FIELD
[0002] The present disclosure relates generally to inhibitors of kinase, therapeutic methods of use, and manufacture thereof.
BACKGROUND
[0003] Although inflammation can be a protective mechanism in response to harmful stimuli such as invasion of pathogens and tissue damages, chronic inflammation is an important underlying factor in many human diseases such as neurodegeneration, rheumatoid arthritis, autoimmune and inflammatory diseases, and cancer. Similarly, the activation of cell death pathways, such as necrosis and apoptosis which are useful in eliminating infected or damaged cells, is also an important underlying mechanism for human diseases, including acute and chronic neurodegenerative diseases.
[0004] Receptor-interacting protein kinase 1 is a key regulator of inflammation, apoptosis and necroptosis. Receptor-interacting protein kinase 1 has an important role in modulating inflammatory responses mediated by nuclear-factor kappa-light chain enhancer of activated B cells (NF-κΒ). More recent research has shown that its kinase activity controls necroptosis, a form of necrotic cell death, which was traditionally thought to be passive and unregulated, and is characterized by a unique morphology. Further, receptor-interacting protein kinase 1 is part of a pro-apoptotic complex indicating its activity in regulating apoptosis.
[0005] The receptor-interacting protein kinase 1 is subject to complex and intricate regulatory mechanisms, including ubiquitylation, deubiquitylation and phosphorylation. These regulatory events collectively determine whether a cell will survive and activate an inflammatory response or die through apoptosis or necroptosis. Dysregulation of receptor-interacting protein kinase 1 signaling can lead to excessive inflammation or cell death, and conversely, research has shown that inhibition of receptorinteracting protein kinase 1 can be effective therapies for diseases involving inflammation or cell death.

[0047] “Heterocyclyl” refers to a saturated or unsaturated cyclic alkyl group, with one or more ring heteroatoms independently selected from nitrogen, oxygen and sulfur. The term “heterocyclyl” includes heterocycloalkenyl groups (i.e. the heterocyclyl group having at least one double bond), bridgedheterocyclyl groups, fused-heterocyclyl groups, and spiro-heterocyclyl groups. A heterocyclyl may be a single ring or multiple rings wherein the multiple rings may be fused, bridged, or spiro. In certain embodiments, heterocyclyl may comprise one or more oxo (C=O) or N-oxide (N-O-) moieties. Any nonaromatic ring containing at least one heteroatom is considered a heterocyclyl, regardless of the attachment (i.e., can be bound through a carbon atom or a heteroatom). Further, the term heterocyclyl is intended to encompass any non-aromatic ring containing at least one heteroatom, which ring may be fused to an aryl or heteroaryl ring, regardless of the attachment to the remainder of the molecule. As used herein, heterocyclyl has 2 to 20 ring carbon atoms (i.e., C2-20 heterocyclyl), 2 to 12 ring carbon atoms (i.e., C2-12 heterocyclyl), 2 to 10 ring carbon atoms (i.e., C2-10 heterocyclyl), 2 to 8 ring carbon atoms (i.e., C2-8 heterocyclyl), 3 to 12 ring carbon atoms (i.e., C3-12 heterocyclyl), 3 to 8 ring carbon atoms (i.e., C3-8 heterocyclyl), or 3 to 6 ring carbon atoms (i.e., C3-6 heterocyclyl); having 1 to 5 ring heteroatoms, 1 to 4 ring heteroatoms, 1 to 3 ring heteroatoms, 1 to 2 ring heteroatoms, or 1 ring heteroatom independently selected from nitrogen, sulfur or oxygen.

Also used herein, the term “spiro-heterocyclyl” refers to a ring system in which a three- to ten-membered heterocyclyl has one or more additional ring, wherein the one or more additional ring is three- to ten-membered cycloalkyl or three- to ten-membered heterocyclyl, where a single atom of the one or more additional ring is also an atom of the three- to tenmembered heterocyclyl. Examples of the spiro-heterocyclyl rings include bicyclic and tricyclic ring systems, such as 2-oxa-7-azaspiro[3.5]nonanyl, 2-oxa-6-azaspiro[3.4]octanyl, and 6-oxa-lazaspiro[3.3]heptanyl. Examples of the fosed-heterocyclyl rings include, but are not limited to, 1,2,3,4tetrahydroisoquinolinyl, 4,5,6,7-tetrahydrothieno[2,3-c]pyridinyl, indolinyl, and isoindolinyl, where the heterocyclyl can be bound via either ring of the fused system.

Also, unless indicated explicitly otherwise, where combinations of groups are referred to herein as one moiety, e.g. arylalkyl, the last mentioned group contains the atom by which the moiety is attached to the rest of the molecule.
[0063] The terms “optional” or “optionally” means that the subsequently described event or circumstance may or may not occur, and that the description includes instances where said event or circumstance occurs and instances in which it does not. Also, the term “optionally substituted” refers to any one or more hydrogen atoms on the designated atom or group may or may not be replaced by a moiety other than hydrogen.

In an embodiment, each of said alkyl, alkenyl, alkynyl, alkoxy, thioalkyl, aryl, aralkyl, cycloalkyl, cycloalkylalkyl, haloalkyl, heterocyclyl, heterocyclylalkyl, heteroaryl, and/or heteroarylalkyl are independently optionally substituted with one or more oxo, alkyl, halo, amino, hydroxy or alkoxy. In addition, each of the foregoing substituents may also be optionally substituted with one or more of the above substituents.
[0068] Polymers or similar indefinite structures arrived at by defining substituents with further substituents appended ad infinitum (e.g., a substituted aryl having a substituted alkyl which is itself substituted with a substituted aryl group, which is further substituted by a substituted heteroalkyl group, etc.) are not intended for inclusion herein. Unless otherwise noted, the maximum number of serial substitutions in compounds described herein is three. For example, serial substitutions of substituted aryl groups with two other substituted aryl groups are limited to ((substituted aryl)substituted aryl) substituted aryl. Similarly, the above definitions are not intended to include impermissible substitution patterns (e.g., methyl substituted with 5 fluorines or heteroaryl groups having two adjacent oxygen ring atoms). Such impermissible substitution patterns are well known to the skilled artisan. When used to modify a chemical group, the term “substituted” may describe other chemical groups defined herein. Unless specified otherwise, where a group is described as optionally substituted, any substituents of the group are themselves unsubstituted. For example, in certain embodiments, the term “substituted alkyl” refers to an alkyl group having one or more substituents including hydroxy, halo, alkoxy, acyl, oxo, amino, cycloalkyl, heterocyclyl, aryl, and heteroaryl. In other embodiments, the one or more substituents may be further substituted with halo, alkyl, haloalkyl, hydroxy, alkoxy, cycloalkyl, heterocyclyl, aryl, or heteroaryl, each of which is substituted. In other embodiments, the substituents may be further
260674/2 substituted with halo, alkyl, haloalkyl, alkoxy, hydroxy, cycloalkyl, heterocyclyl, aryl, or heteroaryl, each of which is unsubstituted.
[0069] Any compound or formula given herein, is also intended to represent unlabeled forms as well as isotopically labeled forms of the compounds. Isotopically labeled compounds have structures depicted by the formulas given herein except that one or more atoms are replaced by an atom having a selected atomic mass or mass number. Examples of isotopes that can be incorporated into compounds of the disclosure include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorous, fluorine and chlorine, such as, but not limited to <sup>2</sup>H (deuterium, D), <sup>3</sup>H (tritium), <sup>11</sup>C, <sup>13</sup>C, <sup>14</sup>C, <sup>15</sup>N, <sup>18</sup>F, <sup>31</sup>P, <sup>32</sup>P, <sup>35</sup>S, <sup>36</sup>Cl and <sup>125</sup>I. Various isotopically labeled compounds of the present disclosure, for example those into which radioactive isotopes such as <sup>3</sup>H, <sup>13</sup>C and <sup>14</sup>C are incorporated. Such isotopically labelled compounds may be useful in metabolic studies, reaction kinetic studies, detection or imaging techniques, such as positron emission tomography (PET) or single-photon emission computed tomography (SPECT) including drug or substrate tissue distribution assays or in radioactive treatment of patients.
[0070] The disclosure also includes “deuterated analogs” of compounds of Formula I in which from 1 to n hydrogens attached to a carbon atom is/are replaced by deuterium, in which n is the number of hydrogens in the molecule. Such compounds exhibit increased resistance to metabolism and are thus useful for increasing the half-life of any compound of Formula I when administered to a mammal, particularly a human. See, for example, Foster, “Deuterium Isotope Effects in Studies of Drug Metabolism,” Trends Pharmacol. Sci. 5(12):524-527 (1984). Such compounds are synthesized by means well known in the art, for example by employing starting materials in which one or more hydrogens have been replaced by deuterium.
[0071] Deuterium labelled or substituted therapeutic compounds of the disclosure may have improved DMPK (drug metabolism and pharmacokinetics) properties, relating to distribution, metabolism and excretion (ADME). Substitution with heavier isotopes such as deuterium may afford certain therapeutic advantages resulting from greater metabolic stability, for example increased in vivo half-life, reduced dosage requirements and/or an improvement in therapeutic index. An <sup>18</sup>F, <sup>3</sup>H, <sup>11</sup>C labeled compound may be useful for PET or SPECT or other imaging studies. Isotopically labeled compounds of this disclosure and prodrugs thereof can generally be prepared by carrying out the procedures disclosed in the schemes or in the examples and preparations described below by substituting a readily available isotopically labeled reagent for a non-isotopically labeled reagent. It is understood that deuterium in this context is regarded as a substituent in the compound of Formula I.
[0072] The concentration of such a heavier isotope, specifically deuterium, may be defined by an isotopic enrichment factor. In the compounds of this disclosure any atom not specifically designated as a particular isotope is meant to represent any stable isotope of that atom. Unless otherwise stated, when a position is designated specifically as “H” or “hydrogen”, the position is understood to have hydrogen at
260674/2 its natural abundance isotopic composition. Accordingly, in the compounds of this disclosure any atom specifically designated as a deuterium (D) is meant to represent deuterium.
[0073] In many cases, the compounds of this disclosure are capable of forming acid and/or base salts by virtue of the presence of amino and/or carboxyl groups or groups similar thereto.
[0074] Provided are also pharmaceutically acceptable salts, hydrates, solvates, tautomeric forms, stereoisomers, and prodrugs of the compounds described herein. “Pharmaceutically acceptable” or “physiologically acceptable” refer to compounds, salts, compositions, dosage forms and other materials which are useful in preparing a pharmaceutical composition that is suitable for veterinary or human pharmaceutical use.
[0075] The term “pharmaceutically acceptable salt” of a given compound refers to salts that retain the biological effectiveness and properties of the given compound, and which are not biologically or otherwise undesirable. “Pharmaceutically acceptable salts” or “physiologically acceptable salts” include, for example, salts with inorganic acids and salts with an organic acid. In addition, if the compounds described herein are obtained as an acid addition salt, the free base can be obtained by basifying a solution of the acid salt. Conversely, if the product is a free base, an addition salt, particularly a pharmaceutically acceptable addition salt, may be produced by dissolving the free base in a suitable organic solvent and treating the solution with an acid, in accordance with conventional procedures for preparing acid addition salts from base compounds. Those skilled in the art will recognize various synthetic methodologies that may be used to prepare nontoxic pharmaceutically acceptable addition salts. Pharmaceutically acceptable acid addition salts may be prepared from inorganic and organic acids. Salts derived from inorganic acids include hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, phosphoric acid, and the like. Salts derived from organic acids include acetic acid, propionic acid, glycolic acid, pyruvic acid, oxalic acid, malic acid, malonic acid, succinic acid, maleic acid, fumaric acid, tartaric acid, citric acid, benzoic acid, cinnamic acid, mandelic acid, methanesulfonic acid, ethanesulfonic acid, p-toluene-sulfonic acid, salicylic acid, and the like. Likewise, pharmaceutically acceptable base addition salts can be prepared from inorganic and organic bases. Salts derived from inorganic bases include, by way of example only, sodium, potassium, lithium, ammonium, calcium and magnesium salts. Salts derived from organic bases include, but are not limited to, salts of primary, secondary and tertiary amines, such as alkyl amines (i.e., NH2(alkyl)), dialkyl amines (i.e., HN(alkyl)2), trialkyl amines (i.e., N(alkyl)3), substituted alkyl amines (i.e., NH2(substituted alkyl)), di(substituted alkyl) amines (i.e., HN(substituted alkyl)2), tri(substituted alkyl) amines (i.e., N(substituted alkyl)3), alkenyl amines (i.e., NH2(alkenyl)), dialkenyl amines (i.e., HN(alkenyl)2), trialkenyl amines (i.e., N(alkenyl)3), substituted alkenyl amines (i.e., NH2(substituted alkenyl)), di(substituted alkenyl) amines (i.e., HN(substituted alkenyl)2), tri(substituted alkenyl) amines (i.e., N(substituted alkenyl)3, mono-, di- or tri- cycloalkyl amines (i.e., NH2(cycloalkyl), HN(cycloalkyl)2, N(cycloalkyl)3), mono-, di- or tri- arylamines (i.e., NH2(aryl), HN(aryl)2, N(aryl)3), or mixed amines, etc. Specific examples of suitable amines include, by
260674/2 way of example only, isopropylamine, trimethyl amine, diethyl amine, tri(iso-propyl) amine, tri(n-propyl) amine, ethanolamine, 2-dimethylaminoethanol, piperazine, piperidine, morpholine, N-ethylpiperidine, and the like.
[0076] The term “hydrate” refers to the complex formed by the combining of a compound of Formula I and water.
[0077] A “solvate” refers to an association or complex of one or more solvent molecules and a compound of the invention. Examples of solvents that form solvates include, but are not limited to, water, isopropanol, ethanol, methanol, dimethylsulfoxide, ethylacetate, acetic acid, and ethanolamine.
[0078] Some of the compounds exist as tautomers. Tautomers are in equilibrium with one another. For example, amide containing compounds may exist in equilibrium with imidic acid tautomers.
Regardless of which tautomer is shown, and regardless of the nature of the equilibrium among tautomers, the compounds are understood by one of ordinary skill in the art to comprise both amide and imidic acid tautomers. <sup>,</sup>Thus, the amide containing compounds are understood to include their imidic acid tautomers. Likewise, the imidic acid containing compounds are understood to include their amide tautomers.
[0079] <sup>,</sup>The compounds disclosed herein, or their pharmaceutically acceptable salts include an asymmetric center and may thus give rise to enantiomers, diastereomers, and other stereoisomeric forms that may be defined, in terms of absolute stereochemistry, as (R)- or (5)- or, as (D)- or (L)- for amino acids. <sup>,</sup>The disclosure is meant to include all such possible isomers, as well as their racemic and optically pure forms. Optically active (+) and (-), (R)- and (5)-, or (D)- and (L)- isomers may be prepared using chiral synthons or chiral reagents, or resolved using conventional techniques, for example, chromatography and fractional crystallization. Conventional techniques for the preparation/isolation of individual enantiomers include chiral synthesis from a suitable optically pure precursor or resolution of the racemate (or the racemate of a salt or derivative) using, for example, chiral high pressure liquid chromatography (HPLC). When the compounds described herein contain olefinic double bonds or other centres of geometric asymmetry, and unless specified otherwise, it is intended that the compounds include both E and Z geometric isomers. Likewise, all tautomeric forms are also intended to be included.
[0080] ‘‘Stereoisomers are isomers that differ only in the way the atoms are arranged in space and include enantiomers and diastereomers. In certain embodiments, a “stereoisomer” refers to a compound made up of the same atoms bonded by the same bonds but having different three-dimensional structures, which are not interchangeable. <sup>,</sup>The present disclosure contemplates various stereoisomers and mixtures thereof and includes “enantiomers,” which refers to two stereoisomers whose molecules are nonsuperimposeable mirror images of one another.
[0081] ‘‘Enantiomers” are a pair of stereoisomers that are non-superimposable mirror images of each other. A 1:1 mixture of a pair of enantiomers is a racemic mixture.
260674/2
[0082] ‘‘Diastereoisomers” are stereoisomers that have at least two asymmetric atoms, but which are not mirror-images of each other.
[0083] The absolute stereochemistry is specified according to the Cahn Ingold Prelog R S system. When the compound is a pure enantiomer the stereochemistry at each chiral carbon may be specified by either R or S. Resolved compounds whose absolute configuration is unknown are designated (+) or (-) depending on the direction (dextro- or laevorotary) that they rotate the plane of polarized light at the wavelength of the sodium D line.
[0084] “Prodrugs” means any compound which releases an active parent drug according to Formula I or any other formula described herein in vivo when such prodrug is administered to a mammalian subject. Prodrugs of a compound of Formula I or any other formula described herein are prepared by modifying functional groups present in the compound of Formula I or any other formula described herein in such a way that the modifications may be cleaved in vivo to release the parent compound. Prodrugs may be prepared by modifying functional groups present in the compounds in such a way that the modifications are cleaved, either in routine manipulation or in vivo, to the parent compounds. Prodrugs include compounds of Formula I or any other formula described herein wherein a hydroxy, amino, carboxyl or sulfhydryl group in a compound of Formula I or any other formula described herein is bonded to any group that may be cleaved in vivo to regenerate the free hydroxy, amino, or sulfhydryl group, respectively. Examples of prodrugs include, but are not limited to esters (e.g., acetate, formate and benzoate derivatives), amides, guanidines, carbamates (e.g., Ν,Ν-dimethylaminocarbonyl) of hydroxy functional groups in compounds of Formula I or any other formula described herein and the like. Preparation, selection and use of prodrugs is discussed in T. Higuchi and V. Stella, Pro-drugs as Novel Delivery Systems, Vol. 14 of the A.C.S. Symposium Series; Design of Prodrugs, ed. H. Bundgaard, Elsevier, 1985; and in Bioreversible Carriers in Drug Design, ed. Edward B. Roche, American Pharmaceutical Association and Pergamon Press, 1987.
[0085] As used herein, “pharmaceutically acceptable carrier” or “pharmaceutically acceptable excipient” or “excipient” includes any and all solvents, dispersion media, coatings, antibacterial and antifungal agents, isotonic and absorption delaying agents and the like. The use of such media and agents for pharmaceutically active substances is well known in the art. Except insofar as any conventional media or agent is incompatible with the active ingredient, its use in the therapeutic compositions is contemplated. Supplementary active ingredients can also be incorporated into the compositions.

Compound preparation
[0403] Where the preparation of starting materials is not described, these are commercially available, known in the literature, or readily obtainable by those skilled in the art using standard procedures. Where it is stated that compounds were prepared analogously to earlier examples or intermediates, it will be appreciated by the skilled person that the reaction time, number of equivalents of reagents and temperature can be modified for each specific reaction and that it may be necessary or desirable to employ different work-up or purification techniques. Where reactions are carried out using microwave irradiation, the microwave used is a Biotage Initiator. The actual power supplied varies during the course of the reaction in order to maintain a constant temperature.

Biological Assays
[1102] Compounds were tested for binding and cellular kinase activity according to the following protocols. proGST-hRIPKl (8-327) enzyme was generated by Proteros GmbH by Baculovirus expression system.
[1103] The cellular necroptosis assay (Cell IC50 in Tables 5-7) evaluates the ability of compounds to reverse the necrosis induced by human TNFa. Ten concentrations of the test compounds were assessed in duplicate in two different test occasions. FADD-deficient Jurkat cells were purchased from ATCC (ATCC-CRL-2572) and cultured in suspension in RPMI medium supplemented with 10% heat inactivated of FBS and 1% Pen-Strep. The day of the experiment cells were diluted to a density of
402
260674/2
0.12xl0<sup>5</sup> cells/mL (5,000 cells/well) with culture medium and added (40 pL) into the 384-well plate containing 0.2 pL/well of test compounds and reference compounds (CRCs) (200x). Cell plates were then incubated at 37°C -5% CO2. After 30 min, necroptotic cell death was induced with human TNFa (10 ng/mL) and cell viability was evaluated 48h later by measuring cellular ATP levels using CellTiter-Glo® kit (Promega). Luminescence was read by using Victor V (Perkin Elmer) multilabel plate reader. Data were expressed as % of max viability calculated comparing the values to <sup>,</sup>TNFa untreated control cells which represents 100% of cell viability. CRCs were analysed by Dotmatics and IC50 values were calculated by non-linear regression using 4 parameter-logistic equation.
[1104] Fluorescent Polarization Binding (FP Binding) assay (Berger S.B. et al. (2015) Cell Death Discovery, 1: 15009; Maki J.L. et al. (2012) Anal Biochem., 427(2): 164-174) was performed in polystyrene low volume 384-well black plate, at Room Temperature (RT) in a final volume of 10.1 pl/well using 10 nM of GST-hRIPKl (8-327) enzyme and 5 nM of fluorescent-labeled ligand (14-(2-{[3({2-{[4-(cyanomethyl)phenyl]amino}-6-[(5-cyclopropyl-lH-pyrazol-3-yl)amino]-4-pyrimidinyl}amino) propyl]amino}-2-oxoethyl)-l 6,16,18,18-tetramethyl-6,7,7a,8a,9,10,16,18-octahydrobenzo [2”,3”]indolizino[8”,7”:5',6']pyrano [3',2':3,4]pyrido[l,2-a]indol-5-ium-2-sulfonate.
[1105] Test Compounds were serially diluted in DMSO at 100 fold final concentrations in the assay (1% DMSO final). In each well of a 384-well Plate were dispensed 0.1 pL of compound solution (or DMSO for controls) followed by 5 pL of GST-hRIPKl (8-327) at twice the final concentrations in assay buffer (50 mM HEPES pH 7.5, 10 mM NaCI, 50 mM MgCl<sub>2</sub>, 0.02% CHAPS, 0.5 mM DTT and 0.01% Pluronic F127). For negative control the enzyme addition was replaced by assay buffer only.
[1106] After addition of 5 pL of fluorescent-labeled ligand at twice the final concentrations in assay buffer, the plate was incubated at RT for 30 min. At the end, the binding was measured as FP value with the Envision (PerkinElmer) plate reader using filter for an excitation λ = 531 nm FP and an emission λ = 595 nm FP (S & P-pol).
[1107] GST-hRIPKl (8-327) enzyme was generated by Proteros GmbH by Baculovirus expression system.
[1108] Test compounds were diluted in DMSO and 0.1 pL of solution was dispensed to each well of a 384-well white solid microplate. The assay buffer was 50 mM HEPES pH 7.5, 50 mM NaCI, 30 mM MgC12. The buffer was supplemented with 0.02% CHAPS, 0.01% of Pluronic F127, 0.1 mg/mL BSA and 1 mM DTT. MnC12, 5 mM, was included in the assay buffer on the day of the experiment. The enzymatic reaction comprised 1.5 pg/mL GST-hRIPKl (8-327) and 50 pM ATP for receptor interacting protein kinase 1 and 15 pM ATP. 5 pL of enzyme and 5 pL of ATP were added to the plate at twice the final assay concentration and incubated at room temperature for 3 hours. Following this reaction, 10 pL of ADP-G10 reagent (Promega) was added to each well and incubated for 40 min at room temperature. This stops the kinase reaction and depletes any remaining ATP. 20 pL of ADP-G10
403
260674/2 detection reagent was then added to each well and incubated at room temperature for at least 15 minutes. The detection reagent converts ADP to ATP and introduces luciferase and luciferin to detect ATP. The luminescence is then measured with the Envision (PerkinElmer) plate reader. Test compound inhibition was expressed as percent inhibition of internal assay controls. For concentration response curves, normalized data is fit and IC50 determined using XL-fit (!DBS) for Excel. The IC50 were averaged to determine a mean value, for a minimum of two independent experiments.

[1111] Hie comparative compounds in Table 7 were prepared as described in Examples 12, 146, and 77, respectively, ofWO 2014/125444.
[1112] Hie in vivo efficacy of compounds can be determined in mice using a TNF-driven systemic inflammatory response syndrome model as described by Duprez et. al. (2011, Immunity 35(6), 908-918)
409
260674/2 and Berger et. al. (2015, Cell Death Disc. 1, 15009). In this model system TNF/zVAD (tumor necrosis factor/Z-Val-Ala-DL-Asp-fluoromethylketone, a caspase inhibitor) treatment results in temperature loss and the production of several inflammatory cytokines. The ability of a test compound to inhibit these inflammatory effects can be measured in this model by dosing mice with test compound 15 minutes before administration of TNF/zVAD and measuring the inflammatory response. The dose required to inhibit the inflammatory response is a measure of the compounds efficacy at that dose. Using this model, Compound 42 was orally pre-dosed at 5 mg/kg 15 minutes before intraveneous administration of TNF/zVAD and temperature loss in the mice was measured by an implanted temperature chip. Treatment of mice with 5 mg/kg of Compound 42 resulted in 96% inhibition of temperature loss when compared to TNF/zVAD vehicle treated animals. In comparison, WO 2014/125444 discloses in Table 2 that Example 12, corresponding to Example A of Table 7 above, required a dose of 30 mg/kg to achieve 93% inhibition. The decrease in dosing has a number of important potential advantages, including requiring less frequent administration to a patient, increased patient compliance, and improved safety profile such as lower toxicities while achieving similar efficacy.
[1113] Based on the known crystal structure of comparative Example C and receptor-interacting protein kinase 1 (Harris et al. J. Med. Chern., 2016, 59 (5), pg. 2163-2178), the phenyl carbon atom adjacent to the azepinone moiety (i.e., X<sup>9</sup> of the formulas disclosed herein) interacts with a lipophilic pocket of receptor-interacting protein kinase 1.
[1H4] Certain compounds were found to have significantly improved metabolic stability when X<sup>9</sup> of the formulas disclosed herein is a N atom as compared to a carbon atom. For instance, Compound 42, in comparison to comparative Example A, when tested according to the assay described below, was found to have an average human hepatocyte clearance of 0.8 mL/min/kg versus 6.8 mL/min/kg for comparative Example A. As described in the metabolic stability section below, a CLhep of 6.8 mL/min/kg corresponds to a clearance of approximately 32% of liver blood flow, whereas for Compound 42, a CLhep value of 0.8 mL/min/kg corresponds to a clearance of less than 4% of liver blood flow, demonstrating the significant improvement in stability for compounds when X<sup>9</sup> is a N atom. From the data presented above, it will be apparent to those skilled in the art that compounds with lower human CLhep values should allow for lower human clinical doses, less frequent administration to a patient, increased patient compliance, and improved safety profile such as lower toxicities.
MDCKII-MDR1 Permeability
[1H5] The blood brain barrier (BBB) separates circulating blood from the extracellular fluid of the central nervous system (CNS). The passive membrane permeability (Papp) and the P-gp (P-glycoprotein) substrate efflux potential were determined using the MDCKII-MDR1 cell line as an in vitro model of the effective permeability of a compound through the BBB. A bidirectional assay (Apical to Basolateral (A^B) and Basolateral to Apical (B^A)), in the absence and in the presence of GF120918 (a P-gp
410
260674/2 inhibitor) was conducted using pre-plated MDCKII-MDR1 cells (Coming HTS Transwell-96) obtained from SOLVO Biotechnology. Hie assay was run at 3 μΜ for 90 min (minutes) in triplicate using a HBSS + 12.5 mM HEPES pH 7.4 transport buffer. Following incubation of samples from donor and receiver, wells were removed and measured by LC-MS/MS. Samples were extracted by protein precipitation with acetonitrile containing an appropriate internal standard (IS) having a known mass and molecular weight. Hie precipitate was centrifuged for 10 min at 3000 rpm (revolutions per minute). Hie supernatants were then collected, diluted if necessary, and injected on to the LC-MS/MS system.
Specific parent / daughter ion pairs for the test article and IS were used to selectively measure the test articles. Papp (apparent permeability expressed in nm/sec [nanometer/second]) values were calculated according to the following equation:
ן 0 ן 1/ 00 4 / / ״
Pappynm / sec) = — be — be — (dt ) 00) \A)
[1116] Where dQ/dt is the permeability rate, Co is the initial concentration in the donor solution (expressed as IS ratio), A and B are the surface areas of the filter (the surface area of the cell monolayer).
[1117] Monolayer efflux ratios (ER) were derived using the following equation:
<sub>n</sub> (B - APapp(nml sec) EffluxRatio = -------—------- I
- BPapp(nm / sec))
[1118] Compounds with a MDCKII-MDR1 efflux ratio of less than or equal to 2.5 are likely to demonstrate ability to cross the blood-brain-barrier.
Metabolic Stability (Hepatocytes)
[1119] Hie metabolic stability of compounds was evaluated in human cryopreserved hepatocytes (BioreclamationlVT, NY, USA) in duplicate. Test articles (or controls) were added to a 24-well incubation plate (Becton Dickinson Labware, USA) containing 0.5 xlO<sup>6</sup> hepatocytes/mL in suspension. Hie plate was held at 37 °C and agitated with constant orbital shaking (orbital speed at 350 rpm). At each time point (0, 5, 10, 15, 20, 30, 45, 60, 90, 120, 150 and 180 min) a Tecan Evo robot aspirated 50 pL of the incubation mixture and 100 pL of acetonitrile containing internal standard to quench the reaction. Hie quenched mixtures were dispensed into a 96-well plate along with 120 pL of aqueous solution to equilibrate the solvent content at 37%. Samples were centrifuged (3000 rpm for 10 minutes) and the plate sealed prior to injection onto an LC-MS/MS system.
[1120] Hie appropriate parent / daughter ions were monitored for the test article and IS with the LCMS/MS system. Hie intrinsic clearance (Clint; expressed pL/min/million cells) was determined from the first order elimination constant (k, min<sup>1</sup>־) of test article decay and the volume of the incubation. These values were scaled to intrinsic organ clearance (CL<sub>m</sub>t) using human specific scaling factors (139 X 10<sup>6</sup>
411
260674/2 hepatocytes/g liver and 25.7 g liver/kg body weight). Hie intrinsic organ CL was then converted to the hepatic clearance (CLh<sub>ep</sub>) using the well-stirred model as shown below, where Qh is human hepatic blood flow.
_ Qh *
(״,CL + ״?»־״״׳
[1121] Hepatic clearance is expressed as mL/min/kg. The hepatic clearance relates to the flow of blood through the liver that is completely cleared of the compound. A human CLhep of 20.9 mL/min/kg corresponds to approximately complete compound clearance by the liver or 100% of liver blood flow. Accordingly, a human CLh<sub>ep</sub> of 6 mL/min/kg corresponds to a clearance of approximately 29% of liver blood flow. A human CLh<sub>ep</sub> value of 2 mL/min/kg corresponds to a clearance of approximately 10% of liver blood flow. A human CLh<sub>ep</sub> value of 1 mL/min/kg or less corresponds to a clearance of approximately 5% of liver blood flow or less. A human CLh<sub>ep</sub> value of 0 mL/min/kg corresponds to undetectable compound clearance by the liver.
[1122] In certain embodiments provided are compounds having a CLh<sub>ep</sub> of less than 5, 4, 3, 2, or 1 mL/min/kg when tested according to the above human hepatic stability assay. In certain embodiments such compounds do not readily cross the blood brain barrier. In certain embodiments such compounds have a MDCKII-MDR1 efflux ratio of greater than 2.5.
[1123] In certain embodiments provided are compounds having a CLh<sub>ep</sub> of less than 10, 9, 8, 7, 6, 5, 4, 3, 2, or 1 mL/min/kg when tested according to the above human hepatic stability assay. In certain embodiments such compounds are able to cross the blood brain barrier. In certain embodiments such compounds have a MDCKII-MDR1 efflux ratio of 2.5 or less.
Protein Binding
[1124] Hie protein binding in plasma was determined using a Rapid Equilibrium Dialysis Device (Thermo Scientific RED Device) or 96-well dialyzer apparatus (HTDialysis LLC). Plasma was spiked with test / control compounds to give a final concentration of 0.5 μΜ (plasma). If required, plasma samples were pre-incubated (2 hours at 37 °C) with diisopropyl fluorophosphate (DFP) at the final concentration of 100 μΜ to prevent compound degradation due to amide hydrolysis. Appropriate volumes of spiked samples along with blank phosphate buffer were added to either device and incubated at 37 °C for atotal of 5 hours with agitation at 500 rpm. Following incubation, an equal aliquot of dialysed matrix (plasma or buffer) is added to an equal volume of the opposite blank matrix such that the volume of buffer to plasma are equal. Mixed matrix samples were extracted by protein precipitation using acetonitrile containing the appropriate IS. Samples were then centrifuged for 10 min at 2800 rpm. Supernatants were collected and diluted and then injected on to an HPLC-MS/MS or UPLC-MS/MS system. Samples were analyzed by monitoring the appropriate parent / daughter ion transitions for the test and control compounds. The peak area ratios were used to measure test item concentrations. The
412
260674/2 fraction unbound (Afu) was determined as the ratio of the peak area ratio in buffer divided by the peak area ratio in plasma.
In Vivo Pharmacokinetic (PK) Studies
[1125] The PK properties of test articles were determined in male Sprague-Dawley Crl:CD(SD) rats, male Beagle dogs and male cynomolgus monkeys. Studies were conducted to the highest standards of animal welfare in accordance with national legislation and under approval of the internal animal care and use committees.
[1126] Compounds were administered by IV bolus to animals following an overnight fast. Compounds for IV administration were formulated as solutions using either 1% DMSO (dimethyl sulfoxide):20% PEG400 (polyethylene glycol 400):79% saline, or 5-50% NMP in D5W (5% dextrose in water). Hie formulations were administered at dose volumes ranging from 0.5-2 mL/kg. Hie IV dose ranged from 0.5-1 mg/kg.
[1127] Following dose administration, 8-9 serial blood samples were collected over 24 hours. Samples were mixed with anticoagulant and placed on wet ice prior to processing. Plasma was harvested following centrifugation, extracted using protein precipitation with acetonitrile containing IS. The processed supernatant was analyzed using UPLC or LC-MS/MS using specific parent / daughter ion pairs for the test article and IS. Plasma concentrations were determined using a calibration curve prepared using known concentrations of analyte. Pharmacokinetic parameters utilizing measured concentrations were calculated using Phoenix WinNonlin. The unbound plasma clearance was calculated as the ratio of the total body clearance divided by the fraction unbound in plasma.
