Pyrrole derivatives

TECHNICAL FIELD

[0002] The present invention relates to pyrrole derivatives exhibiting TGF-β inhibitory activity and being useful as fibrosis inhibitors for organs or tissues, a prodrug thereof, and pharmaceutically acceptable salts thereof.

BACKGROUND ART

[0003] Fibrosis of organs or tissues is induced by excessive accumulation of extracellular matrix within the organ, as repair or defenses, when said organ is invaded or damaged by some causes. The extracellular matrix is a substance surrounding the cells of tissues, and representative ones thereof are, for example, fibrinoproteins such as collagen, elastin, etc., complex carbohydrates such as proteoglycan, etc., glycoproteins such as fibronectin, laminin, etc. When the degree of the degeneration of organs, etc. by invasion or injury is not serious, then the organs, etc. can return to normality without any scarring of repair. However, when the degree of the degeneration of organs, etc. by invasion or injury is serious or the degeneration of organs persists, then the fibrosis of scarring of repair will further damage the original function of said organ, etc. And, further fibrosis is induced by said damage. Then, it falls into a vicious cycle thereof. Eventually, there will be caused a deficiency of organs, and at worst, the patient will die.

[0004] TGF-β (Transforming Growth Factor-β) plays an important role in the accumulation of extracellular matrix. When TGF-β is administered to normal animals, there occurred many fibrotic events at various organs of said animals (International Review of Experimental Pathology, 34B: 43-67, 1993). In addition, it was reported that the fibrosis of tissues was observed in transgenic mice which highly express TGF-β (Proc. Natl. Acad. Sci. USA, 92:2572-2576, 1995; Laboratory Investigation, 74:991-1003, 1995).

[0005] TGF-β participates in the fibrosis of tissues in the following manner:

[0006] (1) Acting on cells, the extracellular matrix such as fibronectin (Journal of Biological Chemistry, 262:6443-6446, 1987), collagen (Proc. Natl. Acad. Sci. USA, 85:1105-1108, 1988), proteoglycan (Journal of Biological Chemistry, 263:3039-3045, 1988), etc. is potently produced:

[0007] (2) Decreasing the expression of an enzyme for degrading extracellular matrix (Journal of Biological Chemistry, 263:16999-17005, 1988) and potently promoting the expression of inhibitors of the extracelluar matrix degrading enzyme (Cancer Research, 49:2533-2553, 1989), by which the degradation of extracellular matrix is inhibited:

[0008] (3) Proliferating cells producing extracellular matrix (American Journal of Physiology, 264:F199-F205, 1993).

[0009] Thus, the inhibition of TGF-β is a useful means for inhibiting the accumulation of extracellular matrix. In fact, it is reported that the fibrosis is alleviated by administering antiserum of TGF-β to animal models for fibrosis (Nature, 346:371-374, 1990).

[0143] When Ring Z is pyrrole ring, indole ring, pyrazole ring or imidazole ring, the Friedel-Crafts reaction is preferably carried out by firstly protecting the nitrogen atom at the 1-position with a phenyl-sulfonyl (or toluylsulfonyl) moiety. When the 1-position is protected with phenylsulfonyl moiety, the reaction is carried out, for example, by reacting with phenylsulfonyl chloride, etc. in the presence of a base such as NaH, etc. When Ring Z is a pyrrole ring protected with phenylsulfonyl, the reaction position can be controlled by the kind of a Lewis acid to be used. For example, by using AlCl3, the 3-position is reacted (J. Org. Chem., 48, 3214-3219 (1983)), and by using BF3.OEt2, the 2-position is reacted. After the Friedel-Crafts reaction, the phenylsulfonyl is removed by hydrolysis.

[1487] Experiment 1

[1488] Effects on the Extracellular Matrix Production by TGF-β

[1489] The effect of the compounds of Examples on the production of proteoglycan when TGF-β was added to fibroblast was evaluated.

[1490] NRK-49F cells (rat fibroblast) were cultured in Dulbecco's Modified Eagle Medium (DMEM: manufactured by GIBCO) containing 10% bovine serum, and used in this experiment. The cells were put into a 96-well plate in an amount of 2.5×104 cells/100 μl/well. On the next day, the medium in the plate was exchanged to the DMEM medium containing 3 ng/ml of TGF-β (manufactured by Nacalai Tesque, Inc.), 0.5 μCi/well of [35S]-Na2SO4, and a test compound. Twenty-four hours thereafter, the supernatant was collected, and subjected to SDS-polyacrylamide gel electrophoresis (SDS-PAGE) in a conventional manner. The gel after electrophoresis was dried with a gel drier, and exposed to an imaging plate, which was analyzed with BSA2000 (manufactured by Fuji Photo Film). The radioactivity of proteoglycan to be electrophoresed was measured, and the TGF-β inhibitory rate was calculated by the following equation.

TGF-β Inhibitory rate (%)=(A−B)×100/(A−C)

[1491] A: Radioactivity in the presence of TGF-β without a test compound

[1492] B: Radioactivity in the presence of TGF-β and a test compound

[1493] C: Radioactivity in the absence of TGF-β and a test compound

[1494] The TGF-β inhibitory rates (%) of the test compound at concentrations of 3 μM and 10 pM are shown in Table 1. From the results, the pyrrole derivatives of the present invention inhibit the activity of TGF-β and inhibit the production of proteoglycan in fibroblast.

[1495] Experiment 2

[1496] Evaluation Using Rat Thy-1 Nephritis Model

[1497] The anti-fibrosis activity was evaluated on the compounds of Examples 9, 14, 110, 120 and 136 by using a rat Thy-1 nephritis model, which is an animal model for kidney fibrosis (cf., “Kidney and Dialysis”, vol.31, p.343-347(1991)). Thy-1 is one of the surface antigens of thymocyte.

[1498] Male Wister rats were purchased from Charles River Japan, Inc. at an age of 3-weeks old. After pre-feeding, the animals were used in 10 this experiment when their body weights became about 100 g. The animals were kept in a room being controlled at a temperature of 24±2° C. under a humidity of 55±10%, with an illumination cycle of light on (8:00 to 20:00). The animals were given food (CRF-1, Oriental Yeast Co. Ltd.) and sterilized tap water ad libitum.

[1499] Anti-Thy-1 monoclonal antibody (OX-7, Biosource International Inc.) was administered to the rats at a dose of 50 μg/100 g of body weight at the tail vein. Then, the animals were grouped into the vehicle-treated group (n=8) and the test compound-treated group (n=8) with respect to the body-weight. From the day of administration of anti-Thy-1 monoclonal antibody, a test compound, which was suspended in a 0.5% carboxymethylcellulose (vehicle), was orally administered to the animals once a day at a dose of 15 or 150 mg/kg/day by using an oral sonde. To the vehicle-treated group, a vehicle was administered likewise.

[1500] After the administration for 7 days, the right kidney of the rats was taken out, and the content of hydroxyproline therein, which was an index for organ fibrosis, was measured according to the method of J. F. Woessner, et al. (Arch. Biochem. Biophys. Vol.93 p440 (1961)). That is, the kidney was homogenized, and 500 μL of the suspension was dried, and thereto was added a 4N aqueous sodium hydroxide solution (225 μL). The mixture was heated on a heat block at 100° C. for 15 minutes to hydrolyze proteins, and the mixture was neutralized with a 1.4 M aqueous citric acid solution (275 μL). The mixture was centrifuged at 3000 rpm for 10 minutes at room temperature, and the supernatant was collected as a kidney extract. To the extract were added Chloramine T solution and an Ehrlich solution (which was prepared by adding n-propanol (31 ml) to p-dimethylaminobenzaldehyde (7.5 g), and further slowly adding thereto a 60% perchloric acid (13 mL), and followed by adjusting the volume to 50 ml by distilled water), and the mixture was reacted at 65° C. for 15 minutes. The OD 550 (absorbance at 550 nm) was measured, and the concentration of hydroxyproline was calcurated from the analytical curve of hydroxyproline. The content of hydroxyproline thus obtained was adjusted with respect to the protein amount in the kidney extract.

[1501] The results are shown in Tables 2 to 5. Each value was expressed in average value±standard deviation of 8 animals in each group. As compared with the values of normal rats, the hydroxyproline content in the kideny of rats treated with anti-Thy-1 antibody was increased, and it was found that the extracellular matrix was accumulated in the kidney. In the group treated with the pyrrole derivative of the present invention, the hydroxyproline content was decreased as compared to the vehicle-treated group, and it was found that the pyrrole derivatives of the present invention inhibit the accumulation of extracellular matrix in the kidney.
