* 体外研究： Tenofovir disoproxil fumarate (TDF) serves as a control for CatA-independent prodrug activation. Baseline antiviral activities (mean EC50±standard deviation) obtained in the absence of a protease inhibitors (PI) are determined from 6 independent donors for GS-7340 (EC50=5.3±1.2 nM) and TDF (EC50=2.8±1.1 nM) and are used to calculate fold change EC50s from four independent donors under conditions of PI pretreatment. GS-7340 antiviral activities are similar across all cell types, ranging from 5 to 7 nM, while the CC50 varies from 4.7 to 42 μM for MT-4 and MT-2 cells, respectively. The antiviral activity of TAF is evaluated against a panel of HIV-1 and HIV-2 isolates, including HIV-1 group M subtypes A to G, as well as group N and O isolates. Overall, for the 29 primary HIV-1 isolates tested in PBMCs, TAF EC50s range from 0.1 to 12 nM, with a mean EC50 of 3.5 nM compared to a mean EC50 of 11.8 nM for AZT, which is used as an internal control. For the HIV-2 isolates, the mean EC50s are 1.8 nM for TAF and 6.4 nM for AZT. 体内研究：GS-7340 is an amidate prodrug of Tenofovir with good oral bioavailability and increases plasma stability compared to Tenofovir disoproxil fumarate (TDF) . 产品信息订购：
