Definitions
- nucleoside drugs reduce hepatitis B virus by inhibiting the synthesis of viral DNA and have no effect on viral RNA.
- Nucleoside drugs can not cure hepatitis B and can only suppress the replication of hepatitis B virus. Therefore, a drug that simultaneously inhibits the novel mechanism of action of viral DNA and RNA is required to cure hepatitis B.
- the newly developed core protein inhibitor can simultaneously inhibit the DNA and RNA of the virus, and the therapeutic effect similar to entecavir can be achieved by using the drug alone.
- hepatitis B In the design of new drugs for the purpose of curing hepatitis B, the mechanism of the newly designed compounds is the same as that of interferon. It is necessary to reactivate the body's own immune system and rely on its own immune system to identify and remove infected liver cells, thus completely curing hepatitis B. Hepatitis B surface antigen and other viral antigens secreted by hepatocytes from patients with chronic hepatitis B interfere with the immune system through signal transduction systems, block the recognition of viruses by immune cells and further limit their antiviral function. In addition, persistent and excessive hepatitis B surface antigens can inactivate the immune system, delete T-cells, and perform functional damage.
- nucleoside drugs can not reduce hepatitis B surface antigen, and it is necessary to design a new mechanism of action, combined with potent nucleoside drugs, and effectively remove hepatitis B surface antigen and viral DNA in the blood, activate and restore itself.
