| Bioactivity | EFdA-TP is a potent nucleoside reverse transcriptase (RT) inhibitor. EFdA-TP inhibits RT-catalyzed DNA synthesis as an effective immediate or delayed chain terminator (ICT or DCT). EFdA-TP inhibits HIV-1 RT with multiple mechanisms[1]. |
| Invitro | EFdA-TP (0.05-10 μM; for 15 min) inhibits RT-catalyzed DNA synthesis as an ICT or DCT[1]. EFdA-TP can block RT as a translocation-defective RT inhibitor that dramatically slows DNA synthesis, acting as a de facto immediate chain terminator. EFdA-TP can function as a delayed chain terminator, allowing incorporation of an additional dNTP before blocking DNA synthesis[1]. |
