The synthesis and biological activity profiling of a large series of diverse pyrrolo[2,3-d]pyrimidine 4'-C-methylribonucleosides bearing an (het)aryl group at position 4 or 5 is reported as well as the synthesis of several phosphoramidate prodrugs. These compounds are 4'-C-methyl derivatives of previously reported cytostatic hetaryl-7-deazapurine ribonucleosides. The synthesis is based on glycosylation
报道了在4或5位带有(杂)芳基的大量不同的吡咯并[2,3-d]嘧啶4'-C-甲基核糖核苷的合成及生物活性分析,以及几种氨基磷酸酯前药的合成。这些化合物是先前报道的抑制细胞生长的杂芳基-7-脱氮嘌呤核糖核苷的4'-C-甲基衍生物。该合成基于卤代7-脱氮嘌呤碱基与1,2-二-O-乙酰基-3,5-二-O-苄基-4-C-甲基-β-d-呋喃核糖的糖基化作用,然后交叉偶联和亲核取代反应。最终化合物显示出低细胞毒性,并且几种衍生物在微摩尔浓度下均具有抗HCV或登革热病毒的抗病毒活性。
