N.sup.2 -substituted alkylguanine and N.sup.2 -substituted phenylguanine compounds which prevent recurrent herpes simplex infections are disclosed. By virtue of their ability to inhibit herpes virus thymidine kinase in vivo, such compounds will prevent, reduce the frequency of, or reduce the severity of recurring HSV infections in humans. The N.sup.2 -alkylguanine compounds are of the formula: ##STR1## where R.sub.1 is a normal or branched chain C.sub.n H.sub.2n+1 (where n is 1-12); R.sub.2 is H, 2-deoxyribofuranosyl, (CH.sub.2).sub.n OH (where n is 2-5), CH.sub.2 CH(OH)CH.sub.2 OH, (CH.sub.2).sub.n --COOH (where n is 1-4), CH.sub.2 CH(OH)CH.sub.2 --O--COR.sub.4, (CH.sub.2).sub.n --O--COR.sub.4 (where n is 2-5), or (CH.sub.2).sub.n CO--OR.sub.4 (where n is 1-4); R.sub.4 is CH.sub.3, CH.sub.2 CH.sub.3, CH.sub.2 CH.sub.2 NH.sub.2, CH.sub.2 CH.sub.2 N(C.sub.2 H.sub.5).sub.2 or CH.sub.2 CH.sub.2 CO.sub.2 H; and R.sub.3 is OH, H, Cl or NH.sub.2, or a tautomer or a pharmaceutically acceptable salt thereof. The N.sup.2 -substituted phenylguanine compounds are of similar structure, where R.sub.1 is a phenyl or a phenyl substituted at the 3 and 4 positions with an H, a hydrophobic or electron extracting group, or a CH.sub.2 CH.sub.3.
揭示了防止复发的单纯疱疹病毒感染的N.sup.2-取代烷基鸟嘌呤和N.sup.2-取代苯基鸟嘌呤化合物。由于它们在体内能够抑制单纯疱疹病毒胸苷激酶,这些化合物将防止、减少或减轻人类复发性HSV感染的频率或严重程度。N.sup.2-烷基鸟嘌呤化合物的结构如下:其中R.sub.1是正常或支链C.sub.n H.sub.2n+1(其中n为1-12);R.sub.2是H、2-去氧核糖呋喃糖基、(CH.sub.2).sub.n OH(其中n为2-5)、CH.sub.2 CH(OH)CH.sub.2 OH、(CH.sub.2).sub.n --COOH(其中n为1-4)、CH.sub.2 CH(OH)CH.sub.2 --O--COR.sub.4、(CH.sub.2).sub.n --O--COR.sub.4(其中n为2-5)或(CH.sub.2).sub.n CO--OR.sub.4(其中n为1-4);R.sub.4是CH.sub.3、CH.sub.2 CH.sub.3、CH.sub.2 CH.sub.2 NH.sub.2、CH.sub.2 CH.sub.2 N(C.sub.2 H.sub.5).sub.2或CH.sub.2 CH.sub.2 CO.sub.2 H;R.sub.3是OH、H、Cl或NH.sub.2,或其互变异构体或药学上可接受的盐。N.sup.2-取代苯基鸟嘌呤化合物具有类似结构,其中R.sub.1是苯基或在3和4位置用H、疏水性或电子提取基团或CH.sub.2 CH.sub.3取代的苯基。
