Introduction Entecavir monohydrate (BMS200475 monohydrate; SQ34676 monohydrate) is a potent and selective inhibitor of HBV, with an EC50 of 3.75 nM in HepG2 cell.

IC50 & Target EC50：3.75 nM (anti-HBV, HepG2 cell)[1]

In Vitro *Solubility : DMSO : ≥ 50 mg/mL (169.33 mM) H2O : 2.8 mg/mL (9.48 mM; Need ultrasonic and warming) *Preparation : 1mM = 1mg in 3.3865 mL

Entecavir monohydrate (BMS200475 monohydrate; SQ34676 monohydrate) has a EC50 of 3.75 nM against HBV. It is incorporated into the protein primer of HBV and subsequently inhibits the priming step of the . The antiviral activity of BMS-200475 is significantly less against the other RNA and DNA viruses[1]. Entecavir monohydrate is more readily phosphorylated to its active metabolites than other analogs (, , , and ) or . The intracellular half-life of entecavir is 15 h[2].
