- Fibrosis is a condition characterized by excessive deposition of connective tissue proteins involved in abnormal extracellular matrix metabolism in organs such as skin, lung, heart, liver, and kidney.
- liver fibrosis is a disease characterized by excessive deposition of connective tissue proteins such as collagen in the liver.
- connective tissue proteins such as collagen in the liver.
- Various diseases are known as causative diseases of hepatic fibrosis, including diarrhea hepatitis, alcoholic liver disease, schistosomiasis, and the like. In these diseases, connective tissue proteins are gradually contained in the liver parenchyma. As a result, liver function is impaired, eventually leading to cirrhosis (J. Hepatol. 8, 115, 1989).
- cutaneous fibrosis such as scleroderma is a condition characterized by excessive deposition of connective tissue proteins such as collagen in the dermis of the skin.
- connective tissue proteins such as collagen in the dermis of the skin.
- Various skin diseases including chronic inflammation or chronic autoimmunity and skin wounds including mechanical trauma or burn are known as causes of dermal fibrosis (J. Rheumatol. 15, 202, 198 8).
- Pulmonary fibrosis is a condition characterized by excessive deposition of connective tissue proteins such as collagen in the lungs, and interstitial diseases such as drug-induced pneumonia caused by drugs such as anticancer drugs and antibiotics. It is induced by pneumonia and the like (Am. J. Pathol. 259, L159, 1990).

- Production Example 5 was prepared from 1.50 g (7.03 mmol) of 4-aryloxybenzenesulfonyl iocyanate and 1.2 g (7.03 mmol) of 4-cycloanthranilic acid. In the same manner, 1.5 g (yield 53%) of 3- (4-arinoleoxybenzenesnolehoninole) —7-cyclo mouth_2,4 (1H, 3H) —quinazolindione Obtained. From 500 mg (1.27 mmol) of this, 400 mg of the title compound (90% yield) was similarly obtained.
- Human heart chymase was purified according to the method of Urata et al. (J. Biol. Chem., 1990, 265 ⁇ 22348).
- compound 18 inhibited chymase activity in the small intestine by about 80% as compared with the physiological saline-administered group (see Fig. 1). On the other hand, the compound 18 inhibited the chymase activity in the tongue, back skin and feet by about 50%. As described above, it was shown that Compound 18 has a chymase inhibitory action also in vivo.
- the amount of collagen was quantified by measuring the amount of hydroxyproline, an amino acid characteristic of collagen, by HPLC analysis.
- the thickness of the subcutaneous fibrous layer was determined by azan staining of a pathological tissue specimen of the skin, and the area of the fibrous layer was quantified by an image analyzer.
- the pathological tissue specimen was stained with toluidine blue, the number of mast cells stained with cytoplasmic granules was counted, and the cell density per unit area was calculated.
- Skin chymase was extracted by the method already reported (Arch. Dermatol. Res. 290, 553, 1998) and measured in the same manner as in Example 2. Quantification of skin chymase (MMCP-4) mRNA was performed only at 10 weeks of age and analyzed by competitive RT-PCR (Biotechniques 21, 268, 1996).
- the layer thickness and skin chymase activity were quantified and compared with the saline administration group. All parameters were measured in the same manner as in Example 3.
- the thickness of the subcutaneous fibrous layer was analyzed by histopathological analysis. As a result, the compound 18 administration group was about 60% thicker than the physiological saline administration group (see Fig. 7). On the other hand, chymase activity in the compound 18 administration group was 57% of that in the physiological saline administration group (see FIG. 8). As described above, in the test compound administration group, skin chymase activity was suppressed and the skin symptoms were improved in scleroderma model animals.Therefore, chymase inhibitors caused abnormal connective tissue accumulation in various fibrotic diseases. It has been normalized and shown to be useful in preventing or treating fibrosis.
- Example 5 Degradation of hydroxyproline in a bleomycin-induced lung fibrosis model
- bleomycin Nippon Kayaku
- 10-week-old male ICR mice Nippon Charislipa mice
- the lungs were removed and the amount of hydroxyproline, an indicator of the amount of tissue collagen, was quantified by a previously reported method (Anal. Biochem. 19, 249, 1967). .
- the amount of hydroxyprolin was expressed as the amount per lung.
- Intratracheal administration of bleomycin increased the amount of hydroxyproline per lung tissue in a dose-dependent manner to pleomycin (see Figure 9). Each increase rate is 0.0 The values were 1.15 times in the control group and 1.25 times in the 0.08 mg group, both of which were significantly higher than those in the physiological saline group (p ⁇ 0.0 5 and p ⁇ 0.01, Dunnett's test). As described above, it was shown that administration of bleomycin into the trachea causes fibrosis of the lung. In the following tests, the dose of bleomycin was 0.08 mg.
- Example 6 Changes in pulmonary chymase activity in a bleomycin-induced lung fibrosis model
- Pulmonary chymase activity in mice treated with bleomycin was significantly higher than in mice treated with saline (see Figure 10). ).
- the activity of the bleomycin-administered group was about 4.5 times that of the saline-administered group (p ⁇ 0.05, Student's t-test).
- the increase in chymase activity in the pulmonary fibrosis model suggested that chymase was involved in lung fibrosis.
- Example 7 Effect of chymase inhibitor in bleomycin-induced pulmonary fibrosis model
- the effect of the agent (compound 34) was examined.
- the chymase inhibitor is suspended in saline (HPC / saline) containing 0.5% hydroxy propyl eel lulose (HPC / saline), and immediately after administration of bleomycin at a dose of 10 mg / kg or 50 mgZkg. Once a day for 5 days a week for 2 weeks. Similarly, a group to which bleomycin was administered and HPC / saline was administered instead of the test substance was used as a control.
- chymase activity is increased (Example 6), and it is a chymase inhibitor.
- Administration of compound 34 suppressed an increase in the amount of hydroxyproline (Example 7).
- Compound 1 10.0 g was mixed with 22.5 g of microcrystalline cellulose and 2.5 g of magnesium stearate, and the mixture was tableted with a single-shot tableting machine to give 200 per tablet. Tablets 9 mg in diameter and weighing 25 Omg containing mg of compound 1 were prepared.
