on benznidazole, which displays poor efficacy when administered during the chronic phase of infection. Therefore, the development of new therapeutic options is needed. This study reports on the structural design and synthesis of a new class of anti‐Trypanosoma cruzi thiazolidinones (4 a–p). (2‐[2‐Phenoxy‐1‐(4‐bromophenyl)ethylidene)hydrazono]‐5‐ethylthiazolidin‐4‐one (4 h) and (2‐[2‐phenoxy‐1‐(4‐p
查加斯病的药理治疗是基于苯并硝唑,当在慢性感染阶段给药时,苯并硝唑的疗效较差。因此,需要开发新的治疗选择。这项研究报告了新型抗克鲁斯锥虫噻唑烷酮(4 a – p)的结构设计和合成。(2- [2-苯氧基-1-(4-溴苯基)亚乙基)hydr]] 5-乙基噻唑烷-1-酮(4小时)和(2- [2-苯氧基-1-(4-苯基苯基)亚乙基] hydr] [ ] -5- ethylthiazolidin -4-酮(4升)是最有效的化合物,从而减少epimastigote增殖并且是毒性trypomastigotes在低于10浓度μ中号,尽管它们在200μM的浓度下都没有表现出宿主细胞毒性。噻唑烷酮4 h能够减轻小鼠体内的体外寄生虫负担和血液寄生虫血症,效力与苯硝唑相似。更重要的是,在不表现出小鼠毒性的情况下实现了克氏锥虫感染的减少。关于作用的分子机制,这些噻唑烷酮不抑制克鲁萨因活性,克鲁萨因是主要的锥虫蛋白酶
