4. Other reasons: primary and secondary liver tumors, liver congestion caused by cardiac insufficiency, certain congenital liver diseases, high-priced intravenous nutrition, etc., can all cause liver damage to varying degrees. The early manifestations of these liver damage are often Elevation of ALT (transaminase) or bilirubin, if the cause is not eliminated, the liver damage will be further aggravated

Abstract

The invention discloses an application of Chukrasone B in the preparation of medicines for preventing and treating liver damage. The pharmacological study on the Chukrasone B shows that the Chukrasone B has a protection effect on mice acute liver injury induced by D-galactosamine (D-GalN) and CC14. Therefore, the Chukrasone B can be used for the preparation of the medicines for preventing and treating liver damage or hepatitis. The application of the Chukrasone B in the medicines for preventing and treating liver damage is disclosed by the invention for the first time. As the skeleton type of the Chukrasone B belongs to a bran-new skeleton type and the Chukrasone B has an unexpected strong activity on liver damage treatment effect, the possibility that other compounds provide revelation does not exist. The Chukrasone B has prominently substantial characteristics and meanwhile has remarkably progressive significance when being used for treating liver damage.

Description

technical field [0001] The present invention relates to Chukrasone B, in particular to Chukrasone B used as medicine for preventing and treating liver damage. technical background [0002] There are multiple reasons for causing liver damage: 1. Viral infection: caused by a variety of hepatitis viruses, with strong infectivity, complex transmission routes, wide epidemic range, and high incidence rate. 2. Drugs or chemical poisons: Many drugs and chemical poisons can cause liver damage, drug-induced hepatitis or toxic hepatitis. 3. Alcoholism: Alcohol damages the liver very seriously. The consequences of the damage include alcoholic hepatitis, alcoholic fatty liver, and alcoholic cirrhosis, mainly due to the toxicity of alcohol (ethanol) and its metabolite acetaldehyde on liver cells. caused by direct damage. 4. Other reasons: primary and secondary liver tumors, liver congestion caused by cardiac insufficiency, certain congenital liver diseases, high-priced intravenous nutri...
