In this study, we synthesized novel 4′‐hydroxymethyl branched thioapiosyl nucleosides. The thioapiosyl sugar moiety was constructed using sequential ozonolysis and reduction. The natural bases (uracil, thymine, cytosine, and adenine) were efficiently coupled using the Vorbrüggen glycosyl condensation procedure (persilyated base and TMSOTf). The antiviral activities of the synthesized compounds were
在这项研究中,我们合成了新的 4'-羟甲基支链硫硫磷核苷。使用连续的臭氧分解和还原构建硫辛基糖部分。天然碱基(尿嘧啶、胸腺嘧啶、胞嘧啶和腺嘌呤)使用 Vorbrüggen 糖基缩合程序(过甲硅烷基化碱基和 TMSOTf)有效偶联。对合成化合物的抗病毒活性进行了评估,以对抗 HIV-1、HSV-1、HSV-2 和 HCMV。化合物 19 显示出中等的抗 HIV 活性(EC50 = 19.3 μg/mL),而在高达 100 μM 时没有表现出任何细胞毒性。
