Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0026] The application of teprenone in preparation prevention, treatment fatty liver / steatohepatitis medicine, test method comprises the following steps:

[0027] 1. Establishment and treatment of hepatic steatosis model in vitro

[0028] 1.1. Spread the FL83b mouse liver cell line on a 12-well plate;

[0029] 1.2. Configure high-fat medium (take 50ml as an example): add 200 μM sodium oleate solution and 100 μM Palmitic acid, mix upside down, add 1ml of high-fat ...

Abstract

The invention discloses teprenone (the other name is pentatetraterpenone, and the chemical name is 6,10,14,18-tetramethyl-5,9,13,17-nonadecatetraterpene-2-one). The invention also relates to application of the compound in preparation of medicines for preventing and treating fatty liver/steatohepatitis. In addition to being prepared into capsules, the compound can also be prepared into tablets, powder, granules, oral liquid, injection and other medicine forms. In-vitro test results show that after FL83b cells of an in-vitro fatty degeneration model are stimulated by GGA for 24 hours, lipid droplets in the cells are obviously reduced; and animal experiment results are as follows: 12 weeks after continuous administration of 200mg/kg of GGA to a mouse with fatty liver induced by high fat-cholesterol-fructose diet, the weight gain of the mouse with high fat diet is reduced; meanwhile, the level of serum alanine aminotransferase is remarkably reduced, and the level of cholesterol is remarkably reduced; in addition, inflammation in liver tissues is remarkably relieved, and the fatty degeneration area is remarkably reduced; the serum insulin level is obviously reduced, and the insulin resistance is obviously improved. The medicine is remarkable in curative effect, high in safety, low in price and capable of relieving the economic burden of patients.

Description

technical field [0001] The invention relates to a new application of a compound, in particular to the application of teprenone in the preparation of drugs for the prevention and treatment of fatty liver / steatohepatitis. Background technique [0002] Fatty liver, (called non-alcoholic fatty liver in the past, and now also called metabolism-related fatty liver) is the most common health problem in the world at present, and its incidence rate is increasing year by year. It is estimated that the global prevalence rate reaches 25%. It has become the main cause of liver-related cardiovascular disease morbidity and death. Numerous studies have clearly shown that fatty liver is a metabolic disease and a hepatic manifestation of a systemic metabolic disorder. The 2020 international expert consensus suggests that non-alcoholic fatty liver disease be renamed metabolism-related fatty liver disease. In order to make the appellation consistent, it is uniformly referred to as "fatty live...
