The synthesis of potential "combined prodrugs" wherein phosphonoformate or phosphonoacetate was attached to the 5'-position of 2'-deoxyuridine, 2'-deoxythymidine, 5-iodo-2'-deoxyuridine (IDU), 5-(2-chloroethyl)-2'-deoxyuridine (CEDU), or 5-(2-bromovinyl)-2'-deoxyuridine (BVDU) or to the 3'-position of CEDU is described. The antiviral activities of these derivatives and of reference compounds were compared
潜在的“联合前药”的合成,其中膦酸酯或膦酸酯连接到2'-脱氧尿苷,2'-脱氧胸苷,5-碘-2'-脱氧尿苷(IDU),5-(2-氯乙基)的5'位置描述了-2'-脱氧尿苷(CEDU)或5-(2-溴乙烯基)-2'-脱氧尿苷(BVDU)或至CEDU的3'-位置。比较了这些衍生物和参考化合物在Vero,HEp-2和原代兔肾细胞中对1型和2型单纯疱疹病毒(HSV-1和-2)的抗病毒活性。还评估了CEDU和BVDU类似物抗小鼠全身和皮内HSV-1感染的能力。由于只有5-碘,5-(2-溴乙烯基)-,和5-(2-氯乙基)取代的衍生物对疱疹病毒具有抑制作用。此外,类型特异性由5个取代基的性质决定:IDU类似物对HSV-1和-2具有类似的抑制作用,而CEDU和BVDU类似物仅在比HSV-1高得多的浓度下抑制HSV-2复制。在体内,几种衍生物显示出显着的抗病毒活性。但是,没有一个化合物的效价超过其各自的母体化合物
