2,4-diamino-5-methyl-6-(substituted-phenyl)thiopyrrolo[2,3-d]pyrimidines 4-11 were synthesized as dihydrofolate reductase (DHFR) inhibitors against opportunistic pathogens that afflict patients with AIDS. Synthesis was achieved from 2,4-diamino-5-methypyrrolo[2,3-d]pyrimidine and substituted phenylthiols under modified conditions reported by Gangjee et al. Some of these compounds were potent and selective
2,4-二氨基-5-甲基-6-(取代的苯基)硫代吡咯并[2,3-d]嘧啶4-11被合成为二氢叶酸还原酶(DHFR)抑制剂,用于治疗患有艾滋病的机会病原体。由2,4-二氨基-5-甲基吡咯并[2,3-d]嘧啶和取代的苯硫醇在Gangjee等人报道的改进条件下合成。与哺乳动物的DHFR相比,这些化合物中的某些对弓形虫和鸟分枝杆菌的DHFR均有效且具有选择性。具有1-萘基取代基的化合物11与临床使用的甲氧苄啶相比,对刚地弓形虫DHFR的效力高16倍,并且具有相同的选择性。
