nitrogen-oxygen bond. The phosphonoalkenyl-substituted compounds 7a-c, 8a-c, 9, 10, and 12 were prepared either by Mitsunobu coupling of alcohols with purine or pyrimidine derivatives or by alternative alkylations of the heterocyclic bases. The (phosphonoalkenyl) oxy derivatives 7d-g, 8d-g, and 11 were synthesized by coupling of alcohols with 9-hydroxypurines or a 1-hydroxypyrimidine under Mitsunobu conditions
合成了嘌呤和嘧啶的一系列膦酰基烯基和(膦酰基烯基)氧基衍生物。这些化合物是首先报道的无环核苷酸,其结合了α,β-不饱和膦酸部分作为磷酸酯模拟物,并且包括其中无环取代基被氮连接至嘌呤的N-9或嘧啶的N-1的化合物。 -碳或氮-氧键。膦酰基烯基取代的化合物7a-c,8a-c,9、10和12是通过醇与嘌呤或嘧啶衍生物的Mitsunobu偶联或通过杂环碱基的替代烷基化来制备的。(膦烯基)氧基衍生物7d-g,8d-g和11是通过在Mitsunobu条件下将醇与9-羟基嘌呤或1-羟基嘧啶偶联而合成的。测试了新型无环核苷酸对1型和2型单纯疱疹(HSV-1和HSV-2),水痘带状疱疹病毒(VZV),巨细胞病毒(CMV),维斯纳病毒和1型人类免疫缺陷病毒(HIV-1)的活性。鸟嘌呤衍生物具有中等至极强的细胞毒性,但腺嘌呤对细胞的毒性较小。在测试浓度下,直链系列中的(Z)异构体对疱疹病毒或HIV-1没有活性。
