Description
GS-7340(Tenofovir alafenamide) is a prodrug of tenofovir (TFV) that more efficiently delivers TFV into lymphoid cells and tissues than TFV disoproxil fumarate.IC50 value:Target: NRTI; HIV reverse transcriptase inhibitorGS-7340 reduces first-pass clearance to be an effective oral prodrug, its permeability and stability were characterized in vitro and detailed pharmacokinetic studies were completed in dogs. GS-7340 showed concentration-dependent permeability through monolayers of caco-2 cells and dose-dependent oral bioavailability in dogs, increasing from 1.7% at 2 mg/kg to 24.7% at 20 mg/kg, suggesting saturable intestinal efflux transport [1]. Significant reductions in plasma HIV-1 RNA from baseline to day 11 were observed for all TAF dose groups compared with placebo (P < 0.01), with a median decrease of 1.08-1.73 log10 copies per milliliter, including a dose-response relationship for viral load decrease up to 25 mg [2].
