Entecavir hydrate Usage And Synthesis
Antiviral drugs Entecavir hydrate 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.
This product is a kind of analogues of guanine nucleoside which has inhibitory on the polymerase of hepatitis b virus (HBV). It can become active triphosphate salts through phosphorylation. The triphosphate salt has a half-life of 15 hours inside a cell. Through completion with the natural substrates of HBV polymerase, guanine nucleoside triphosphate, entecavir triphosphate can suppress all the three types of activities of the virus polymerase (reverse transcriptase):
(1) The initiation of HBV polymerase.
(2) The formation of the negative chain of reverse transcription of the pre-genome.
(3) The synthesis of HBVDNA positive chain.
The inhibition kinetic constant (Ki) of entecavir triphosphate on the HBV DNA polymerase is 0.0012 μM. Entecavir triphosphate has a relative low inhibitory effect on the alpha, beta, and delta DNA polymerase gamma and mitochondria DNA polymerase inside cells with the Ki value being 18 to 160 μM.
