Tenofovir maleate (GS 1278 maleate) 是一种核苷酸逆转录酶 (nucleotide Reverse Transcriptase) 抑制剂，用于治疗HIV和慢性乙型肝炎。

Tenofovir Disoproxil Fumarate is a nucleotide reverse transcriptase inhibitor used in the treatment of HIV and chronic Hepatitis B.

Tenofovir exhibits cytotoxic effects on cell viability in HK-2 cells, with IC 50 values of 9.21 and 2.77 μM at 48 and 72 h in MTT assay, respectively. Tenofovir diminishes ATP levels in HK-2 cells. Tenofovir (3.0 to 28.8 μM) increases oxidative stress and protein carbonylation in HK-2 cells. Furthermore, Tenofovir induces apoptosis in HK-2 cells, and that apoptosis is induced via mitochondrial damage [1]. Tenofovir and M48U1 formulated in 0.25% HEC each inhibits the replication of both R5-tropic HIV-1 BaL and X4-tropic HIV-1 IIIb in activated PBMCs, and inhibits several laboratory strains and patient-derived HIV-1 isolates. The combined formulation of M48U1 and tenofovir in 0.25% HEC exhibits synergistic antiretroviral activity against infection with R5-tropic HIV-1 BaL, and is not toxic to PBMCs [2].

Tenofovir Disoproxil fumarate (20, 50, 140, or 300 mg/kg) administered to BLT mice, shows dose dependent activity during vaginal HIV challenge in BLT humanized mice. Tenofovir Disoproxil fumarate (50, 140, 300 mg/kg) significantly reduces transmission of HIV in BLT mice [3]. Tenofovir Disoproxil fumarate (0.5, 1.5, or 5.0 mg/kg/day, p.o.) induces a dose-dependent decline in serum viremia in woodchucks chronically infected with WHV. Tenofovir Disoproxil fumarate administration is safe and effective in the woodchuck model of chronic HBV infection [4].
