A number of 4-substituted 7-(ethoxymethyl)- and 7-[(2-methoxyethoxy)methyl]pyrrolo[2,3-d]-pyrimidine-5-carbonitrile and -5-thiocarboxamide derivatives and several 7-substituted 4,6-diaminopyrrolo[2,3-d]pyrimidine-5-carbonitrile, -5-carboxamide, and -5-thiocarboxamide analogs related to the nucleoside antibiotics toyocamycin and sangivamycin were prepared and tested for activity against human cytomegalovirus
一些4-取代的7-(乙氧基甲基)-和7-[(2-甲氧基乙氧基)甲基]吡咯并[2,3-d]-嘧啶-5-腈和-5-硫代羧酰胺衍生物以及几种7-取代的4,制备了与核苷抗生素Toyocamycin和sangivamycin相关的6-二氨基吡咯并[2,3-d]嘧啶-5-腈,-5-羧酰胺和-5-硫代羧酰胺类似物,并测试了其对人巨细胞病毒(HCMV)和单纯疱疹的活性。 1型病毒(HSV-1)。从生物学上讲,细胞培养不能很好地耐受4位修饰,并且几乎在所有情况下均未观察到针对HCMV或HSV-1的活性。此外,没有一种化合物能在体外抑制L1210鼠白血病细胞的生长。与4-取代的化合物形成鲜明对比的是,所有4,6-二氨基5-腈和5-硫代酰胺类似物均具有抗HCMV的活性,而5-羧酰胺是无活性的。相应的4-氨基6-甲基氨基和6-二甲基氨基5-腈类似物对HCMV无活性,从而证明C-4和C-6处的氨基均可能是抗病毒活性
