activity against herpes simplex virus types 1 and 2 in vitro. Certain of the guanine or 8-azaguanine derivatives were good substrates for the viral thymidine kinase and were further converted to triphosphate, but none was a potent inhibitor of the viral DNA polymerase. Nevertheless, one member of this group, (+/-)-9-[[(Z)-2-(hydroxymethyl)cyclopropyl]methyl]guanine (3a), displayed significant antiherpetic
制备了一系列的阿昔洛韦和更昔洛韦类似物,其中通过将环丙烷环或不饱和基团掺入侧链来施加构象约束。另外,合成了几种相关的碱基修饰的化合物。在无序检测中评估了这些无环核苷的酶促磷酸化和DNA聚合酶抑制作用,以及在体外对1型和2型单纯疱疹病毒的抑制活性。某些鸟嘌呤或8-氮杂鸟嘌呤衍生物是病毒胸苷激酶的良好底物,并进一步转化为三磷酸,但没有一种是病毒DNA聚合酶的有效抑制剂。不过,该组的一个成员(+/-)-9-[[((Z)-2-(羟甲基)环丙基]甲基]鸟嘌呤(3a)在体外显示出显着的抗疱疹活性,优于相应的顺式烯烃4a。另一组以(+/-)-9-[[((E)-2-(羟甲基)环丙基]甲基]腺嘌呤为代表的组(17b),尽管显然不能被酶磷酸化,但具有适度的抗病毒活性。本系列讨论了侧链构象和柔性与生物活性之间的关系。
