hepatocytes. Compounds 5b, 5d, 8h and 8o showed selectivity against L. infantum (IC50 values of 3.89, 2.38, 2.50 and 2.85 μM, respectively). Compounds 4c, 4q, 8a and 8k were the most potent against T. cruzi, exhibiting IC50 values of 6.20, 2.20, 2.30 and 2.20 μM, respectively. Additionally, the most potent anti-T. cruzi compounds showed in vitro efficacies comparable or superior to that of benznidazole. These
发现了一系列高活性杂种作为新型抗寄生虫剂。两个杂环支架(1,2,4-oxadiazole和3-hydroxy-2-oxindole)连接在一起,并且所得的化合物显示出对两种原生动物寄生虫克鲁斯锥虫和婴儿利什曼原虫的胞内羊膜虫的体外活性。使用HFF-1成纤维细胞和HepG2肝细胞评估了它们的细胞毒性。化合物5b,5d,8h和8o显示出对婴儿乳杆菌的选择性(IC 50值分别为3.89、2.38、2.50和2.85μM)。化合物4c,4q,8a和8k对克鲁斯氏锥虫的功效最强,显示出IC 50值分别为6.20、2.20、2.30和2.20μM。此外,最有效的抗-锥虫化合物显示体外效力相当或优于苄硝唑的。这些易于合成的分子代表了新的化学型,用于设计用于南美锥虫病和利什曼病的药物发现的有效和选择性先导化合物。
