Novel 4'-hydroxymethyl branched apiosyl nucleosides were synthesized in this study. The introduction of a hydroxymethyl group in the 4'-position was accomplished by a [3,3]-sigmatropic rearrangement. Apiosyl sugar moiety was constructed by sequential ozonolysis and reductions. The natural bases (uracil, thymine, cytosine, and adenine) were efficiently coupled by a classical glycosyl condensation procedure
在这项研究中合成了新型的4'-羟甲基支链的apiosyl核苷。通过[3,3]-σ重排完成在4'-位引入羟甲基。通过顺序的臭氧分解和还原来构建阿糖基糖部分。天然碱(尿嘧啶,胸腺嘧啶,胞嘧啶和腺嘌呤)通过经典的糖基缩合方法(过碱化的碱和TMSOTf)有效地偶联。评估了合成化合物对HIV-1,HSV-1,HSV-2和HCMV的抗病毒活性。化合物18表现出中等的抗HCMV活性(EC50 = 20.1 microg / mL),最高至100 microM都没有细胞毒性。
