Despite the success of potent reverse transcriptase (RT) inhibitors against human immunodeficiency virus type 1 (HIV-1) in combination regimens, the development of drug resistant RTs constitutes a major hurdle for the long-term efficacy of current antiretroviral therapy. Nucleoside β-triphosphate analogs of adenosine and nucleoside reverse transcriptase inhibitors (NRTIs) (3′-azido-2′,3′-dideoxythymidine (AZT), 3′-fluoro-2′,3′-dideoxythymidine (FLT), and 2′,3′-didehydro-2′,3′-dideoxythymidine (d4T)) were synthesized and their inhibitory activities were evaluated against wild-type and multidrug resistant HIV-1 RTs. Adenosine β-triphosphate (1) and AZT β-triphosphate (2) completely inhibited the DNA polymerase activity of wild type, the NRTI multi resistant, and nonnucleoside RT inhibitors (NNRTI) resistant HIV-1 RT at 10 nM, 10 and 100 μM, respectively.
Graphical abstractThe synthesis and inhibitory activities of nucleoside β-triphosphate analogs of adenosine, zidovudine, alovudine, and stavudine against wild-type and multidrug resistant HIV-1 reverse transcriptases are reported.Figure optionsDownload full-size imageDownload as PowerPoint slide
