Effects of KF-14363 on liver fibrosis in rats with chronic liver injury induced by carbon tetrachloride.

| Abstract |
The present study examined the effects of (1-[(2-thiazolin-2-yl)amino]-acetyl-4-(1,3-dithiol-2-ylidene)-2,3, 4,5- tetrahydro-1H-1-benzazepin-3,5-dione hydrochloride (KF-14363) on liver fibrosis in rats with chronic liver injury induced by carbon tetrachloride (CCl4). Liver injury in male rats was induced by repeated administration of CCl4 at 0.5 ml/kg twice a week. The progression of liver fibrosis was checked in the 4th, 6th, 8th and 10th weeks using the relative amount of hepatic 4-hydroxy proline (4-hyp) to total proteine as an index of hepatic collagen. The relative amount of hepatic 4-hyp in these rats exceeded significantly that in rats not administered CCl4 by the 4th week. This progressed in proportion to the duration of CCl4 administration. In groups concurrently administered KF-14363 at 30 and 100 mg/kg/d from the 5th or 8th week of the CCl4 administration, the relative amount of hepatic 4-hyp was found to be lower in the 10th week than at the start of the KF-14363 administration. The inhibition of liver fibrosis was also observed histopathologically. The concurrently co-administration with CCl4 or KF-14363 at 30 and 100 mg/kg for 2 or 5 weeks inhibited the increases in serum transaminases and alkaline phosphatase induced by CCl4. The results show that KF-14363 inhibits liver fibrosis in a dose dependent fashion in rats with progressive liver injury.
