    • Safety:

      J05AF10 Wikidata Q418586

    • Target Organs:

      Reverse Transcriptase inhibitor TargetMol T0085L

    • Chemical Class:

      Guanine substituted at the 9 position by a 4-hydroxy-3-(hydroxymethyl)-2-methylidenecyclopentyl group. A synthetic analogue of 2'-deoxyguanosine, it is a nucleoside reverse transcriptase inhibitor wit h selective antiviral activity against hepatitis B virus. Entecavir is phosphorylated intracellularly to the active triphosphate form, which competes with deoxyguanosine triphosphate, the natural subs trate of hepatitis B virus reverse transcriptase, inhibiting every stage of the enzyme's activity, although it has no activity against HIV. It is used for the treatment of chronic hepatitis B. ChEBI CHEBI:473990

      Entecavir(BMS200475; SQ34676) is a guanosine analogue that inhibits reverse transcription, DNA replication and transcription in the viral replication process; oral antiHBV drug.;IC50 value:;Target: AntiHBV drugBoth entecavir and adefovir dipivoxil maintain activity against hepatitis B virus in patients with chronic hepatitis B who are refractory to lamivudine, and both agents are reasonable first-line treatment options. Longer trials involving nucleoside-naive, lamivudine-refractory patients are needed to determine entecavir's optimal treatment duration, long-term safety, and durability of response, including rate of resistance [1]. Entecavir is used to treat chronic hepatitis B. It also helps prevent the hepatitis B virus from multiplying and infecting new liver cells. Entecavir is also indicated for the treatment of chronic hepatitis B in adults with HIV/AIDS infection. However, entecavir is not active against HIV. MedChem Express HY-13623
