Abstract Background Tenofovir disoproxil fumarate TDF emtricitabine FTC and efavirenz EFV are the three components of the once-daily single tablet regimen Atripla for treatment of HIV-1 infection. Previous cell culture studies have demonstrated that the double combination of tenofovir TFV the parent drug of TDF and FTC were additive to synergistic in their anti-HIV activity which correlated with increased levels of intracellular phosphorylation of both compounds. Results In this study we demonstrated the combinations of TFV FTC TFV EFV FTC EFV and TFV FTC EFV synergistically inhibit HIV replication in cell culture and synergistically inhibit HIV-1 reverse transcriptase RT catalyzed DNA synthesis in biochemical
