data showed that compound 4 j was able to induce necrosis and apoptosis in trypomastigotes. Analysis by scanning electron microscopy showed that T. cruzi trypomastigote cells treated with compounds 3 h, 3 t, and 4 j at IC50 concentrations promoted changes in the shape, flagella, and surface of the parasite body similar to those observed in benznidazole‐treated cells. The compounds with the highest
恰加斯病和疟疾是两种被忽视的热带病 (NTD),在 149 个国家的热带和亚热带地区流行。由于无症状感染者的移民,恰加斯也出现在欧洲、美国和澳大利亚。在缺乏有效疫苗的情况下,两种疾病的控制都依赖于化疗。然而,寄生虫耐药性的出现正在使目前可用的药物过时。因此,开发新分子至关重要。邻苯二甲酰亚胺、缩氨基硫脲和 1,3-噻唑已被用作支架以获得抗疟原虫和抗克氏锥虫药物。在此,我们展示了 24 种邻苯二甲酰亚胺-缩氨基硫脲 ( 3 a - x ) 和 14 种邻苯二甲酰亚胺 - 噻唑 ( 4 a -n ) 和相应的针对克氏锥虫、恶性疟原虫的生物活性,以及针对哺乳动物细胞系的细胞毒性。其中一些化合物在 RAW 264.7 细胞中以低细胞毒性浓度显示出对T. cruzi 的有效抑制。活性最强的化合物3 t (IC 50 =3.60 μM)、3 h (IC 50 =3.75 μM) 和4 j (IC 50
