5'-triphosphate 2 and its analogues were synthesized by alkylation of 2-thio-1,N(6)-etheno-2'-deoxyadenosine 5'-monophosphate with the corresponding chloro- or bromo-alkyl halides and converted to the triphosphate. Kinetically, nucleotides 1 and 2 are both competitive inhibitors of reverse transcriptase versus template/primer with K(i)'s of 8.0 and 7.4 microM, respectively, and non-competitive inhibitors versus
我们报告设计,合成和模板类竞争性新型逆转录酶抑制剂(TCRTIs)的活性研究。TCRTI是在我们实验室中合成的一系列基于dATP的模板竞争性DNA聚合酶抑制剂的1,N(6)-乙炔类似物(Moore,BM; Jalluri,R .; Doughty,MB Biochemistry 1996,35,11634)。因此,核苷酸2-(4-叠氮苯酰基)thio-1,N(6)-乙烯基2'-脱氧腺苷5'-三磷酸1,四氟类似物2-(4-叠氮基-2,3,5,6-四氟苯酰基)-1,N(6)-etheno-2'-脱氧腺苷5'-三磷酸2硫代及其类似物是通过2-thio-1,N(6)-etheno-2'-脱氧腺苷5'-单磷酸的烷基化合成的与相应的氯或溴代烷基卤化物一起转化为三磷酸酯。从动力学上来说 核苷酸1和2都是逆转录酶相对于模板/引物的竞争性抑制剂,K(i)分别为8.0和7.4 microM,非竞争性抑制剂相对
