selective inhibitors of leishmanial and trypanosomal dihydrofolate reductase. Compounds were then assayed against the recombinant parasite and human enzymes. Some of the compounds showed good activity. They were also tested against the intact parasites using in vitro assays. Good activity was found against Trypanosoma cruzi, moderate activity against Trypanosoma brucei and Leishmania donovani. Molecular
本文描述了4'-取代和3',4'-二取代的5-苄基-2,4-二氨基嘧啶作为利什曼体和锥虫二氢叶酸还原酶的选择性抑制剂的合成。然后针对重组寄生虫和人类酶测定化合物。一些化合物显示出良好的活性。还使用体外测定法针对完整的寄生虫对它们进行了测试。发现对克鲁斯锥虫的活性良好,对布鲁氏锥虫和多形利什曼原虫的活性中等。进行分子建模以解释结果。发现利什曼酶比活性酶在活性位点具有更广泛的亲脂结合区。结合在口袋中的化合物显示出最高的选择性。
