Application:

Entecavir Monohydrate (CAS 209216-23-9) is an oral antiviral drug used in the treatment of Hepatitis B Virus (HBV) infection. Entecavir Monohydrate is a nucleoside analog (more specifically, a guanine analogue) that inhibits reverse transcription, DNA replication and transcription in the vira. It is a new kind of cyclopentyl acyl guanosine anti-Hepatitis B virus drugs with its pharmacological effects similar as Entecavir. It is clinically applied to the treatment of adult Chronic Hepatitis B in which there is active viral replication, increased serum transaminase ALT or active lesions showed from liver histology. Entecavir Monohydrate is a potent and selective inhibitor of HBV, with an EC50 of 3.75 nM in HepG2 cell.  Entecavir is a reverse transcriptase inhibitor. It prevents the Hepatitis B Virus (HBV) from multiplying and reduces the amount of virus in the body.
