 9 members in the Src family of non-receptor Tyrosine, pp60<sup>c-src</sup>(Hereinafter, simply referred to as "Src" in the present specification) is a basic form of PTK of the family, which is highly conserved with about 300 catalytic domains of amino acids. Overactivation of Src has been reported in several human cancers, such as colon, breast, lung, bladder, and skin cancers, as well as gastric cancer, hairy cell leukemia, and neuroblastoma. Also, hyperstimulated cell proliferation signals from transmembrane receptors (eg, EGFR and pl85HER2 / Neu) into the cell appear to pass through Src. As a result, Src has recently been proposed to be a universal target for cancer treatment because overactivation (no mutation) is involved in tumor origin, progression and metastasis in many important human tumor types. ing.
Kinases play a role in a variety of diseases and disorders because they are involved in the regulation of a wide variety of normal intracellular signaling pathways (eg, cell growth, differentiation, survival, adhesion, migration, etc.). It is believed that there is. Therefore, modulation of the kinase signaling cascade can be an important method for treating or preventing such diseases and disorders.
Recently, a small-scale synthesis of KX2-391 has been published (Patent Document 1). This synthesis is impractical for mass production of the compound and has the disadvantage that the resulting product is contaminated with ethyl chloride, which is known to be a weak alkylating agent. Therefore, the presence of sufficiently high levels of ethyl chloride limits the pharmaceutical efficacy of the KX2-391 composition.
Therefore, there is a need for an improved synthetic pathway for KX2-391 that is easy to commercialize, safe and easy, and that gives KX2-391 and its salts in large scale, high yield and substantially pure.

how to use Kinases play a role in a variety of diseases and disorders because they are involved in the regulation of a wide variety of normal intracellular signaling pathways (eg, cell growth, differentiation, survival, adhesion, migration, etc.). It is believed that there is. Therefore, modulation of the kinase signaling cascade can be an important method for treating or preventing such diseases and disorders. Such diseases and disorders include, for example, cancer, osteoporosis, cardiovascular disorders, immune system dysfunction, type II diabetes, obesity, and graft rejection.
The compounds of the present invention are useful for modulating the components of the kinase signaling cascade. Some compounds may be useful in modulating more than one component of the kinase signaling cascade. The phrase "regulates one or more components of a protein kinase signaling cascade" means that one or more components of a kinase signaling cascade are affected to alter cell functioning. Components of the protein kinase signaling cascade include any protein directly or indirectly involved in the kinase signaling pathway, such as a second messenger and upstream and downstream targets.
Several protein kinases and phosphatases are known and are targets for the development of therapeutic agents. For example, Hidaka and Kobayashi, Annu.Rev.Pharmacol.Toxicol, 1992, 32: 377-397; Davies et al., Biochem.J., 2000, 351: 95-105, respectively, cited herein by reference. See (embedded).
One of the kinase families, protein tyrosine kinases are two major families: receptor tyrosine kinases, or RTKs (eg, insulin receptor kinase (ERK), epidermal growth factor receptor (EGFR), basic fibroblast growth). Factor receptor (FGFR), platelet-derived growth factor receptor (PDGFR), vascular endothelial growth factor receptor (VEGFR-2 or Flk1 / KDR), and nerve growth factor receptor (NGFR)) and non-receptor tyrosine kinase , Or NRTK (eg, Src family (eg Src, Fyn, Yes, Blk, Yrk, Fgr, Hck, Lck, and Lyn), Fak, Jak, Abl and Zap70). For example, Parang and Sun, Expert See Opin.Ther.Patents, 2005, 15: 1183-1207 (incorporated herein by reference).
Due to the role of Src kinases in various cancers, these kinases are the subject of several studies on the development of Src inhibitors as cancer therapeutics, such as the growth of highly metastatic cancer cells. Src inhibitors are being sought as therapeutic agents for various cancers such as colon cancer, precancerous colon lesions, ovarian cancer, breast cancer, epithelial cancer, esophageal cancer, non-small cell lung cancer, pancreatic cancer and the like. See, for example, Frame, Biochim.Biophys.Acta, 2002, 1602: 114-130 and Parang and Sun, Expert Opin.Ther.Patents, 2005, 15: 1183-1207.
Inhibition of other kinases may be useful in the treatment and modulation of other types of diseases and disorders. For example, various eye diseases can be suppressed or prevented by administration of VEGF receptor tyrosine kinase inhibitors. Inhibitors of the tyrosine phosphatase PTP-1B and / or glycogen phosphorylase may result in treatment for type II diabetes or obesity. Inhibitors of p561ck may be useful in the treatment of immune system disorders. Other targets include HIV reverse transcriptase, thromboxane synthase, EGFRTK, p55 fyn and the like.
The compounds of the invention can be Src signaling inhibitors that bind within the Src peptide substrate site. The activity of the various compounds of the invention was tested in c-Src (527F, constitutively active and transformable) transformed NIH3T3 cells and human colon cancer cells (HT29). For example, in these cell lines, KX2-391 has been shown to reduce phosphorylation levels of known Src protein substrates in a volume-dependent manner, in a volume-dependent manner, in a good correlation with growth inhibitory effects. Thus, in some embodiments, the compounds of the invention can directly inhibit Src, such as by binding to a peptide binding site (as opposed to binding at an allosteric site). possible.
Molecular model design experiments were performed to show that the compounds of the invention fit within the model Src substrate site (see, eg, US Pat. Nos. 7,005,445 and 7,070,936). Also, to target other kinases, the Src kinase inhibitor backbone using model design by simply using different sets of side chains present on the molecule and / or modifying the backbone itself. Has been renewed.
Although we do not want to be bound by theory, in cells many kinases are embedded in a multiprotein signaling complex, so that certain kinases (eg, in intracellular conformation) are compared. , Src) extracellular conformation is considered to be significantly different. Therefore, the peptide substrate binding site is not well formed in the isolated kinase (as shown by the X-ray structure of Src), so that the activity of the peptide substrate binding inhibitor on the isolated kinase is weak. Conceivable. Binding to this site in the assay of isolated kinases involves a very low proportion of total protein in the assay of the isolated enzyme in which the inhibitor is in the same conformation as the conformation present inside the cell. It is necessary to capture. Therefore, it is necessary to have a large excess of inhibitor excrete a large amount of enzyme from the catalytic cycle in the assay to make it detectable.
However, for cell line assays, a large excess of inhibitor is not needed as peptide binding sites are expected to form. In the cell-based Src assay, SH2 and SH3 domain-binding proteins have already transitioned to the Src conformation so that the peptide substrate binding site is fully formed. Therefore, since all of the enzymes are in a tightly bound conformation, even low concentrations of inhibitors can remove the enzymes from the catalytic cycle.
The overwhelming majority of known kinase inhibitors are ATP-competitive and show low selectivity in the assay panel of isolated kinases. However, many of the compounds of the present invention are considered to be peptide substrate binding inhibitors. Therefore, conventional high-performance screening of compounds against isolated enzymes such as Src cannot find the compounds of the invention.

In another embodiment, the compound does not inhibit the binding of ATP to protein kinases. In one embodiment, the compound inhibits the Src family protein kinase.

cancer Recent literature to consider as a widely useful approach to the treatment of cancer without causing significant toxicity supports the targeting of pp60c-src (Src). For example, tumors that exhibit enhanced EGF receptor-type PTK signaling or overexpress associated Her-2 / neu receptors constitutively activate Src and enhance tumor invasiveness. Inhibition of Src in these cells causes growth arrest, induces apoptosis, and reverses the transformed phenotype (Karni et al. (1999) Oncogene). 18 (33): 4654-4662). It is known that transformed cells grow in a scaffold-independent form due to abnormally high Src activity. This was apparently that extracellular matrix signaling increased Src activity in the FAK / Src pathway, which is a coordinated form with cell division signaling, thereby activating it normally. It is caused by the fact that it blocks the fistula apoptosis mechanism. As a result, FAK / Src inhibition in tumor cells can trigger apoptosis, as it would trigger an apoptotic mechanism that would normally have begun to activate upon disruption in the absence of extracellular matrix (Hisano et al., et al. Proc.Annu.Meet.Am.Assoc.Cancer Res.38: A1925 (1997)). In addition, decreased VEGF mRNA expression was observed during Src inhibition, and tumors derived from these Src-inhibiting cell lines showed decreased angioplasty expression. (Ellis et al., Journal of Biological Chemistry 273 (2): 1052-1057 (1998)).
Src has been proposed to be a "universal" target for cancer treatment as it has been found to be overactivated in growing human tumors (Levitzki, Current Opinion in Cell Biology,). 8, 239-244 (1996); Levitzki, Anti-Cancer Drug Design, 11, 175-182 (1996)). The potential benefits of Src inhibition for cancer treatment are four-fold inhibition of uncontrolled cell proliferation caused by autocrine growth factor loop effects, inhibition of apoptosis-induced metastasis during extracellular matrix-absent disruption, VEGF. Inhibition of tumor neovascularization due to reduced levels and seems to be hypotoxic.
Prostate cancer cells have been reported to overexpress both paxillin and pl30cas and are overphosphate esterified (Tremblay et al., Int.J.Cancer, 68, 164-171, 1996). , Can be the primary target for Src inhibitors.
The present invention comprises a pharmaceutical composition comprising substantially pure KX2-391 or a salt, solvate, hydrate or prodrug thereof and at least one pharmaceutically acceptable excipient. Includes methods of preventing or treating cell proliferation disorders by administering to a subject in need of it. The present invention comprises substantially pure KX2-391 bis-HCl. The present invention comprises substantially pure KX2-391 mesylate.
For example, cell proliferation disorders are precancerous or cancerous.

The cell proliferation disorder treated or prevented by the compounds of the present invention may be an hyperproliferative disorder. The cell proliferation disorder treated or prevented by the compounds of the invention may be psoriasis.
Treatment or prevention of proliferative disorders may be by inhibition of tyrosine kinases. For example, the tyrosine kinase may be Src kinase or focal adhesion kinase (FAK).
The present invention is also a method of treating or preventing cancer or growth disorders in a subject, wherein an effective amount of substantially pure KX2-391, or a salt, solvate, hydrate or prodrug thereof. , For example, relating to a method comprising administering a composition comprising substantially pure KX2-391, KX2-391 · 2HCl or KX2-391 · MSA.
Hearing impairment As described herein, the compounds of the invention may be used to protect a subject from deafness or to prevent hearing loss in a subject. The compound may be administered to protect against deafness, before exposure to noise, or before administration of a drug that induces deafness to prevent or reduce the level of deafness. .. Drugs that induce deafness include chemotherapeutic agents (eg, platinum-based agents that target hair cells) and aminoglycoside-based antibacterial agents. The compounds of the present invention may exert a synergistic effect with a specific anticancer agent. For example, the expected inhibitors can be screened in a primary human tumor tissue assay, in particular, to find synergistic effects with other known anti-cancer agents. In addition, protein kinase inhibitors can reduce the toxicity of certain anticancer agents (eg, platinum-based agents that are toxic to the cochlea and kidneys), thereby increasing the dose.
Alternatively, the compounds of the present invention may be used to treat deafness in a subject. In this embodiment, the compound is administered to a subject after the onset of deafness to reduce the level of deafness. The compounds of the invention are involved in the regulation of the kinase cascade and are, for example, kinase inhibitors, non-ATP competitive inhibitors, tyrosine kinase inhibitors, Src inhibitors or focal adhesion kinase (FAK) modulators. Without wishing to be bound by theory, it is believed that administration of kinase inhibitors prevents apoptosis of cochlear hair cells, which prevents deafness. In one embodiment, the compounds of the invention are administered to a subject suffering from deafness to prevent further deafness. In another embodiment, the compounds of the invention are administered to a subject suffering from hearing loss in order to restore lost hearing. In particular, after exposure to noise, the close cell junctions between cochlear hair cells and the interaction of cells with the extracellular matrix are dividing and under pressure. By applying pressure to these close cell junctions, tyrosine kinases act as molecular switches, interact with focal adhesion kinases, and undergo intracellular apoptosis by a complex signaling pathway that transmits the signal of cell-matrix division to the nucleus. Start. Administration of a kinase inhibitor is thought to prevent the initiation of apoptosis in this cascade.
Confirmation of apoptosis in noise-exposed cochlear ducts has created several new possibilities for preventing noise-induced hearing loss (NIHL) (Hu et al .; 2000, Acta. Otolaryngol., 120, 19). -twenty four). For example, by administering antioxidants to the round window of the ear, the ear can be protected from NIHL (Hight et al.; 2003, Hear.Res., 179, 21-32; Hu et al.; Hear.Res.113, 198-206). Specifically, in chinchillas, NIHL was alleviated by administration of FDA-approved antioxidant compounds (NL-acetylcysteine (L-NAC) and salicylate) (Kopke et al .; 2000, Hear). .Res., 149, 138-146). In addition, Harris et al. Recently described the prevention of NIHL with Src-PTK inhibitors (Harris et al.; 2005, Hear.Res., 208, 14-25). Therefore, administration of the compounds of the invention that regulate the activity of kinases is hypothesized to be useful in treating deafness.
Changes in cell adhesion or cell stress can activate a variety of signals by integrin activation and phosphorylation of PTKs, including the Src family of tyrosine kinases. Src interactions have been linked to signaling pathways that modify the cytoskeleton and activate various protein kinase cascades that regulate cell survival and gene transcription (Giancotti and Ruoslahti; 1999, Science, 285, 1028-1032). Considered in). In fact, recent results indicate that cell-based detached outer hair cells (OHCs) underwent apoptotic cell death after exposure to intense noise. Specifically, Src The PTK signaling cascade may be involved in both metabolic and mechanically induced inhibition of apoptosis in the sensory cells of the cochlear duct. In a recent study, the Src inhibitor provided protection from noise in the 4 kHz octave band for 4 hours at 106 dB, which activates Src-PTK in outer hair cells after exposure to noise. It shows that there is a possibility (Harris et al., 2005, Hear.Res., 208, 14-25). Therefore, the compounds of the present invention that regulate the activity of Src are useful in the treatment of deafness.
Another aspect of the invention is a method of protecting a subject from deafness or treating the subject's deafness in an effective amount of substantially pure KX2-391, or a salt, solvate, water thereof. Includes methods comprising administering a solvate or prodrug, eg, a composition comprising substantially pure KX2-391, KX2-391 / 2HCl or KX2-391 / MSA.
In one embodiment, the compound is administered before the onset of deafness. In another embodiment, the compound is administered after the onset of deafness.
In one embodiment, the compound is administered in combination with a deafness-causing agent, such as a cis platinum or aminoglycoside antibacterial agent. In another embodiment, the compound is administered in combination with a drug that targets hair cells.
osteoporosis The present invention relates to a method of protecting a subject from osteoporosis or treating a subject's osteoporosis. The method comprises administering to a subject an effective amount of a compound of the invention to protect or treat osteoporosis. To protect against osteoporosis, the compound may be administered before the onset of osteoporosis. Alternatively, compounds may be used to treat osteoporosis in the subject. In one embodiment, the compound is administered to the subject after the occurrence of osteoporosis in order to reduce the level of osteoporosis.
The compounds of the invention can be, for example, non-ATP competitive inhibitors. The compounds of the present invention can regulate the kinase signaling cascade depending on the particular side chain and backbone modification selected. The compounds of the present invention can be kinase inhibitors. For example, the compound can be a protein tyrosine kinase (PTK) inhibitor. High proline tyrosine kinases (PYK2; also known as cell adhesion kinase β, related adhesion-focused tyrosine kinases, or calcium-dependent tyrosine kinases), and adhesion spot kinases (FAKs) are non-receptive regulated by a variety of extracellular stimuli. Members of a different family of body protein tyrosine kinases (Avraham et al., 2000, Cell Signal, 12, 123-133; Schlaepfer et al., 1999, Prog.Biophys.Mol.Biol., 71, 435-478). The compounds of the invention can be Src inhibitors. Src deficiency has been shown to be associated with osteoporosis in mice due to loss of osteoclast function (Soriano et al., 1991, Cell, 64, 693-702). Alternatively, the compounds of the invention can regulate the expression of interleukin-1 receptor-related kinase M (IRAK-M). Mice without IRAK-M develop severe osteoporosis, which is associated with accelerated osteoclast differentiation, increased osteoclast half-life, and their activation (Hongmei et al.; 2005, J.Exp.Med., 201, 1169-1177).
Multinucleated osteoclasts arise from the fusion of mononuclear phagocytes and play a major role in bone growth and remodeling by bone reabsorption. Osteoclasts are multinucleated, terminally differentiated cells that degrade the mineralization matrix. In normal bone tissue, there is a balance between osteoblast-induced bone formation and osteoclast-induced bone reabsorption. When this dynamic and well-controlled process is out of balance, bone reabsorption can outweigh bone formation, resulting in bone loss. Osteoclasts are essential for bone development and remodeling, so increased numbers and / or activity of them can lead to diseases associated with systemic bone loss (eg, osteoporosis) and local bone loss. Other related diseases (eg, rheumatoid arthritis, periodontal disease) occur.
Both osteoclasts and osteoblasts control a number of cellular signaling pathways involved in protein kinases. Activation of osteoclasts is initiated by adhesion to bone, cytoskeletal rearrangement, formation of sealed zones, and formation of polarized wavy membranes. Protein tyrosine kinase 2 (PYK2) is thought to be involved in signal transduction from the cell surface to the cytoskeleton because it is tyrosine phosphorylated and activated by adhesion initiation signaling in osteoclasts (Duong et al., 1998, J.Clin.Invest., 102, 881-892). Recent evidence has pointed out that reduced PYK2 protein levels result in inhibition of osteoclast formation and bone reabsorption in vitro (Duong et al., 2001, J.Bio.Chem., 276, 7484-7492). Therefore, inhibition of PYK2 or other protein tyrosine kinases can reduce the level of osteoporosis by reducing osteoclast formation and bone reabsorption. Therefore, without being bound by theory, administration of the compounds of the invention regulates kinase (eg, PTK) activity and thus inhibits osteoclast formation and / or bone reabsorption, which leads to osteoporosis. Is assumed to be treated.
As confirmed in studies of Src-deficient mice and in vitro cell experiments, Src tyrosine kinases stand out as promising therapeutic targets for bone disease, with osteoclasts (positive) and osteoblasts (negative). It suggests a regulatory role for Src in both. In osteoclasts, Src plays an important role in motility, polarity, survival, activation (wavy edge formation) and adhesion, especially by mediating various signaling pathways in cytokines and integrin signaling. (Parang and Sun; 2005, Expert Opin.Ther.Patents, 15, 1183-1207). In addition, targeted disruption of the src gene in mice induces ossification, a disorder characterized by reduced bone reabsorption, without showing any overt morphological or functional abnormalities in other tissues or cells. (Soriano et al.; 1991, Cell, 64, 693-702). src<sup>-/-</sup>The osteopetrosis phenotype of mice is cell self-sustaining and is usually due to a deficiency of mature osteoclasts expressing high levels of Src protein. (Horne et al.; 1991, Cell, 119, 1003-1013). Src inhibitors are thought to reduce fractures and promote bone formation by limiting the effectiveness of Src tyrosine kinases, which induce osteoclast activity and inhibit osteoblasts. Inhibition of Src kinase activity may be useful in the treatment of osteoporosis, as osteoclasts normally express high levels of Src (Missbach et al.; 1999, Bone, 24, 437-449). Therefore, the PTK inhibitors of the present invention that regulate the activity of Src are useful in the treatment of osteoporosis.
For example, a defect in the Src gene in mice results in only one drawback: the inability to form wavy edges, resulting in osteoclasts that do not reabsorb bone. However, the bone reabsorption function of osteoclasts was rescued in these mice by inserting the kinase-deficient Src gene (Schwartzberg et al. (1997) Genes & Development 11: 2835-2844). This is clearly sufficient for the presence of the Src protein to supplement and activate other PTKs (essential for maintaining osteoclast function) in osteoclasts essential for signaling complexes. This suggests that Src kinase activity can be inhibited in vivo without inducing only known toxicity.
Another aspect of the invention is a method of protecting a subject from osteoporosis or treating a subject's osteoporosis in an effective amount of substantially pure KX2-391, or a salt, solvate, water thereof. Includes methods comprising administering a solvate or prodrug, eg, a composition comprising substantially pure KX2-391, KX2-391 / 2HCl or KX2-391 / MSA.
In one embodiment, the compound is administered prior to the onset of osteoporosis. In another embodiment, the compound is administered after the onset of osteoporosis.
obesity As described herein, the compounds of the invention may be used to protect a subject from obesity or to prevent subject obesity. To protect against obesity, the compound may be administered prior to the onset of obesity in the subject. For example, the compound may be administered to prevent or reduce weight gain. Alternatively, the compound may be used to treat obesity in a subject. The compounds of the invention are involved in the modulation of the kinase signaling cascade and are, for example, kinase inhibitors, non-ATP competitive inhibitors, tyrosine kinase inhibitors, protein tyrosine phosphatase inhibitors, or protein-tyrosine phosphatase 1B inhibitors.
Obesity is often associated with diabetes and increased insulin resistance in insulin-responsive tissues such as skeletal muscle, liver and white adipose tissue (Klaman et al .; 2000, Mol.Cell.Biol, 20, 5479-5489). Insulin plays an important role in the regulation of glucose homeostasis, lipid metabolism and energy balance. Insulin signaling is initiated by the binding of insulin to the insulin receptor (IR), the receptor tyrosine kinase. Insulin binding begins with autophosphorylation of IR on multiple tyrosine residues and induces a cascade of phosphorylation events. Autophosphorylation enhances IR kinase activity and induces downstream signaling events. Most of the action of insulin is defined by the promoting action of protein tyrosine kinase and the inhibitory action of protein tyrosine phosphatase. Proper insulin signaling minimizes large fluctuations in blood glucose levels and ensures adequate delivery of glucose to cells. Since insulin stimulation causes multiple tyrosyl phosphorylation events, enhanced activity of one or more protein-tyrosine phosphatases (PTPs) can result in insulin resistance that can lead to obesity. In fact, increased PTP activity has been reported in several insulin-resistant states, including obesity (Ahmad et al .; 1997, Metabolism, 46, 1140-1145). Therefore, without wishing to be bound by theory, administration of the compounds of the invention regulates kinase (eg, PTP) activity, thereby treating obesity in a subject.
Insulin signaling begins with the activation of IR by tyrosine phosphorylation and ends with the uptake of glucose into cells by the glucose transporter GLUT4 (Saltiel and Kahn; 2001, Nature, 414, 799-806). Activated IR should then be deactivated and return to its basal state (a process in which protein-tyrosine phosphatase-1B (PTP-1B) is thought to be involved) (Ahmad et al.; 1997, J. Biol. Chem). ., 270, 20503-20508). Disruption of the gene encoding PTP-1B in mice makes them sensitive to insulin and increases resistance to dietary obesity (Elchebly et al.; 1999, Science, 283, 1544-1548; Klaman et al.; 2000, Mol. Cell.Biol, 20, 5479-5489). The decrease in fat accumulation in PTP-1B-deficient mice was due to a significant decrease in adipocyte mass without reducing adipocyte count (Klaman et al., 2000, Mol.Cell.Biol, 20, 5479-5489). ). In addition, leanness in PTP-1B-deficient mice was accompanied by an increase in basal metabolic rate and total energy expenditure without significant changes in mRNA expression of uncoupled proteins. Disruption of the PTP-1B gene has been shown to be able to regulate insulin signaling and dietary obesity in vivo by altering the activity of PTP-1B. Therefore, although not bound by theory, administration of compounds of the invention that regulate insulin signaling (eg, PTP-1B activity) is useful in the treatment of subject obesity.
Another aspect of the invention is a method of protecting a subject from obesity or treating obesity, wherein an effective amount of substantially pure KX2-391, or a salt, solvate, hydrate or hydrate thereof. Includes methods comprising administering a prodrug, eg, a composition comprising substantially pure KX2-391, KX2-391 / 2HCl or KX2-391 / MSA.
In one embodiment, the compound is administered before the subject becomes obese. In another embodiment, the compound is administered after the subject becomes obese.
Diabetes As described herein, the compounds of the invention may be used to protect a subject from diabetes or to prevent diabetes. To protect against diabetes, the compound may be administered before the onset of diabetes in the subject. Alternatively, the compound may be used to treat diabetes in a subject. The compounds of the invention may be involved in the modulation of the kinase signaling cascade, eg, kinase inhibitors, non-ATP competitive inhibitors, tyrosine kinase inhibitors, phosphatase tensin homolog (PTEN) inhibitors on chromosome 10, or sequence homology. 2-Containing inositol 5'-phosphatase 2 (SHIP2) inhibitor.
Type II diabetes (T2DM) is a disorder of dysregulated energy metabolism. Energy metabolism is primarily regulated by the hormone insulin, a potent anabolic drug that promotes the synthesis and storage of proteins, carbohydrates and lipids, inhibits their breakdown and restores the circulatory system. The action of insulin is initiated by its binding to the tyrosine kinase receptor, causing autophosphorylation and increased catalytic activity of the kinase (Patti et al., 1998, J. Basic Clin. Physiol. Pharmacol. 9, 89-109). .. By tyrosine phosphorylation, the insulin receptor substrate (IRS) protein interacts with the p85 regulatory subunit of phosphatidylinositol 3-kinase (PI3K) to activate the enzyme and move to a specific intracellular position depending on the cell type. Will result in labeling. The enzyme is a lipid product, phosphatidylinositol-3,4,5-triphosphate (PtdIns (3,4,5) P.<sub>3</sub>), Which regulates the localization and activity of numerous proteins (Kido et al.; 2001, J. Clin. Endocrinol. Metab., 86, 972-979). PI3K has important roles in insulin-stimulated glucose uptake and storage, inhibition of lipolysis, and regulation of liver gene expression (Saltiel et al.; 2001, Nature, 414, 799-806). Overexpression of the dominant interfering form of PI3K may block glucose uptake and translocation of glutamate transporter 4, GLUT4 to the cell membrane (Quon et al.; 1995, Mol.Cell.Biol, 15, 5403-5411). Therefore, administration of compounds of the invention that regulate kinase (eg, PI3K) activity and thus increase glucose uptake is useful in the treatment of diabetes.
PTEN is a major regulator of PI3K signaling in many cell types and functions as a tumor suppressor by antagonizing the anti-apoptotic, proliferative and hypertrophic activities of the PI3K pathway (Goberdhan et al.; 2003, Hum. Mol. Genet., 12, R239-R248; Leslie et al .; 2004, J. Biochem., 382, 1-11). I don't want to be bound by theory, but PTEN is PtdIns (3,4,5) P.<sub>3</sub>Dephosphorylation of the molecule attenuates the PI3K pathway, making this important lipid second messenger PtdIns (4,5) P.<sub>2</sub>It is thought that it will deteriorate. Recent studies have shown that PtdIns (3,4,5) P is due to a 50% reduction in endogenous PTEN protein using short interfering RNA (siRNA).<sub>3</sub>Increased insulin dependence and glucose uptake at levels were enhanced (Tang et al.; 2005, J. Biol. Chem., 280, 22523-22529). Therefore, although not bound by theory, administration of the compounds of the invention that regulate PTEN activity and thus result in increased glucose uptake is hypothesized to be useful in the treatment of diabetes.
Also, PtdIns (3,4,5) P<sub>3</sub>Levels are also regulated by a family of SRC homology 2 (SH2) -containing inositol 5'-phosphatase (SHIP) proteins, namely SHIP1 and SHIP2 (Lazar and Saltiel; 2006, Nature Reviews, 5, 333-342). Among other insulin-sensitive tissues, SHIP2 expressed in skeletal muscle is PtdIns (3,4,5) P.<sub>3</sub>PtdIns (3,4) P<sub>2</sub>Catalyzing the conversion to (Pesesse et al.; 1997; Biochem Biophys.Res.Commun., 239, 697-700; Backers et al.; 2003, Adv. Enzyme Regul., 43, 15-28; Chi et al.; 2004, J. et al. Biol Chem., 279, 44987-44995; Sleeman et al.; 2005, Nature Med., 11, 199-205). Insulin-stimulated PtdIns (3,4,5) P due to overexpression of SHIP2<sub>3</sub>Levels are significantly reduced in harmony with the proposed volume of SHIP2, and activation of PI3K downstream effectors is diminished (Ishihara et al.; 1999, Biochem.Biophys.Res.Commun., 260, 265-272). .. Therefore, although not bound by theory, administration of the compounds of the invention that regulate SHIP2 activity and thus result in increased glucose uptake is hypothesized to be useful in the treatment of diabetes.
Another aspect of the invention is a method of protecting a subject from diabetes or treating diabetes in an effective amount of substantially pure KX2-391, or a salt, solvate, hydrate or hydrate thereof. Includes methods comprising administering a prodrug, eg, a composition comprising substantially pure KX2-391, KX2-391 / 2HCl or KX2-391 / MSA.
In one embodiment, the compound is administered before the onset of diabetes. In another embodiment, the compound is administered after the disease has developed.
Eye disease As described herein, the compounds of the invention may be used to protect a subject from eye (eye) disease or to prevent eye disease. To protect against eye disease, the compound may be administered prior to the onset of eye disease in the subject. Alternatively, the compounds may be used to treat subject eye disorders such as macular degeneration, retinopathy and macular edema. The compounds of the invention are involved in the regulation of the kinase cascade, such as kinase inhibitors, non-ATP competitive inhibitors, tyrosine kinase inhibitors, such as vascular endothelial growth factor (VEGF) receptor tyrosine kinase inhibitors.
New angioplasty of the physiologically avascular cornea can occur that threatens vision. Proliferative retinopathy, predominantly diabetic retinopathy and age-related macular degeneration, is characterized by increased vascular permeability, resulting in retinal edema and subretinal fluid accumulation, as well as the proliferation of new blood vessels that are prone to bleeding. Angioplasty, the formation of new blood vessels from existing capillaries, is an integral part of normal development and numerous pathological processes. VEGF, a central mediator of the complex cascade of neovascularization and an important permeability factor, is an attractive target for new therapeutic agents. VEG is a ligand for two membrane-bound tyrosine kinase receptors, VEGFR-1 and VEGFR-2. Ligand binding causes VEGFR dimerization and transphosphorylation, followed by activation of the intercellular tyrosine kinase domain. Subsequent intracellular signaling axis) causes cell proliferation, migration and survival of the vascular endothelium. Therefore, without wishing to be bound by theory, administration of compounds of the invention that regulate kinase activity, such as tyrosine kinase activity, resulting in inhibition of neovascularization and / or neovascularization. It is assumed to be useful in the treatment of eye diseases such as macular degeneration, retinopathy and / or macular edema.
Macular degeneration is characterized by VEGF-mediated retinal leakage (increased vascular permeability) and abnormal growth of small blood vessels behind the eye (new angiogenesis). VEGF has been identified in the neovascular membrane of both diabetic retinopathy and age-related macular degeneration, and the intraocular level of this factor correlates with the severity of neovascularization in diabetic retinopathy (Kvanta et al; 1996). , Invest.Ophthal.Vis.Sci, 37, 1929-1934 .; Aiello et al., 1994, N.Engl.J.Med., 331, 1480-1487). In these models, the therapeutic antagonism of VEGF results in a significant inhibition of new angioplasty in both the retina and choroid, as well as reduced vascular permeability (Aiello et al.; 1995, Proc. Natl. Acad. Sci.USA., 92, 10457-10461; Krzystolik et al.; 2002, Arch.Ophthal., 120, 338-346; Qaum et al.; 2001, Invest.Ophthal.Vis.Sci., 42, 2408-2413). Therefore, although not bound by theory, administration of the compounds of the invention that regulate VEGF activity and result in inhibition of neovascularization and / or neovascularization is associated with eye diseases such as macular edema. It is assumed to be useful in the treatment of degeneration, retinopathy and / or macular edema.
Another aspect of the invention is a method of protecting or treating a subject from eye diseases such as macular degeneration, retinopathy, macular edema, etc., in an effective amount of substantially pure KX2-391. , Or a composition comprising a salt, solvate, hydrate or prodrug thereof, eg, substantially pure KX2-391, KX2-391 / 2HC1 or KX2-391 / MSA. including.
In one embodiment, the compound is administered prior to the onset of eye disease. In another embodiment, the compound is administered after the onset of eye disease.
stroke The compounds of the present invention are used in methods of treating, preventing, or alleviating a stroke in a subject at risk of suffering a stroke, suffering a stroke, or having suffered a stroke. The compounds of the present invention are useful in methods of treating patients undergoing post-stroke rehabilitation.
Stroke, also known as a cerebrovascular attack (CVA), is an acute neurological injury that impedes the blood supply to parts of the brain by blocking arteries or rupturing blood vessels. The part of the brain where the blood supply is disrupted can no longer receive the oxygen and / or nutrients carried by the blood. Brain cells are impaired or necrotic, which impairs the function of that part of the brain or from that part. Oxygen deficiency for more than 60-90 seconds causes the brain tissue to cease functioning and, after a few minutes, suffer irreparable damage that can cause death, or infarction, of the tissue.
Stroke is classified into two main types: ischemic stroke, that is, blockade of blood vessels that supply the brain, and hemorrhagic stroke, that is, hemorrhage in or around the brain. The majority of all strokes are ischemic strokes. Ischemic stroke is generally divided into thrombotic stroke, embolic stroke, systemic hypoperfusion (diversion stroke), or venous thrombosis. In thrombotic stroke, the thrombus-forming process occurs in the affected artery, and a thrombus, or blood clot, gradually narrows the lumen of the artery, thereby blocking blood flow to the distal tissue. Such blood clots usually form around arteriosclerotic plaques. There are two types of thrombotic stroke, which are classified based on the type of blood vessel in which the thrombus is formed. Macrovascular thrombotic stroke involves the common and internal carotid arteries, the spine, and the Circle of Willis. Small vascular thrombotic stroke involves the intracerebral arteries, the branches of the Willis artery ring, the base of the middle cerebral artery, and the arteries starting from the distal vertebral and basilar arteries.
Thrombi can cause embolic stroke, which, if not occluded, becomes a thrombus at that point if the thrombus ruptures. A thrombus is a particle or fragment that travels elsewhere in the arterial bloodstream. Embolic stroke refers to the blockade of an arterial access to a part of the brain by a thrombus. Thrombi are often blood clots, but can also be plaques away from atherosclerotic blood vessels, or many other substances that can be fat, air, or cancerous cells. Since thrombosis occurs elsewhere, topical treatment only temporarily resolves the problem. Therefore, the cause of thrombus must be confirmed. There are four types of embolic stroke: known cardiac causes, potential cardiac or aortic causes (from transthoracic or transesophageal echo); arterial causes. Things; and some of unknown causes.
Systemic hypoperfusion is a decrease in blood flow to all parts of the body. This is most commonly caused by cardiac arrest or cardiac arrhythmia, or impaired cardiac output due to decreased blood excretion as a result of myocardial infarction, pulmonary embolism, pericardial effusion, or bleeding. Hypoxemia (ie, low blood oxygen content) can lead to rapid hypoperfusion. Since the decrease in blood flow is general, all parts of the brain, especially the "watershed" range, which is the border area supplied by the main cerebral arteries, are affected. Blood flow to these areas does not necessarily stop, and blood flow to the point of brain injury can be reduced.
Veins in the brain function to flush blood back to the body. When a vein is occluded due to thrombosis, blood flow is blocked, blood flows back, and cerebral edema occurs. This cerebral edema can cause ischemic and hemorrhagic strokes. This generally occurs in the bizarre disease venous sinus thrombosis.
Stroke is one or more of the various techniques known in the art, such as neurological tests, blood tests, CT scans (without contrast enhancement), MRI scans, Doppler ultrasonography and arterography (ie, no radiation). Diagnosis is made in a subject or patient using an arterial radiography) after injecting a permeable substance into the bloodstream. If the stroke is confirmed by contrast, various other tests are done to determine if there is a cause around the obstruction. Such tests include, for example, carotid artery ultrasound / Doppler tests (to detect carotid artery stenosis); electrocardiogram (ECG) and echocardiography (an arrhythmia in the heart that can spread to the cerebrovascular by blood flow and as a result). To confirm blood clots); Holter monitor examinations to confirm intermittent arrhythmia and cerebrovascular angiography (if bleeding is thought to be due to an aneurysm or arteriovenous malformation).
Compounds useful in these methods of treating, preventing or alleviating stroke or the symptoms associated with stroke are compounds that regulate the progression of the kinase signaling cascade during or after stroke. In some embodiments, the compound is a kinase inhibitor. For example, the compound is a tyrosine kinase inhibitor. In one embodiment, the tyrosine kinase inhibitor is an Src inhibitor. For example, the compounds used in the methods described herein for treating, preventing or alleviating stroke or the symptoms associated with stroke are allosteric inhibitors of the progression of the kinase signaling cascade during or after stroke.

Inhibition of Src activity has been shown to protect the brain during stroke (see Paul et al., Nature Medicine, vol. 7 (2): 222-227 (2001), which is cited by reference. The whole is incorporated herein). Vascular Endothelial Growth Factor (VEGF) produced in response to ischemic injury has been shown to promote vascular permeability. Src kinase regulates VEGF-mediated VP in the brain, then stroke, and administration of Src inhibitors before and after stroke reduces edema, improves cerebral perfusion, and volume of infarct after injury. Studies have shown that is reduced (Paul et al., 2001). Therefore, Src inhibition may be useful in the treatment, treatment and alleviation of secondary injury after stroke.

Symptoms of stroke include sudden numbness or weakness, especially on one side of the body; sudden confusion, difficulty speaking, difficulty understanding conversation; sudden visual difficulty in one or both eyes; sudden difficulty walking, dizziness, or Loss of balance or coordination; or sudden, severe headache of unknown cause.
In general, stroke has three stages of treatment: prevention, immediate stroke treatment, and post-stroke rehabilitation. Treatments to prevent initial or recurrent strokes are based on treatment of the risk factors underlying the stroke, such as hypertension, high cholesterol, atrial fibrillation and diabetes. In acute stroke treatment, an attempt is made to stop the stroke by quickly dissolving the clot that causes the ischemic stroke or by stopping the bleeding of the hemorrhagic stroke. Post-stroke rehabilitation helps individuals overcome the disability caused by stroke damage. Pharmacotherapy and medication are the most common treatments for stroke. The most common types of drugs used to prevent or treat stroke are antithrombotic agents (eg, antiplatelet agents and anticoagulants) and thrombolytic agents. The compound is administered to a subject at risk of suffering a stroke, suffering a stroke, or having suffered a stroke before, during, or after a stroke, or in any combination thereof.

In one embodiment, the compound is administered before a stroke occurs. In another embodiment, the compound is administered after a stroke has occurred.
Atherosclerosis The compounds of the present invention are used in methods of treating, preventing or alleviating atherosclerosis or its symptoms in subjects at risk of or suffering from atherosclerosis.
Atherosclerosis is a disease that affects the blood vessels of an artery and is commonly referred to as "hardening" of the artery. Atherosclerosis results from the formation of multiple plaques in the arteries. Atherosclerotic plaques are counteracted by arterial dilation, which ultimately causes plaque rupture or narrowing of the arteries (ie, narrowing), which in turn causes the blood supply to the organs to which the blood vessels provide blood. There will be a shortage. Alternatively, excessive arterial dilation processes that are counteracted eventually result in an aneurysm. These complications are chronic, slowly progressing, and cumulative. Most commonly, soft plaques suddenly rupture, forming blood clots (ie, blood clots) that rapidly slow or stop blood flow, thereby receiving blood from the arteries. To death. This catastrophic event is called an infarction. For example, coronary thrombosis of the coronary arteries causes a myocardial infarction commonly known as a heart attack. Myocardial infarction occurs when atherosclerotic plaques slowly build up inside the coronary arteries and then suddenly rupture, blocking the entire artery and blocking downstream blood flow.
Atherosclerosis and acute myocardial infarction are diagnosed in patients using a variety of clinical and / or laboratory tests, such as physical examination, radiation or ultrasonography, and blood analysis. For example, a doctor or clinician may hear a subject's arterial sound to detect an abnormal humming sound called a brui. Bruy can be heard by placing a stethoscope over the affected artery. Alternatively or additionally, the clinician or physician can examine the pulse, for example, in the legs or feet, to find abnormalities such as weakness or lack. A physician or clinician may perform a blood test to test cholesterol levels or to test heart enzyme levels such as creatine kinase, troponin and lactate dehydrogenase to detect abnormalities. For example, the troponin subunit I or T, which is very specific for the myocardium, rises before permanent damage occurs. Positive troponin in chest pain can accurately predict that myocardial infarction is likely to occur in the near future. Other tests for diagnosing atherosclerosis and / or myocardial infarction include, for example, EKG (ECG), which measures the rate and regularity of a subject's heartbeat; a test that compares blood pressure in the ankle to blood pressure in the upper arm. Chest X-ray to measure ankle / upper arm blood pressure index; Ultrasonic analysis of arteries; CT scan of the area of interest; Angiography; Exercise stress test, nuclear heart scanning; and nuclear magnetism of the heart Resonance imaging (MRI) and positron radial tomography (PET) scans are included.
Compounds useful in these methods of treating, preventing or alleviating atherosclerosis or its symptoms are compounds that regulate the kinase signaling cascade in patients at risk or suffering from atherosclerosis. is there.

The compounds used in the methods of treating, preventing or alleviating atherosclerosis or associated symptoms described herein are non-ATP competitive inhibitors of the kinase signaling cascade involved in atherosclerosis. Is preferable.
Intracellular signaling by Src appears to play an important role in increasing vascular permeability, known as vascular permeability (VP). For example, vascular endothelial growth factor (VEGF) produced in response to ischemic injury, including myocardial infarction, has been shown to promote vascular permeability. Studies have shown that inhibition of Src kinase reduces VEGF-mediated VP (Parang and Sun, Expert) See Opin.Ther.Patents, vol.15 (9): 1183-1206 (2005), which is incorporated herein by reference in its entirety). It has been demonstrated that mice treated with Src inhibitors have reduced tissue damage associated with trauma or damage to blood vessels after myocardial infarction (eg, US Patent Publication No. Cheresh et al.). See 20040214836 and 200303130209, these publications are incorporated herein by reference in their entirety). Therefore, inhibition of Src may be useful in the prevention, treatment or alleviation of secondary injury after injury due to atherosclerosis, such as myocardial infarction.
Atherosclerosis is generally asymptomatic until the arteries are significantly narrowed to restrict blood flow or cause a sudden occlusion. Symptoms depend on the site of plaque or stenosis, such as the heart, brain, other biological organs and legs, or any part of the body. Early symptoms of atherosclerosis are when the body needs more oxygen, for example during exercise, when a person feels chest pain due to a lack of oxygen in the heart (angina), or to the legs. It can be pain or spasm when feeling leg cramps due to lack of oxygen. Narrowing of the arteries that supply blood to the brain can cause dizziness or transient ischemic attack (TIA), in which case the symptoms or signs of stroke last for less than 24 hours. Typically, these symptoms progress gradually.
Symptoms of myocardial infarction are characterized by varying degrees of chest pain, discomfort, sweating, weakness, chills, vomiting, and arrhythmias, and can also cause loss of consciousness. Chest pain is the most common symptom of acute myocardial infarction and is often described as tension, tightness, and squeezing. Pain may spread to the chin, neck, arms, back and epigastrium, most often to the left arm or neck. Chest pain is more likely to occur if myocardial infarction lasts longer than 30 minutes. Patients with myocardial infarction may exhibit shortness of breath (dyspnea), especially if the decrease in myocardial contractility due to the infarction is sufficient to cause left ventricular insufficiency with embryonic congestion or even embryonic edema.

In one embodiment, the compound is administered before the onset of symptoms of atherosclerosis. In another embodiment, the compound is administered after the onset of symptoms of atherosclerosis.
Neuropathic pain The compounds of the present invention treat neuropathic pain, such as chronic neuropathic pain, or its symptoms in subjects at risk of, suffering from, or have suffering from neuropathic pain. Used in preventative or mitigating methods.
Neuropathic pain, also known as neuralgia, is qualitatively different from normal nociceptive pain. Neuropathic pain is usually present as a constant burning and / or "tingling" and / or "electric shock" -like sensation. The difference between nociceptive pain and neuropathic pain, for the "normal" nociceptive pain is to stimulate only the pain nerve, neuropathic pain, Shiba Shiba, pain sensations in the same range Due to the fact that it stimulates both nerves and non-painful sensory nerves (eg, nerves that respond to tactile, warm, and cold sensations), resulting in the generation of signals that the spinal cord and brain would not normally receive. ..
Neuropathic pain is usually a complex chronic pain condition with tissue damage. For neuropathic pain, the nerve fibers themselves can be damaged, dysfunctional, or injured. These damaged nerve fibers send false signals to other pain centers. The effects of nerve fiber injury include changes in nerve function both at the site of injury and in the area surrounding the injury.
Neuropathic pain is diagnosed in a subject or patient using one or more different laboratory and / or clinical techniques known in the art, such as a medical examination.
Compounds useful in treating, preventing or alleviating neuropathic pain, such as chronic neuropathic pain, or the symptoms associated with neuropathic pain, are compounds that regulate the kinase signaling cascade involved in neuropathic pain. Is.
c-Src has been shown to regulate the activity of the N-methyl-D-aspartate (NMDA) receptor (Yu et al., Proc.Natl.Acad.Sci.USA, vol.96: 7697- See 7704 (1999), which is incorporated herein by reference in its entirety). Studies have shown that PP2, a low molecular weight Src kinase inhibitor, reduces phosphorylation of the NMDA receptor NM2 subunit (Guo et al., J. Neuro., Vol. 22: 6208-6217 (2002). ) Reference, the document is incorporated herein by reference in its entirety).

Hepatitis B The compounds of the present invention are used in methods of treating, preventing or alleviating hepatitis B or its symptoms in subjects at risk or suffering from hepatitis B.
Hepatitis B virus, a member of the hepadnavirus family, has a protein core particle containing a viral genome in the form of double-stranded DNA with a single-stranded region and an outer lipid-based envelope with an embedded protein. It is composed of. Encapsular proteins are involved in viral binding and release into susceptible cells. The internal capsid rearranges the DNA genome into the nucleus of the cell, where the viral mRNA is transcribed. Along with the transcript encoding the X protein, three subgenome transcripts encoding the envelope protein are created. A fourth pregenomic RNA is transcribed, which is transported to the cytosol to translate viral polymerases and core proteins. Polymerase and pregenomic RNA are capsidated in the aggregation of core particles, where reverse transcription of the pregenomic RNA into genomic DNA occurs by the polymerase protein. Mature core particles then exit the cell through the normal secretory pathway, but acquire the envelope along the way.
Hepatitis B is one of several known nonretroviral viruses that employ reverse transcription as part of the replication process. Other viruses that use reverse transcription include, for example, HTLV or HIV.
During HBV infection, the host's immune response causes both hepatocyte damage and viral clearance. Congenital immune responses do not play an important role in these processes, but adaptive immune responses, especially virus-specific cytotoxic T lymphocytes (CTLs), are responsible for almost all causes of liver damage associated with HBV infection. Become. CTL also eliminates the virus by producing antiviral cytokines that can kill infected cells and expel HBV from living hepatocytes. Liver damage is initiated and mediated by CTL, but non-antigen-specific inflammatory cells can exacerbate CTL-induced immunopathology, and platelets can promote the accumulation of CTL in the liver.
Hepatitis B is diagnosed in patients using any variety of clinical and / or laboratory tests, such as health examinations, and blood or serum analysis. For example, blood or serum is tested for the presence of viral antigens and / or antibodies produced by the host. In general hepatitis B trials, detection of hepatitis B surface antigens (HBsAg) is used to screen for the presence of infection. This is the first detectable viral antigen that appears during this viral infection, but because this antigen is cleared by the host, it may not be present in the early stages of infection and is undetectable in the later stages of infection. It may be possible. During this "window" where the host remains infected but is successfully eliminating the virus, IgM antibodies (anti-HBc IGM) against hepatitis B core antigens may be the only serological evidence of the disease.
Immediately after the appearance of HBsAg, another antigen named hepatitis B e-antigen (HBeAg) appears. Traditionally, the presence of HBeAg in host serum has been implicated in a very high rate of virus replication, but some hepatitis B virus variants do not produce any "e" antigens. There are also things. During the natural course of infection, HBeAg is eliminated and antibodies against the "e" antigen (anti-HBe) are produced shortly thereafter. This conversion is usually associated with a dramatic reduction in virus replication. If the host can eliminate the infection, then HBsAg will eventually become undetectable, followed by antibodies to the hepatitis B surface antigen (anti-HB). Those who are negative for HBsAg but positive for anti-HB are those who have ruled out the infection or have been previously vaccinated. Many people who are positive for HBsAg have little viral growth and may therefore have little risk of long-term complications or infection of others.
Compounds useful in these methods of treating, preventing, or alleviating hepatitis B or its symptoms are compounds that regulate the kinase signaling cascade in patients at risk or suffering from hepatitis B. In some embodiments, the compound is a kinase inhibitor. For example, the compound is a tyrosine kinase inhibitor. In one embodiment, the tyrosine kinase inhibitor is an Src inhibitor. The compounds used in the methods described herein for treating, preventing or alleviating hepatitis B or its symptoms are preferably allosteric inhibitors of the kinase signaling cascade involved in hepatitis B. The compounds used in the methods described herein for treating, preventing, or alleviating hepatitis B or the symptoms associated with hepatitis B are non-ATP competitive inhibitors of the kinase signaling cascade involved in hepatitis B. It is preferable to have.
Src plays a role in the replication of hepatitis B virus. The virus-encoded transcription factor HBx activates Src in the steps required by the transmission of the HBV virus (eg, Klein et al., EMBO J., vol. 18: 5019-5027 (1999); Klein et al. , Mol.Cell.Biol., Vol.17: 6427-6436 (1997), each of which is incorporated herein by reference in its entirety). Therefore, Src inhibition, which in turn inhibits Src-mediated transmission of the HBV virus, may be useful in the treatment, treatment or alleviation of hepatitis B or its symptoms.
The compounds of the present invention prevent hepatitis B or symptoms associated with hepatitis B. Treat or alleviate. Symptoms of hepatitis B typically develop within 30-180 days after exposure to the virus. However, up to half of all people infected with the hepatitis B virus are asymptomatic. Symptoms of hepatitis B are often compared to influenza, such as loss of appetite; fatigue; nausea and vomiting, generalized itching; liver pain (eg, right side of the abdomen, under the lower thorax), jaundice, And changes in excretory function.
The compounds of the invention are administered alone as pharmaceutical compositions or in combination with any of a variety of known hepatitis B treatments such as interferon α, lamivudine (Epivir-HBV) and Baraclude (entecavir).
Another aspect of the invention is a method of protecting a subject from hepatitis B or treating hepatitis B in an effective amount of substantially pure KX2-391, or a salt, solvate thereof. Includes methods comprising administering a hydrate or prodrug, eg, a composition comprising substantially pure KX2-391, KX2-391 / 2HCl or KX2-391 / MSA.

Control of immune system activity As described herein, the compounds of the invention control the activity of the subject's immune system, thereby controlling autoimmune diseases such as rheumatoid arthritis, multiple sclerosis, sepsis and lupus, and implants. It may be used to protect against rejection and allergic diseases, or to prevent them. Alternatively, the compound may be used to treat an autoimmune disease of the subject. For example, the compound results in a reduction in the severity of symptoms or an imminent cessation of progression of the subject's autoimmune disease. The compounds of the invention are involved in the modulation of the kinase signaling cascade and are, for example, kinase inhibitors, non-ATP competitive inhibitors, tyrosine kinase inhibitors, such as Src inhibitors, p59fyn (Fyn) inhibitors or p561ck (Lck) inhibitors.
Autoimmune diseases are diseases caused by disruption of self-tolerance, such as the adaptive immune system responding to self-antigens and mediating cell and tissue damage. Autoimmune diseases can be organ-specific (eg, thyroiditis or diabetes) or systemic (eg, systemic lupus erythematosus). T cells regulate the cell-mediated immune response in the adaptive immune system. Under normal conditions, T cells express antigen receptors (T cell receptors) that recognize peptide fragments of heterologous proteins bound to automajor histocompatibility complex molecules. The earliest perceived events after stimulation with the T cell receptor (TCR) include activation of Lck and Fyn, which are TCR residues on tyrosine residues within the immunoreceptor tyrosine system activation motif. (Zamoyska et al., 2003, Immunol. Rev., 191, 107-118). Tyrosine kinases such as Lck (a member of the Src family of protein tyrosine kinases) play an important role in cell signaling and modulation of cell proliferation by phosphorylating peptide and protein tyrosine residues (Levitzki; 2001). , Top.Curr.Chem., 211, 1-15; Longati et al .; 2001, Curr.Drug Targets, 2, 41-55; Qian and Weiss; 1997, Curr.Opin.Cell Biol, 9, 205-211). Therefore, although not bound by theory, administration of compounds of the invention that regulate tyrosine kinase (eg, Src) activity is hypothesized to be useful in the treatment of autoimmune diseases.
Both tyrosine kinases lck and fyn are activated in the TCR pathway, so inhibitors of lck and / or fyn have potential utility as autoimmune agents (Palacios and Weiss; 2004, Oncogene, 23, 7990). -8000). Lck and Fyn are predominantly expressed by T cells throughout their lifetime. The role of Lck and Fyn in T cell development, homeostasis and activation has been demonstrated by animal and cell line studies (Parang and Sun; 2005, Expert). Opin.The.Patents, 15, 1183-1207). Lck activation is involved in autoimmune disease and graft rejection (Kamens et al .; 2001, Curr. Opin. Investig. Drugs, 2, 1213-1219). The result is that the lck (-) jarcat cell line proliferates, produces cytokines, and increases intracellular calcium, inositol phosphate, and tyrosine phosphorylation in response to stimulation of T cell receptors. Indicates that it cannot be done (Straus and Weiss; 1992, Cell., 70, 585-593; Yamasaki et al.; 1996, Mol. Cell.Biol, 16, 7151-7160). Therefore, drugs that inhibit lck effectively block T cell function, act as immunosuppressants, autoimmune diseases such as rheumatoid arthritis, multiple sclerosis and lupus, and graft rejection and allergies. It has potential utility in the area of sexual disorders (Hanke and Pollok; 1995, Inflammation Res., 44, 357-371). Therefore, without being bound by theory, administration of compounds of the invention that regulate one or more members of the Src family of protein tyrosine kinases (eg, lck and / or fyn) is a treatment for autoimmune diseases. It is assumed to be useful in.
Another aspect of the invention is a method of controlling the activity of the immune system of a subject, wherein an effective amount of substantially pure KX2-391, or a salt, solvate, hydrate or prodrug thereof. For example, a method comprising administering a composition comprising substantially pure KX2-391, KX2-391 · 2HCl or KX2-391 · MSA.

Protein kinases catalyze the transfer of γ-phosphate from ATP to the hydroxyl groups on the side chains of Ser / Thr or Tyr in proteins and peptides, and various important cellular functions (probably the most notable signal). It is a large type of enzyme that is closely involved in the regulation of transmission, differentiation and proliferation. There are about 2,000 different protein kinases in the human body, each phosphorylating a particular protein / peptide substrate, all of which bind to the same secondary substrate ATP in a highly conserved pocket. It is estimated that. About 50% of the known proto-oncogene products are protein tyrosine kinases (PTKs), and their kinase activity has been shown to result in cellular transformation.
PTK can be divided into two categories: membrane receptor PTK (eg, growth factor receptor PTK) and non-receptor PTK (eg, Src family of proto-oncogene products and focal adhesion kinase (FAK)).

In addition, the structures and other compounds discussed herein include all of their atropisomers. An "atropisomer" is a type of steric isomer in which two isomer atoms are arranged spatially differently. Atropisomers are present by the restricted rotation caused by the binding rotation of large groups around the central bond. Such atropisomers usually exist as mixtures, but as a result of recent advances in chromatographic techniques, it is possible to separate mixtures of two atropisomers when selected.
The term "crystal polymorph" or "polymorph" or "crystal morphology" means a crystal structure in which a compound (or a salt or solvate thereof) can all crystallize in different crystal packed arrangements with the same elemental composition. .. Different crystal forms usually have different X-ray diffraction patterns, infrared spectra, melting points, densities, hardness, crystal forms, optical and electrical properties, stability and solubility. Depending on the recrystallization solvent, crystallization rate, storage temperature and other factors, one type of crystal morphology may predominate. Crystal polymorphs of compounds can be produced by crystallization under different conditions.
Furthermore, the compounds of the invention, such as salts of the compounds, can also exist in hydrated or non-hydrated (anhydride) forms or as solvates with other solvent molecules. Non-limiting examples of hydrates include monohydrates, dihydrates and the like. Non-limiting examples of solvates include ethanol solvates, acetone solvates and the like.
"Solvate" means a solvent addition form comprising a stoichiometric or non-stoichiometric amount of solvent. Some compounds have a tendency to confine solvent molecules of constant molar ratio in the crystalline solid state, thereby forming a solvate. If the solvent is water, the solvate formed is a hydrate, and if the solvent is an alcohol, the solvate formed is alcoholate. A hydrate is formed by combining one or more water molecules and one substance, and in the hydrate, water has a molecular state of H.<sub>2</sub>Keeping as O, such a combination can form one or more hydrates.
"Tautomer" refers to a compound that exists in a simple and quick equilibrium state, although its structure differs significantly in the arrangement of atoms. It should be understood that the compounds of the invention can be presented as different tautomers.

Should be done.
Some compounds of the invention may exist in tautomeric form. Tautomers are also intended to be included within the scope of the present invention.
The compounds, salts and prodrugs of the invention can be present in several tautomeric forms, including enol and imine forms, keto and enamine forms, and geometric isomers and mixtures thereof. All such tautomeric morphologies are within the scope of the present invention. The tautomer is present in solution as a mixture of a set of tautomers. In the solid form, one tautomer is usually predominant. The present invention includes all tautomers of the compound, even if only one tautomer is described.
A tautomer is one of two or more structural isomers that exist in equilibrium and are easily converted from one isomer form to another. This reaction causes the formal transfer of hydrogen atoms at the same time as the switching of adjacent conjugated double bonds. In a solution capable of tautomerization, a chemical equilibrium of the tautomer is achieved. The exact ratio of tautomers depends on several factors, including temperature, solvent and pH. The concept of tautomers that can be converted to each other by tautomerization is called tautomerism.
Of the various types of tautomerization possible, two are commonly observed. In keto-enol tangle, electrons and hydrogen atoms migrate at the same time. Ring-chain tautomerism is indicated by glucose. Ring-chain tautomerization occurs as a result of reacting an aldehyde group (-CHO) in a sugar chain molecule with a hydroxy group (-OH) in the same molecule, resulting in a ring (cyclic) form.
Tautomerization is base: 1. deprotonation; 2. formation of delocalized anions (eg, enolate); 3. protonation at different positions of anions; acid: 1. protonation; 2. non-protonation. Formation of localized cations; 3. Catalyzed by deprotonation at different positions adjacent to the cations.
Common tautomer pairs are ketone-enol, amide-nitrile, lactam-lactim, amide-imidic acid tautomers in heterocycles (eg, in the nucleic acid bases guanidine, timine and cytosine), amines. -Enamine and Enamine-Enamine.
Therefore, unless otherwise suggested, isomers resulting from asymmetric carbon atoms (eg, all enantiomers and diastereomers) should be understood to be within the scope of the present invention. Such isomers can be obtained in substantially pure form by classical separation techniques and by stereochemically controlled synthesis. In addition, the structures, other compounds and moieties discussed herein also include all of their tautomers. Alkenes may include either E or Z geometry, where appropriate. The compounds of the present invention may exist in the form of stereoisomers and can therefore be prepared as individual stereoisomers or mixtures.
