A series of novel 3-nitro-1H-1,2,4-triazole-based (and in some cases 2-nitro-1H-imidazole-based) amides and sulfonamides were characterized for their in vitro antitrypanosomal and antileishmanial activities as well as mammalian toxicity. Out of 36 compounds tested, 29 (mostly 3-nitro-1H-1,2,4-triazoles) displayed significant activity against Trypanosoma cruzi intracellular amastigotes (IC50 ranging
一系列新型 3-硝基-1 H -1,2,4-三唑基(在某些情况下是 2-硝基-1 H-咪唑基)酰胺和磺胺类药物的体外抗锥虫和抗利什曼原虫活性被表征为以及哺乳动物毒性。在测试的 36 种化合物中,29 种(主要是 3-nitro-1 H -1,2,4-三唑)对克氏锥虫细胞内无鞭毛体(IC 50范围为 28 nM 至 3.72 μM)显示出显着的活性,而对 L6 宿主细胞没有伴随的毒性(选择性 66–2782)。在平行测试中,这些活性化合物中有 23 种比参考药物苯并硝唑更有效(高达 58 倍)。此外,九种具有中等活性的硝基三唑 (0.5 μM ≤ IC 50< 6.0 μM) 对抗布氏罗得西亚锥虫类鞭毛体的活性高 5-31 倍,对抗血流形式的布氏锥虫类鞭毛体,其被设计为过表达减少的烟酰胺腺嘌呤二核苷酸依赖性硝基还原酶。最后,三种硝基三唑对杜氏利什曼原虫的无菌形式显示出中等活性。因此,基于 3-nitro-1
