Recently, 4'C-ethynyl nucleoside analogues have been identified as highly potent agents against HIV-1, including several multidrug-resistant strains. In contrast to most known nucleoside inhibitors 4'C-ethynyl nucleoside analogues possess a 3'-hydroxyl function. Here we show that the 5'O-triphosphate of 4'C-ethynyl thymidine gets readily incorporated into a nascent DNA strand by HIV-1 reverse transcriptase
最近,已确定4'C-乙炔基核苷类似物是针对HIV-1的高效药物,其中包括几种耐多药菌株。与大多数已知的核苷抑制剂相反,4'C-乙炔基核苷类似物具有3'-羟基功能。在这里,我们显示4'C-乙炔基胸腺嘧啶的5'O-三磷酸很容易通过HIV-1逆转录酶掺入新生的DNA链中,并显着抑制该酶进一步掺入后链。
