A series of 2'-substituted derivatives of 9-[2-(phosphonomethoxy)ethyl]guanine (PMEG, 1) have been synthesized and evaluated in vitro for anti-human immunodeficiency virus (HIV) activity in the XTT assay and for anti-herpes activity in the plaque reduction assay. It has been observed that the anti-HIV activity of these derivatives depends on the size and the nature of the substituent as well as the
已经合成了一系列9- [2-(膦酰基甲氧基)乙基]鸟嘌呤(PMEG,1)的2'-取代衍生物,并在XTT分析中体外评估了其抗人免疫缺陷病毒(HIV)的活性以及对斑减少试验中的疱疹活性。已经观察到这些衍生物的抗HIV活性取决于取代基的大小和性质以及在PMEG 2'-位的手性。此外,与疱疹病毒相比,这些化合物通常具有更大的抗HIV活性。这些研究中出现的最有趣的类似物是(R)-2'-(叠氮基甲基)-PMEG [[R] -5]和(R)-2'-乙烯基-PMEG [[R-11]]。前者在CEM细胞中显示出抗HIV活性,IC50为5 microM,细胞毒性(CC50)大于1.4 mM。后者的抗HIV活性IC50为13 microM,CC50大于1.6 mM。此外,我们已经证明用胞嘧啶取代这些2'-取代的PMEG类似物的鸟嘌呤碱基会大大降低抗HIV和抗疱疹的活性。
