| Description | EFdA-TP tetraammonium is an influential nucleoside reverse transcriptase (RT) inhibitor that effectively prevents RT-mediated DNA synthesis by acting as an immediate or delayed chain terminator (ICT or DCT). Additionally, EFdA-TP tetraammonium exhibits multiple mechanisms of inhibiting HIV-1 RT[1]. |
| In vitro | EFdA-TP tetraammonium (0.05-10 μM; for 15 min) inhibits RT-catalyzed DNA synthesis as an ICT or DCT[1]. EFdA-TP tetraammonium can block RT as a translocation-defective RT inhibitor that dramatically slows DNA synthesis, acting as a de facto immediate chain terminator. EFdA-TP tetraammonium can function as a delayed chain terminator, allowing incorporation of an additional dNTP before blocking DNA synthesis[1]. |
