TECHNICAL FILED OF THE INVENTION

[0001] The present invention relates to a novel carboxylic acid compound useful for prevention or treatment of hyperglycemia, hyperlipemia and inflammatory disease, a salt thereof or a hydrate of them, and to a medicament comprising them.

PRIOR ART

[0002] Diabetes mellitus refers to a durable hyperglycemic condition attributable to the absolute or relative shortage of intrinsic insulin (blood glucose-depressing hormone produced and secreted from Langerhans islet β cells in the pancreas), and in this disease, metabolic abnormalities caused by this condition appear as various morbid states.

[0003] Diabetes mellitus is classified roughly into insulin dependent diabetes mellitus (IDDM) that is type 1 diabetes mellitus, for treatment of which insulin administration is absolutely necessary, non insulin dependent diabetes mellitus (NIDDM) that is type 2 diabetes mellitus, and other diabetes mellitus (secondary diabetes mellitus; diabetes mellitus occurs as one symptom of other diseases).

[0004] In particular, as life-style is modernized, NIDDM is rapidly increased due to overeating and lack of exercise, thus causing a social problem. While IDDM occurs mainly in infants, NIDDM occurs in middle-aged or elderly persons, to account for the majority of diabetes mellitus in Japan. It is said that NIDDM occurs owing to insulin function-suppressing factors (insulin resistance) such as overeating, lack of exercise, obesity and stress in addition to hereditary factors.

[0005] Since excessive intake of calories and obesity resulting from lack of exercise are related to diabetes mellitus as described above, the therapy is based on 3 kinds of therapies, that is, dietary therapy, exercise therapy and chemotherapy.

[0006] However, there are not a few cases where dietary therapy and exercise therapy are hardly to conduct because of an increase in the number of persons of advanced age in this aging society in recent years.

[0007] In chemotherapy of NIDDM, sulfonyl urea (SU) medicines such as Tolbutamide, Chlorpropamide and Tolazamide and Biguanide (BG) medicines such as Metformin hydrochloride and Buformin have been used as oral blood glucose depressants, but the morbid state of NIDDM is characterized by insulin deficiency and insulin resistance, and it cannot be said that the SU medicines stimulating insulin secretion from pancreatic β cells are effective therapeutic medicines for patients with NIDDM condition, where the insulin secretion potential is well but adequate blood glucose control is not achieved in target organs due to insulin registance, thus permitting hyperglycemia. Further, the BG medicines may permit the onset of lactic Acid acidosis, so use of such medicines is limited to a certain extent. Further, these chemicals often caused severe hypoglycemia as a side effect.

[0008] To solve these problems, development of chemicals with a new working mechanism is advancing, and thiazolidine derivatives such as Troglitazone, Pioglitazone and Rosiglitazone are called insulin sensitizers, and these chemicals recently attract attention because they can ameliorate insulin resistance (or enhance the action of insulin) and lower blood glucose without promoting secretion of insulin from the pancreas.

[0009] It has been revealed that these thiazolidine-type chemicals induce differentiation of adipocytes, and exhibit their action via an intranuclear receptor PPARγ (peroxisome proliferator-activated receptor gamma: a transcriptional factor important for differentiation of adipocytes) (J. Biol. Chem., 270, 12953-12956, 1995). By the differentiation of preadipocytes, immature and small adipocytes with less secretion of TNFα, FFA and leptin are increased thus resulting in amelioration of insulin resistance.

[0010] Thiazolidine derivatives such as the above Troglitazone, Pioglitazone and Rosiglitazone also act as agonists for PPARγ, to exhibit the effect of ameliorating insulin resistance.

[0011] Besides PPARγ, PPAR subtypes such as α, β(δ) etc. have been found, any of which regulate expression of genes involved in lipid metabolism. The homology of each subtype among different biological species is higher than the homology of these subtypes in the same species, and with respect to distribution of each subtype in tissues, PPARγ is located substantially in adipose tissues while PPARα occurs mainly in the liver, heart and kidney, and therefore it was considered that each subtype has an independent function. In recent years, it has been revealed that PPARγ mainly mediates lipid anabolism by promoting expression of a group of genes for LPL, acyl-CoA carboxylase, GPDH etc. to convert glucose into lipid and storing the lipid, while PPARα mediates lipid catabolism by regulating expression of a gene group involved in intake of fatty acids into cells and oxidation thereof to decompose lipid.

[0012] Moreover, researches concerning relationships between particular subtypes of PPAR and various diseases have been widely conducted in recent years (J. Med. Chem., 2000, 43(4), 527-550; Trends Cardiovasc. Med., 2000, 10, p238-245).

[0013] As thiazolidine derivatives acting as PPARγ and α dual agonists, compounds disclosed in e.g. JP-A 9-48771 are known.

[0014] Further, some compounds are known as insulin sensitizers having a carboxylic acid moiety in their structure (Current Pharmaceutical Design, 2, No.1, p85-102, 1996; Bioorganic & Medicinal Chemistry Letters, 6, No.17, p2121-2126, 1996; WO200075103; WO9918066; WO9916758).

[0015] However, it has been reported that some chemicals acting as PPARγ agonists cause hepatic damage and thus should be carefully used, so chemicals satisfactory in both therapeutic effects and side effects such as toxicity are still not obtained.

[0016] Further, compounds having a carboxyl group instead of a thiazolidinyl group are merely presented in literatures and not marketed. Further, there is no report showing that such compounds can be used as PPARγ and α dual agonists, and as a matter of course, their γ, α and β(δ) triple agonist action is not known. However, it is also estimated that the toxicity of PPARγ agonists described above is the unique one derived from the thiazolidine moiety, and if a compound exhibiting the above action with a new structure in place of the above structure can be found, the compound can be expected to solve the problem of toxicity, and is thus very useful.

[0017] The conventional chemicals are still unsatisfactory in respect of neutral fat (triglyceride (TG)) related closely to arteriosclerosis.

[0018] Further, the action of PPARβ(δ) to induce differentiation of adipocytes is known (J. Biol. Chem., 274, No. 31, pp. 21920-21925), and by this action, cholesterol levels are reported to be lowered (WO9904815), and if a compound having an agonist action for this subtype can be found, this compound can be expected to exhibit a higher activity than that of the conventional insulin sensitizers and to reduce side effects such as hepatic toxicity.

[0019] Furthermore, as a PRAR receptor ligand, diarylic acid derivatives are disclosed in WO00/64888A and triarylic acid derivatives in WO00/64876A.

[0020] From the foregoing aspects, there is demand for development of excellent chemicals.

EXPERIMENT EXAMPLE 3

[0393] Measurement of Transcriptional Activity

[0394] A GAL4-PPAR LBD chimera expression vector was constructed by ligating human PPAR 167-468 (PPAR), 138-440 (NUC-1) and 174-475 (PPAR) amino acid regions (LBD: Ligand Binding Domain) to a yeast transcriptional factor GAL4 1-147 amino acid region. As the reporter gene, PLAP (Placental Alkaline Phosphatase) was used, and this was ligated downstream of a TK promoter containing a 5-copy GAL4 DNA binding element to construct a vector. As host cells, CV-1 (ATCC CCL-70) was used. That is, CV-1 cells were spread at a density of 5×105 cells on a 35-mm dish and cultured in 10% FCS/DMEM for 24 hours, and using FuGENE 6 transfection reagent, the cells were co-transfected with the GAL4-PPAR LBD expression vector and GAL4 DBD-TK-PLAP expression vector. 24 hours after this transfection, the cells were spread again on a 96-well plate at a density of 1×104/well and further cultured for 24 hours. After 24 hours, the medium was exchanged with DMEM containing 10% FCS, which was previously treated at 65° C. for inactivating intrinsic alkaline phosphatase, and a test compound was added at an arbitrary concentration. The transcriptional activity was determined in terms of PLAP activity secreted 24 hours after addition of the compound, to calculate EC50. The PLAP activity was determined after adding 50 μl assay buffer and 50 μl chemoluminescence substrate to 10 μl culture supernatant and incubating the mixture at room temperature for 1 hour. In this way, transcription activities with respect to PPARα, PPARβ and PPARγ could be determined. Transcription activities with respect to PPARα, PPARβ and PPARγ are shown in Table 2.
