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).
Macaque models of simian or simian/human immunodeficiency virus (SIV or SHIV) infection are critical for the evaluation of antiretroviral (ARV)-based HIV treatment and prevention strategies. However, modelling human oral ARV administration is logistically challenging and fraught by limited adherence. Here
To observe the effects of saxagliptin on the expression of mitogen-activated protein kinase 38 (p38MAPK), nephrin and podocin in renal tissue in type 2 diabetic (T2DM) rats, and to explore the possible mechanism of its renal protection. Forty-eight male Sprague-Dawley

Success in treating hepatitis B virus (HBV) infection with nucleoside analog drugs like lamivudine is limited by the emergence of drug-resistant viral strains upon prolonged therapy. The predominant lamivudine resistance mutations in HBV-infected patients are Met552IIe and Met552Val (Met552Ile/Val), frequently
Emtricitabine (FTC) and lamivudine (3TC), containing an oxathiolane ring with unnatural (-)-stereochemistry, are widely used nucleoside reverse transcriptase inhibitors (NRTIs) in anti-HIV therapy. Treatment with FTC or 3TC primarily selects for the HIV-1 RT M184V/I resistance mutations. Here we provide
Antimicrobial agents and chemotherapy, 37(11), 2285-2292 (1993-11-01)
The pharmacokinetics and metabolism of the potent anti-human immunodeficiency virus and anti-hepatitis B virus compound, (-)-cis-5-fluoro-1-[2-(hydroxymethyl)-1,3-oxathiolan-5-yl] cytosine (FTC), were investigated in male CD rats. Plasma clearance of 10 mg of FTC per kg of body weight was biexponential in rats
