A number of methyl derivatives of 9-[2-(phosphonomethoxy)ethyl]guanine (PMEG, 1) have been synthesized and tested in vitro for anti-herpes and anti-human immunodeficiency virus (HIV) activity. Among these analogues, (R)-2'-methyl-PMEG [(R)-3] and 2',2'-dimethyl-PMEG (7) demonstrated potent anti-HIV activity in the XTT assay with EC50 values of 1.0 and 2.6 microM, respectively. The corresponding (S)-2'-methyl-PMEG
已经合成了许多9- [2-(膦甲氧基)乙基]鸟嘌呤的甲基衍生物(PMEG,1),并在体外测试了其抗疱疹和抗人免疫缺陷病毒(HIV)的活性。在这些类似物中,(R)-2'-甲基-PMEG [[R] -3]和2',2'-二甲基-PMEG(7)在XTT分析中显示出有效的抗HIV活性,EC50值为1.0和分别为2.6 microM。发现相应的(S)-2'-甲基-PMEG [(S)-3]对HIV的效力较低。另外,制备9- [3-羟基-2-(膦甲氧基)丙基]鸟嘌呤的(R)和(S)对映异构体(HPMPG,8)用于比较生物学活性,并显示出对疱疹病毒的活性和等效性。 ,但对HIV无效。
