previous studies, the compound 3-(bromopropiophenone) thiosemicarbazone was described as a potent anti-Trypanosoma cruzi and cruzain inhibitor. In view to optimize this activity, 1,3-thiazole core was used as building-block strategy to access new lead generation of anti T. cruzi agents. In this way a series of thiazole derivatives were synthesized and most of these derivatives exhibited antiparasitic
在先前的研究中,化合物3-(溴丙苯甲酮)硫代半碳酰胺被描述为一种有效的抗克鲁斯锥虫和克鲁萨因抑制剂。为了优化此活性,将1,3-噻唑核心用作构建策略,以获取抗T的新先导。克鲁兹代理商。以这种方式合成了一系列噻唑衍生物,并且大多数这些衍生物表现出类似于苯并硝唑(Bzd)的抗寄生虫活性。其中,化合物(1c)和(1g)具有比Bzd更好的选择指数(SI)。另外,化合物显示出对克鲁萨因蛋白酶的抑制活性。通过电子显微镜观察,化合物(1c)处理引起了T型细胞超微结构的不可逆和特殊的形态学改变。克鲁兹(cruzi),表明这类化合物正在杀死寄生虫。
