Description

Biochem/physiol Actions

Emtricitabine ((-)-FTC) is an orally active, non-cytotoxic (>100 μM/PBM, CEM, Vero, MT-4), potent nucleoside reverse transcriptase inhibitor (NRTI) against HIV type 1/2 (HIV-1 IC50/culture = 8 nM/PBM (LAV-1), 9 nM/CEM (LAV-1); HIV-2 IC50/culture = 0.7 nM/PBM (ROD2), 100 nM/CEM (Zy)), hepatitis B, as well as simian and feline immunodeficiency viruses. Emtricitabine is activated via 2′-deoxycytidine kinase-mediated phosphorylation to (-)-FTC-5′-triphosphate that inhibits viral reverse transcriptase in a dCTP-competitive manner (HIV-1 Ki = 2.9 μM).
