Problems solved by technology

[0003] With the development of modern biology and medicine, the pathogenesis of liver fibrosis and the changes of molecular signals are becoming clearer and clearer. There is no effective treatment, and the FDA has not yet approved drugs and therapies for liver fibrosis, so the development of drugs for liver fibrosis is one of the hot spots in the field of basic research and pharmaceuticals
[0004] Therefore, currently available drugs for the treatment of liver fibrosis remain to be investigated

Embodiment 1

[0066] 1. Experimental method

[0067] The 8-week-old male C57BL / 6 was purchased from Beijing Weitong Lihua Experimental Animal Technology Co., Ltd. through the Experimental Animal Center of Tsinghua University. All mice were housed in a specific pathogen-free barrier at the Experimental Animal Center of Tsinghua University, with free access to water and food. All animal experimental techniques were approved by the Biomedical Analysis Center of Tsinghua University Animal Ethics Committee.

[0068] First, animal models of mouse liver fibrosis with different degrees of severity were constructed, which were called early mouse liver fibrosis animal models ( figure 1 ) and advanced mouse liver fibrosis animal model ( figure 2 ), mice were injected intraperitoneally with 5mL / kg 10% CCL4 (CCL4:olive oil=1:9, v / v) to induce chronic liver injury, twice a week for 4 weeks (early stage) or 10 weeks (late stage). After induction of chronic liver injury, the mice were divided into earl...

Abstract

The present invention provides application of a compound in preparation of a medicine. The medicine is used for treatment of liver fibrosis, and the compound is a compound represented by a formula (I)or a stereoisomer, a tautomer, a nitrogen oxide, a hydrate, a solvate, a metabolite, a pharmaceutically acceptable salt or a prodrug of the compound represented by the formula (I). The compound disclosed by the invention can be used for efficiently treating liver fibrosis diseases, has good absorbability, relatively high biological activity and availability, high solubility and low toxicity, particularly has relatively strong stability in vivo, is not easy to decompose and long in drug effect time, so that an effect of treating liver fibrosis is achieved, and the compound has a good application prospect.

Description

technical field [0001] The present invention relates to the field of medicine. Specifically, the present invention relates to the use of the compound in the preparation of medicines for treating liver fibrosis. Background technique [0002] Hepatic fibrosis is the result of the healing response of the liver in response to various persistent injury factors, and its main features include: activation of hepatic stellate cells, vascularization of hepatic sinusoidal endothelial cells, and collagen deposition. In recent years, liver fibrosis and liver fibrosis-related diseases such as liver cirrhosis and liver cancer have gradually become more harmful, and have become a serious threat to human life. It is reported that there are about 800 million people suffering from liver disease worldwide, and the number of people suffering from liver disease in my country is as high as 300 million. In developed countries, nearly 45% of all deaths are related to fibrotic diseases. If liver f...
