Problems solved by technology

Clinically, α-interferon and nucleoside drug lamivudine, which have been officially approved by the FDA, can only achieve therapeutic effects to a certain extent, and most patients cannot achieve the purpose of cure. After stopping the treatment, " The "rebound" phenomenon is the most difficult problem for medical workers, so the development of new anti-HBV drugs with high efficiency, low toxicity and no "rebound" poses a challenge to medicinal chemists

Abstract

The invention relates to a medicinal composition for treating hepatitis B. The medicinal composition is made from effective quantity of compounds and chemically and pharmaceutically acceptable carriers. The structure of the compounds is shown as follow. A result of a pharmacological testing comparison between the compounds and positive control lamivudine shows that the compounds have remarkable anti-hepatitis B virus activity, low effective concentration and low cytotoxicity, are remarkably better than the positive control lamivudine and can serve as active ingredients for preparing anti-hepatitis B virus drugs.

Description

technical field [0001] The invention relates to the field of medicine, in particular, the invention relates to a pharmaceutical composition for treating hepatitis B. Background technique [0002] According to relevant statistics, there are about 300 million people in the world who are chronic hepatitis B virus (HBV) carriers, and my country accounts for about half of them. Hepatitis B virus infection has become one of the major diseases affecting human health globally. Since HBV infection can lead to chronic hepatitis, cirrhosis and primary liver cancer, it has become one of the nine major diseases affecting human life. Since the relative risk rate of liver cancer among chronic HBV-infected persons compared with non-carriers is 217, about 2 million people die from liver cirrhosis and liver cancer caused by hepatitis B every year in the world. 250,000 people died from chronic liver disease (cirrhosis and liver cancer) related to hepatitis B. Above-mentioned diseases bring h...
