Six novel 2-amino-4-oxo-5-[(substituted phenyl)sulfanyl]pyrrolo[2,3-d]pyrimidines 7-12 were synthesized as potential inhibitors of thymidylate synthase (TS) and as antitumor and/or antibacterial agents. The analogues contain a 5-thio substituent with a phenyl, 4'-chlorophenyl, 3',4'-dichlorophenyl, 4'-nitrophenyl, 3',4'-dimethoxyphenyl, and 2'-naphthyl on the sulfur, and were synthesized from the key
合成了六个新型的2-氨基-4-氧代-5-[(取代的苯基)硫烷基]吡咯并[2,3-d]嘧啶7-12,作为胸苷酸合酶(TS)的潜在抑制剂以及作为抗肿瘤和/或抗菌剂。类似物含有在硫上带有苯基,4'-氯苯基,3',4'-二氯苯基,4'-硝基苯基,3',4'-二甲氧基苯基和2'-萘基的5-硫基取代基,并被合成从关键中间体2-(新戊酰氨基)-4-氧代-6-甲基吡咯并[2,3-d]-嘧啶中除去17。通过碘加成的氧化加成反应,将适当取代的芳基硫醇附加到17的5-位上,乙醇和水的条件下,也会导致2-氨基的脱保护。对化合物进行了抗人,干酪乳杆菌,大肠杆菌,粪链球菌,以及卡氏肺囊虫(pc)TS和人类,大鼠肝脏(rl),pc和弓形虫(tg)DHFR。在侧链(9和10)中带有3',4'-二氯和4'-硝基取代基的非经典类似物比N- [4- [N-[(2-氨基-3,4-二氢-4-氧代-6-喹唑啉基)甲基] -N-丙-2-炔基氨基]苯甲酰基]
