Abstract
Description
technical field
[0001] The invention relates to a preparation method and application of a class of anti-hepatitis B virus diamine compound, which belongs to the anti-hepatitis B virus compound and its synthesis method and application. Background technique
[0002] Hepatitis B surface antigen, referred to as HBsAg, exists in the outer shell of hepatitis B virus. The detection of HBsAg in serum is one of the early diagnostic indicators of hepatitis B. After hepatitis B virus infection, most people have no clinical manifestations, but HBsAg can be detected in the blood. These people are usually called HBsAg carriers. Hepatitis B e antigen, referred to as HBeAg for short, is the soluble component of HBcAg. HBeAg is associated with the virus Dane particles and hepatitis B virus DNA, and is a serological indicator of active hepatitis B virus replication. Positive serum HBeAg indicates strong infectivity. After the liver cells are invaded by the hepatitis B virus, the hepatitis B...
