Abstract

The invention discloses applications of protopanaxatriol derivatives or pharmaceutically formable salts thereof and protopanaxatriol or pharmaceutically formable salts of the protopanaxatriol in preparation of medicines for treating a hepatic disease. An in-vitro anti-liver fibrosis cell test proves that these compounds have relatively good anti-liver fibrosis activity, can be used as active components of anti-liver fibrosis medicines, and can be applied widely.

Description

technical field [0001] The present invention relates to the field of medicine, in particular to the application of protopanaxatriol and its derivatives in the preparation of drugs with an anti-hepatic fibrosis effect, and more specifically to the application of protopanaxatriol and its derivatives in the preparation of drugs for the prevention and treatment of liver fibrosis in the application. Background technique [0002] Hepatic fibrosis is caused by various pathogenic factors leading to liver injury, hepatic stellate cells are activated to become myofibroblast-like cells with a strong ability to generate extracellular matrix, and then the production of collagenase inhibitors increases, and collagenase activity decreases. Decrease, the ratio between the production and degradation of extracellular matrix in the liver is unbalanced, and eventually lead to excessive deposition of liver collagen and liver fibrosis. Liver fibrosis continues to deteriorate and lead to liver ci...
