A polymer-bound α,β-methylene-β-triphosphitylating reagent was synthesized and subjected to reactions with unprotected nucleosides, followed by oxidation, deprotection of cyanoethoxy groups, and acidic cleavage to afford nucleoside 5â²-O-α,β-methylene-β-triphosphates. Among all the compounds, cytidine 5â²-O-α,β-methylene-β-triphosphate inhibited RNase H activity of HIV-1 reverse transcriptase with a Ki value of 225 μM.
合成了一种聚合物键合的α,β-亚甲基-β-三磷酰化试剂,并将其用于与无保护的核苷反应,随后进行氧化、氰乙氧基团的脱保护和酸性裂解,得到了核苷5'-O-α,β-亚甲基-β-三磷酸酯。在所有化合物中,胞苷5'-O-α,β-亚甲基-β-三磷酸酯对HIV-1逆转录酶的RNase H活性具有抑制作用,其Ki值为225μM。
