Problems solved by technology

However, clinical studies have found that long-term use of large doses of obeticholic acid can cause various adverse reactions such as increased cholesterol levels and decreased high-density lipoprotein levels.
Therefore, in order to avoid these adverse reactions, the dose of obeticholic acid needs to be reduced in clinical application, but it also faces the risk of reduced efficacy

Abstract

The invention belongs to the field of biomedicines, and provides a scheme of combination of an apoptotic inhibitor and Farnesoid XReceptor (FXR) agonist for exerting the synergetic liver protection anti-fibrosis effect. Particularly, the invention relates to therapeutic medication measure for liver fibrosis at an important stage according to chronic liver disease. The invention provides application of combination of FXR agonist and the apoptotic inhibitor in preparation of superior anti-hepatic fibrosis drugs, and particularly the FXR agonist, namely obeticholic acid and the apoptotic inhibitor IDN6556 are selected for use, when the FXR agonist and the apoptotic inhibitor are subjected to low-dosage combination, the glutamic-pyruvic transaminase level in serum can be obviously reduced, thestructural forms and functions of liver cells can be improved, and the fibrotic symptoms is reduced, and due to drug combination, the liver protection effect is obviously superior to that of the single use of the FXR agonist and the apoptotic inhibitor. The invention provides a preparation method of a new superior liver protection anti-fibrosis drug.

Description

technical field [0001] The present invention relates to the field of medicine. The invention relates to the application of a farnesoid X receptor (FXR) agonist in combination with an apoptosis inhibitor in the preparation of an effective anti-fibrosis drug. Specifically, this project uses the FXR agonist obeticholic acid and the apoptosis inhibitor IDN-6556. in CCl 4 In the induced mouse liver fibrosis model, the combination of the two has significantly enhanced anti-fibrosis efficacy. technical background [0002] Liver fibrosis (Liver Fibrosis) refers to a damage repair reaction mainly caused by the deposition of extracellular matrix mainly composed of collagen. Liver fibrosis is the basic stage of the formation of many complex liver diseases in the body. It is an early reversible stage of liver cirrhosis. If it is not treated in time, it will lead to decompensated liver cirrhosis, various terminal liver diseases and related complications. However, there is no specific...
