Diphenyl ether compound, process for producing the same, and use

Technical Field

Background Art

Recently in the study of transcription factors associated with marker genes expression induction in adipocytes differentiation, peroxisome proliferator activated receptor (abbreviated as PPAR hereinafter), which is one of intranuclear receptors, has got attention. The cDNAs of PPAR were cloned from various kinds of animals, and plural isoform genes were found, particularly in mammals three types of isoforms (α, δ, γ) are known (see <i>J. Steroid Biochem. Molec. Biol.,</i><u style="single">51,</u> 157 (1994); <i>Gene Expression.,</i><u style="single">4,</u> 281 (1995); <i>Biochem Biophys. Res. Commun.,</i><u style="single">224</u>, 431 (1996); <i>Mol. Endocrinology.,</i> 6, 1634 (1992)). Further, it is known that PPAR γ isoform predominantly expresses in adipose tissues, immune cells, adrenal gland, spleen, small intestine, PPAR α isoform mainly expresses in adipose tissue, liver, retina, and PPAR δ isoform universally expresses without specificity for tissue (see <i>Endocrinology.,</i><u style="single">137</u>, 354 (1996)).

By the way, thiazolidine derivatives such as pioglitazone, ciglitazone, rosiglitazone, troglitazone <i>etc</i>. are known as agents for the treatment of non-insulin dependent diabetes mellitus (NIDDM) and are hypoglycemic agents which are used for the improvement of hyperglycemia in the patients suffering from diabetes. They are also effective for the correction or improvement of hyperinsulinemia, improvement of glucose tolerance and decrease of serum lipid and therefore they are thought to be considerably hopeful as agents for the improvement of insulin resistance.

In addition, one of the intracellular target proteins of these thiazolidine derivatives is exactly PPAR γ and it is resolved that they enhance the transcription activity of PPAR γ (see Endocrinology., <u style="single">137</u>, 4189 (1996); Cell., <u style="single">83</u>, 803 (1995); Cell., <u style="single">83</u>, 813 (1995); J. Biol. Chem., <u style="single">270</u>, 12953 (1995)). Therefore, a PPAR γ activator (agonist) which enhances its transcription activity is thought to be hopeful as a hypoglycemic agent and/or a hypolipidemic agent. Furthermore, since a PPAR γ agonist is known to promote the expression of PPAR γ protein itself (Genes &amp; Development., <u style="single">10</u>, 974 (1996)), an agent which increases the expression of PPAR γ protein itself as well as PPAR γ activating agent is also thought to be clinically useful.

Intracellular receptor, PPAR γ is related to adipocytes differentiation (see J. Biol. Chem., <u style="single">272</u>, 5637 (1997) and Cell., <u style="single">83</u>, 803 (1995)). It is known that thiazolidine derivatives which activate this receptor promote adipocytes differentiation. Recently it was reported that thiazolidine derivatives increase body fat and cause man to gain weight and to become obese (see Lancet., <u style="single">349</u>, 952 (1997)). From these, since PPAR γ activators (agonists) and PPAR γ promotors for its expression that can increase the expression of the protein itself have hypoglycemic effect, hypolipidemic effect, they are expected to be useful as agents for prevention and/or treatment of diseases associated with metabolic disorders (e.g. diabetes, hyperlipidemia, (hypercholesterolemia, hypo-HDL (high-density lipoprotein)-cholesterolemia, hyper-LDL (low-density lipoprotein)-cholesterolemia, hypertriglyceridemia <i>etc</i>.), atherosclerosis, cardiovascular disease, adiposity, metabolic syndrome <i>etc.),</i> hypertension, circulatory diseases <i>etc.</i>

Additionally, the fibrate compound (e.g., chlofibrate) is known as a hypolipidemic agent. It is also resolved that one of the intracellular target proteins of fbrate compounds is PPAR α (see <i>Nature</i>., <u style="single">347</u>, 645 (1990); <i>J. Steroid Biochem. Molec. Biol</i>., <u style="single">51</u>, 157 (1994); <i>Biochemistry</i>., <u style="single">32</u>, 5598 (1993)). From these facts, PPAR α activators are thought to have a hypolipidemic effect, and so they are expected to be useful as agents for prevention and/or treatment of hyperlipidemia <i>etc</i>.

Besides, it has been recently reported that PPAR α possesses anti-obese activity (see WO97/36579). In addition, it was reported that the metabolic stimulation effect of lipid (cholesterol, HDL, LDL and triglyceride <i>etc.)</i> were induced by PPAR α agonists (see <i>J</i>. <i>Lipid Res</i>., <u style="single">39</u>, 17 (1998)). That is, it was reported that they had the elevating effect of high-density lipoprotein (HDL) cholesterol and the lowering effect of low-density lipoprotein (LDL) cholesterol, very low-density lipoprotein (VLDL) cholesterol and triglyceride. It was also reported that composition of fatty acids in blood, hypertension and insulin resistance were improved by administration of bezafibrate which is one of fibrate compounds (see <i>Diabetes</i>., <u style="single">46</u>, 348 (1997)). Therefore, since agonists that activate PPAR α and PPAR α regulators that promote expression of PPAR α protein itself have hypolipidemic effect, they are hopeful agents for the treatment and/or prevention of lipid metabolic disorder (e.g. hyperlipidemia (hypercholesterolemia, hypo-HDL-emia, hyper-LDL-emia, hypertriglyceridemia <i>etc.),</i> atherosclerosis, cardiovascular disease, adiposity, metabolic syndrome <i>etc.),</i> hypertension, circulatory diseases <i>etc.</i>

On the other hand, PPAR δ is sometimes called PPAR β, or it is also called NUC1 in human. Until now, as for activity of PPAR δ, it is disclosed in the specification of WO 9601430 that hNUClB (PPAR subtype whose structure is different from that of human NUCl in one amino acid) inhibited the transcription activities of human PPAR α and thyroid hormone receptor. Recently, it was reported that the compounds, which possessed high affinity to PPAR δ protein and which could activate PPAR δ significantly (agonists) were found out and that they had HDL (high density lipoprotein) cholesterol level-elevating effect and non-HDL cholesterol level-lowering effect(see WO97/28149, WO01/00603, <i>Proc. Natl. Acad. Sci. U.S.A</i>. <u style="single">98</u>, 5306 (2001)). It has been known that macrophage takes up oxidized LDL resulting in foaming and is sedimented in angioendothelium whereby lipid metabolic diseases are induced. Accordingly, it is expected that agonists which are able to activate PPAR δ decrease foam cells due to, for example, an elevating effect for HDL cholesterol and a lowering effect for LDL and are useful, for example, as preventive and/or treating agents for diseases caused by abnormal lipid metabolism (such as hyperlipemia (<i>e</i>.<i>g</i>., hypercholesterolemia, hypo-HDL-emia, hyper-LDL-emia and hypertryglyceridemia), arteriosclerosis, cardiovascular disease, obesity and metabolic syndrome), hypertension, circulatory diseases, <i>etc</i>. Recently, it has been reported that activation of PPARδ promotes oxidation of fatty acid especially in skeletal muscles (see <i>Proc. Natl. Acad Sci. U.S.A</i>., <u style="single">100</u>, 15924 (2003); <i>Cell,</i><u style="single">113</u>, 159 (2003)). They also show that PPARδ agonists are useful for the improvement of abnormal lipid metabolism and for the treatment of obesity.

The activation of PPARδ not only have the effect on lipid metabolic disorder, but also promote the cell differentiation of keratinocytes and is involved in sustain of skin structure as barrier function of organisms. It is observed that the over-proliferative changes of skins occur in PPAR δ-deficient mice treated with TPA (12-<i>O-</i>tetradecanoylphorbol-13-acetate) (see <i>Mol. Cell Biol.,</i><u style="single">20,</u> 5119 (2000)). In addition, it is shown that it has the anti-inflammatory activity on dermal inflammation treated with TPA (see <i>J. Invest. Dermatol.,</i><u style="single">122,</u> 971 (2004)). Therefore, PPAR δ agonists are useful for the preventive and/or therapeutic agent of dermal inflammatory disease (e.g. dermatitis (atopic dermatitis <i>etc.),</i> erythralgia, pruritus <i>etc</i>.) and are expected to have the effect as therapeutic facilitated drug of wound (<i>e</i>.<i>g</i>. burn wound, external wound <i>etc</i>.). Additionally, it is observed that callosal myelin coating disorder occurs in PPAR δ-deficient mice (see <i>Mol. Cell Biol</i>., <u style="single">20</u>, 5119 (2000)) and PPAR δ agonists have possibility of having utility as preventive and/or therapeutic agent of a certain nerve disease.

It is known that, for example, a carboxylic acid derivative represented by formula (A): <chemistry id="chem0001" num="0001"><img file="EP1661879A1_D0001.tif" /></chemistry> wherein L^A, M^A, T^A and X^A are single bond, <i>etc.;</i> W^A is carboxyl; Y^A is an aromatic group or an alicyclic hydrocarbon group; and Z^A and U^A are each an aromatic group, has a PPAR agonistic action and is useful as an improving agent for insulin resistance (cf. WO 02/98840).

As pharmacological test other than ones described in Example, particularly in vivo measurement using animals, for example, the following method is shown. The hypoglycemic effect and hypolipidemic effect of the compound of the present invention can be measured by methods as follows.

Hypoglycemic effect and hypolipidemic effect (1):

Body weight of KKAy/Ta Jcl mice and blood sugar level therein were measured and the mice were grouped using the blood sugar level as an index and assigned. During six days starting from the next day, breeding was conducted using a feed or a powdery feed containing the compound of the present invention. After the repeated administration, body weight and amount of ingested feed were measured and the administered dose was calculated from an average ingested feed amount. Further, in addition to blood sugar level and TG level in plasma, measurement was also conducted for insulin and free fatty acid (NEFA) in blood, GOT and GPT.

It is suggested that the lowering action for blood sugar, insulin in blood, NEFA level or TG level in plasma in the well-fed KKAy/Ta mice has the possibility as an agent for preventive and/or treating for diabetes, hyperlipemia, arteriosclerosis, <i>etc.</i>

Hypoglycemic effect and hypolipidemic effect (2)

Body weight and levels of blood sugar, NEFA, TG and HbAlc were measured in Zucker fa/fa rats (strain name: Crj-[ZUC]-fa/fa) and in lean rats which are normal control animal (strain name: Crj-[ZUC]-lean). The rats were grouped using HbAlc level and body weight as indexes and, as from the next day, the compound of the present invention was repeatedly administered <i>per os.</i> Incidentally, in the control group, a medium was administered.

After starting the repeated administration, an average ingested feed amount was calculated and levels of blood sugar, NEFA, TG and HbAlc were measured. An oral glucose tolerance test (OGTT) was also carried out and an improving action for glucose tolerance was evaluated. In the OGTT, the rats were fasted from the day before the test and, on the next day, 2 g/5mL/kg of a glucose solution was loaded to the rats and then 60 and 120 minutes after loading, blood sugar and blood insulin, NEFA, TG and HbAlc levels and wet liver weight were measured.

It is suggested that the lowering action for blood sugar, insulin in blood, NEFA, HbAlc level or TG level in plasma in the well-fed Zucker fa/fa rats has the possibility as a preventive and/or treating agent for diabetes, hyperlipemia, arteriosclerosis, <i>etc</i>. In addition, it is suggested that action of lowering of blood sugar level upon hunger and action of improving the glucose tolerance in OGTT have the possibility as a preventive and/or treating agent for diabetes.

Hypoglycemic effect and hypolipidemic effect (3):

Cynamolgus monkeys were further subjected to an institutional quarantine and an acclimation in an institute where the test will be carried out. Body weight of the animals was measured, grouping was conducted and a medium or a drug solution containing 3 to 100 mg/kg/day of the compound of the present invention was repeatedly administered into stomach via nose once daily using a nutrition catheter and injection syringe. After the administration, blood was collected and subjected to the above-described hematological tests (measurements of red blood cell count, hematocrit, hemoglobin content, platelet count and white blood cell count) and hematochmical tests (measurements of GOT, GPT, alkaline phosphatase, total protein, nitrogen in urine, creatinine, creatinine kinase, total bilirubin, blood sugar, TC, HDL, LDL and TG) were conducted. Further, blood was collected before starting the administration of the compound of the present invention, after 1, 2 and 4 hour(s) from administration on the 14th day since the start of the administration and after 1, 2 and 3 hour(s) from feeding (ingested for 1 hour) and blood sugar, TC, HDL, LDL and TG were measured.

It is suggested that the lowering effect for plasma TG level, TC level and LDL level in fasted normal cynomolgus monkeys has the possibility as a preventive and/or treating agent for hyperlipemia, arteriosclerosis, <i>etc</i>. That is also confirmed by the fact that a rise in TG after loading with a feed is suppressed. Further, the fact that a rise in blood sugar after loading with a feed is suppressed suggests the possibility as a preventive and/or treating agent for diabetes. Moreover, the fact whether the toxicity change is available is also able to be evaluated from other hemato-biochemical parameters.

Biological Examples

It was confirmed that compounds of the present invention represented by formula (I) have PPAR agonistic activities by the following experiments.

Measurement of PPAR agonistic activities:

(1) Preparation of materials in luciferase assay using human PPAR

The measurement of present invention is the method which has advancement of the measurement accuracy and improvement of the measurement sensitivity in order to evaluate the compounds of the present invention as follows.

That is, as a luciferase gene expression vector under the control of thymidine kinase (TK) promoter, luciferase structural gene was excised from PicaGene Basic Vector 2 (trade name, Toyo Ink Inc., catalogue No. 309-04821), to prepare luciferase gene expression vector pTK-Luc. under the control of TK promoter (-105/+51) as a minimum essential promoter activity from pTKβ having TK promoter (Chrontech Inc., catalogue No. 6179-1). In the upper stream of TK promoter, four times repeated UAS sequence was inserted, which is the response sequence of Gal4 protein, a basic transcription factor in yeast, to construct 4 X UAS-TK-Luc. as reporter gene. The following is the enhancer sequence used (SEQ ID NO:1). SEQ ID NO:1: Enhancer sequence repeating Gal4 protein response sequence 5'-T(CGACGGAGTACTGTCCTCCG)×4 AGCT-3'

A vector was prepared as described hereafter which expresses chimeric receptor protein wherein in carboxyl terminus of yeast Gal4 protein DNA binding domain was fused to ligand binding domain of human PPAR α, γ or δ. That is to say, PicaGene Basic Vector 2 (trade name, Toyo Ink Inc., catalogue No. 309-04821) was used as a basic expression vector, the structural gene was exchanged for that of chimeric receptor protein, while promoter and enhancer domains were kept as they were.

DNA encoding ligand binding domain of human PPAR α, γ or δ fused to DNA encoding Gal4 protein DNA binding domain, the downstream of DNA encoding the 1st to 147th amino acid sequence for fitting their frames and inserted to the downstream of promotor/enhancer domains in PicaGene Basic Vector 2. Here, DNA sequence was aligned as follows, the amino terminus of human PPAR α, γ or δ ligand binding domain was sequenced nuclear translocation signal originated from SV-40 T-antigen, Ala Pro Lys Lys Lys Arg Lys Val Gly (SEQ ID NO:2), to make an expressed chimeric protein localizing intranuclearly. On the other hand, the carboxyl terminus of them was sequenced influenza hemagglutinin epitope, Tyr Pro Tyr Asp Val Pro Asp Tyr Ala (SEQ ID NO:3) and stop codon for translation in this order, to detect an expressed fused protein tagged epitope sequence.

According to the comparison of human PPAR structures described in the literatures by R. Mukherjee <i>et al</i>. (See <i>J</i>. <i>Steroid Biochem</i>. <i>Molec. Biol</i>., <u style="single">51</u>, 157 (1994)), M. E. <i>Green et al</i>., (See <i>Gene Expression.,</i><u style="single">4</u>, 281 (1995)), A. Elbrecht <i>et al</i>. (See <i>Biochem Biophys. Res. Commun</i>., <u style="single">224</u>, 431 (1996)) or A. Schmidt <i>et al</i>. (See Mol. Endocrinology., <u style="single">6</u>, 1634 (1992)), the portion of structural gene used as ligand binding domain of human PPAR α, γ or δ was DNA encoding the following peptide: <ul id="ul0003" list-style="none" compact="compact"><li>human PPAR α ligand binding domain; Ser¹⁶⁷-Tyr⁴⁶⁸</li><li>human PPAR γ ligand binding domain: Ser¹⁷⁶-Tyr⁴⁷⁸</li><li>human PPAR δ ligand binding domain: Ser¹³⁹-Tyr⁴⁴¹</li></ul> (each human PPAR γ1 ligand binding domain and human PPAR γ2 ligand binding domain is Ser²⁰⁴-Tyr⁵⁰⁶ which is identical sequence each other). In order to measure basal level of transcription, an expression vector containing DNA binding domain of Gal4 protein lacking in PPAR ligand binding domain, which is exclusively encoding the 1st to 147th amino acid sequence in Gal4 protein was also prepared.

(2) Luciferase assay using human PPAR α, γ or δ

CV-1 cells used as host cells were cultured by a conventional technique. That is to say, Dulbecco's modified Eagle medium (DMEM) supplemented 10% bovine fetal serum (GIBCO BRL Inc., catalogue No. 26140-061) and 50 U/ ml of penicillin G and 50 µg/ ml of streptomycin sulfate were used to culture CV-1 cells under the atmosphere of 5% carbon dioxide gas at 37°C.

In case of the transfection for introducing DNA, both reporter gene and Gal4-PPAR expression vector, into host cells, 2×10⁶ cells were seeded in a 10 cm dish, and once washed with the medium without serum, followed by addition of the medium (10 ml) thereto. Reporter gene (10 µg), Gal4-PPAR expression vector (0.5 µg) and 50 µl of LipofectAMINE (GIBRO BRL Inc., catalogue No. 18324-012) were well mixed and added to the culture dishes. They were cultured at 37°C for 5 to 6 hours, and thereto was added 10 ml of medium containing 20% of dialyzed bovine fetal serum (GIBRO BRL Inc., catalogue No. 26300-061), and then cultured at 37°C overnight. The cells were dispersed by trypsin treatment, and they were again seeded in 96-well plates in a density of 8000 cells/100 µl of DMEM-10% dialyzed serum/well. Several hours after the cultivation, when cells were attached to the plastic ware, then 100 µl of DMEM-10% dialyzed serum containing the compounds of the present invention, whose concentration is twice as high as the final concentration of them, was added thereto. The culture was settled at 37°C for 42 hours and the cells were dissolved to measure luciferase activity according to manufacturer's instruction.

Carbacyclin activates PPAR δ, and when the data were expressed as relative values (Fold Increase)where the transcription activation degree at a final concentration of 30 µM was defined as 1.

Biological Example:

Lowering action for cholesterol in blood and lipid in blood:

Male mice of seven weeks age (C57BL/6NCrj) was loaded with a high-cholesterol feed (CRF-1 Solid Feed in which 5.5% of peanut oil, 1.5% of cholesterol and 0.5% of cholic acid were mixed; Oriental Bio Service) for six days, then body weight of the rats was measured under fasting and the following various parameter concentrations were measured. Measured items were LDL, HDL, TG value, NEFA and TC value. Depending upon the TC concentrations, each five mice were assigned to one group and the grouping was carried out whereby no imbalance was resulted in mean values of other parameters. From the next day, a compound suspended in a medium (a 0.5% methyl cellulose solution) was compulsorily administered <i>per os</i> once daily for continuous six days and, at the same time, loading with the high cholesterol feed was continued as well. On the next day of the final administration (i.e., on the seventh day from the start of the administration), lipid levels in blood (TG, HDL, LDL, NEFA and TC values) were measured.
