Tenofovir (formerly also known as GS-1278; PMPA; TDF) is an approved anti-HIV drug that blocks reverse transcriptase and hepatitis B virus infections. Tenofovir is an antiretroviral medication used to prevent and treat HIV/AIDS and to treat chronic hepatitis B. Tenofovir reduces the viral cytopathic effect of HIV-1(IIIB), HIV-2(ROD) and HIV(EHO) with EC50 of 1.15 μg/mL, 1.12 μg/mL and 1.05 μg/mL in MT-4 cells. Tenofovir also reduces the viral cytopathic effect of SIV(mac251) , SIV(B670) ,SHIV(89.6) and SHIV(RTSHIV). Tenofovir is the active substance of tenofovir disoproxil which is a prodrug that is used because of its better absorption in the gut.
ln Vitro |
In the MTT experiment, tenofovir exhibits cytotoxic effects on HK-2 cell viability, with IC50 values of 2.77 μM at 48 and 72 hours, respectively. Tenofovir causes HK-2 cells' ATP levels to drop. In HK-2 cells, tenofovir (3.0 to 28.8 μM) elevates protein carbonylation and oxidative stress. Moreover, tenofovir causes HK-2 cells to undergo apoptosis, and this process is brought on by mitochondrial damage[1]. The replication of R5-tropic HIV-1BaL and X4-tropic HIV-1IIIb in activated PBMCs is inhibited by tenofovir and M48U1, when compounded in 0.25% HEC. Additionally, various laboratory strains and patient-derived HIV-1 isolates are inhibited. Infection with R5-tropic HIV-1BaL is inhibited by the synergistic antiretroviral action of M48U1 and tenofovir coupled in 0.25% HEC, and this formulation is not harmful to PBMCs[2].

ln Vivo |
When given to BLT mice (20, 50, 140, or 300 mg/kg), tenofovir Disoproxil Fumarate exhibits dose-dependent efficacy in response to a vaginal HIV challenge in BLT humanized mice. In BLT mice, tenofovir Disoproxil Fumarate (50, 140, or 300 mg/kg) dramatically lowers HIV transmission[3]. In woodchucks with a chronic WHV infection, tenofovir Disoproxil Fumarate (0.5, 1.5, or 5.0 mg/kg/day, po) causes a dose-dependent decrease in serum viremia. The administration of tenofovir Disoproxil Fumarate in the woodchuck model of chronic HBV infection is both safe and effective[4].

Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 0.77 mg/mL (2.68 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 7.7 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 0.77 mg/mL (2.68 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 7.7 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C,1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
