This invention relates to a novel class of 4,5,6,7-substituted non-nucleoside, non-phosphorylatable pyrrolo[2,3-d]pyrimidines which exhibit both significantly lower levels of cytotoxicity and superior antiviral activity than known nucleoside, non-nucleoside, and non-nucleoside, non-phosphorylatable pyrrolo[2,3-d]pyrimidine derivatives, particularly against human DNA viruses such as cytomegalovirus (HCMV) and herpes simplex virus type 1 (HSV-1). These compounds are represented by the following formula: ##STR1## wherein R.sup.4 is -NH.sub.2 or -NHCH.sub.3 ; R.sup.5 is -CN,-CSNH.sub.2, or -CSeNH.sub.2 ; R.sup.6 is -H or -NH.sub.2 ; and R.sup.7 is selected from the group consisting of aryls and aralkyls having 6 to 30 carbon atoms; aliphatic oxy-hydrocarbyls having 2 to 15 carbon atoms, lacking free hydroxyl groups and further lacking acyl or acyl derivatized groups; and oxy-hydrocarbyls having 6 to 30 carbon atoms, at least one aryl or aralkyl group, and only one oxy-group; with the proviso that if R.sup.5 is -CN and R.sup.6 is -H then R.sup.4 is -NH.sub.2 and R.sup.7 is -CH.sub.2 C.sub.6 H.sub.4 -2-CH.sub.3.
本发明涉及一类新型的4,5,6,7-取代的非核苷、非磷酸化的吡咯并[2,3-d]嘧啶类化合物,其表现出显著较低的细胞毒性和优异的抗病毒活性,特别是对人类DNA病毒如巨细胞病毒(HCMV)和单纯疱疹病毒1型(HSV-1)的作用。这些化合物由以下公式表示:##STR1##其中R.sup.4为-NH.sub.2或-NHCH.sub.3;R.sup.5为-CN、CSNH.sub.2或CSeNH.sub.2;R.sup.6为-H或-NH.sub.2;R.sup.7选自具有6到30个碳原子的芳基和芳基烷基;具有2到15个碳原子、缺乏自由羟基且进一步缺乏酰基或酰基衍生物的脂肪氧烃基;以及具有6到30个碳原子、至少一个芳基或芳基烷基和仅有一个氧基团的氧烃基;但是如果R.sup.5为-CN且R.sup.6为-H,则R.sup.4为-NH.sub.2且R.sup.7为-CH.sub.2C.sub.6H.sub.4-2-CH.sub.3。
