kinase readily converts these compounds to their respective monophosphates but not to their corresponding diphosphates. Compound 13a, the (1'R) enantiomer of the bromovinyl analogue 13, was also synthesized, and its potency is comparable to that of the racemate. A lower homologue 14, (1 alpha (E),2 beta, 3 alpha)-1-[2-hydroxy-3-(hydroxymethyl)cyclobutyl]-5- (2-bromovinyl)uracil, was found to be inactive
合成了一系列外消旋的(1 alpha(E),2 beta,3 alpha)-1- [2,3-双(羟甲基)环丁基] -5-(2-卤代乙烯基)尿嘧啶,并在细胞培养中进行了评估。分别为13、15和16的溴乙烯,碘乙烯和氯乙烯类似物都是水痘带状疱疹病毒(VZV)的有效抑制剂,但对人巨细胞病毒(HCMV)和单纯疱疹病毒1和2的复制抑制较小(HSV-1,HSV-2)。13、15和16出色的抗VZV活性,加上它们实际上无法抑制WI-38细胞的生长,表明体外治疗指数很高。VZV胸苷激酶很容易将这些化合物转化为它们各自的单磷酸盐,而不是其相应的二磷酸盐。还合成了溴movinyl类似物13的(1'R)对映异构体化合物13a,它的效价可与外消旋体媲美。发现较低的同系物14(1 alpha(E),2 beta,3 alpha)-1- [2-羟基-3-(羟甲基)环丁基] -5-(2-溴乙烯基)尿嘧啶对VZV无活性,HCMV,HSV-1和HSV-2。
