EFdA-TP tetrasodium 

EFdA-TP tetrasodium is a potent nucleoside reverse transcriptase (RT) inhibitor. EFdA-TP tetrasodium inhibits RT-catalyzed DNA synthesis as an effective immediate or delayed chain terminator (ICT or DCT). EFdA-TP tetrasodium inhibits HIV-1 RT with multiple mechanisms^[1]. EFdA-TP (tetrasodium) is a click chemistry reagent, it contains an Alkyne group and can undergo copper-catalyzed azide-alkyne cycloaddition (CuAAc) with molecules containing Azide groups.

EFdA-TP tetrasodium (0.05-10 μM; for 15 min) inhibits RT-catalyzed DNA synthesis as an ICT or DCT^[1].
EFdA-TP tetrasodium can block RT as a translocation-defective RT inhibitor that dramatically slows DNA synthesis, acting as a de facto immediate chain terminator. EFdA-TP tetrasodium can function as a delayed chain terminator, allowing incorporation of an additional dNTP before blocking DNA synthesis^[1].
