An N-acylhydrazone scaffold has been used to develop new drugs with diverse biological activities, including trypanocidal activity against different strains of Trypanosoma cruzi. However, their mechanism of action is not clear, although in T. cruzi it has been suggested that the enzyme cruzain is involved. The aim in this work was to obtain new N-propionyl-N′-benzeneacylhydrazone derivatives as potential anti-T. cruzi agents and elucidate their potential mechanism of action by a molecular docking analysis and effects on the expression of the cruzain gene. Compounds 9 and 12 were the most active agents against epimastigotes and compound 5 showed better activity than benznidazole in T. cruzi blood trypomastigotes. Additionally, compounds 9 and 12 significantly increase the expression of the cruzain gene. In summary, the in silico and in vitro data presented herein suggest that compound 9 is a cruzain inhibitor.
N-酰肼骨架已被用于开发具有不同生物活性的新药,包括针对不同克鲁斯锥虫株的杀锥虫活性。然而,其作用机制尚不清楚,尽管在克鲁斯锥虫中,有人提出酶克鲁萨因参与其中。这项工作的目的是获得新的N-丙酰-N'-苯酰肼衍生物作为潜在的抗克鲁斯锥虫药物,并通过分子对接分析和克鲁萨因基因表达的影响阐明其潜在的作用机制。化合物9和12是对原头孢虫体最有效的药物,化合物5在克鲁斯锥虫血液锥虫体中显示出比苯硝唑更好的活性。此外,化合物9和12显著增加克鲁萨因基因的表达。总之,本文中提出的计算机模拟和体外数据表明,化合物9是一种克鲁萨因抑制剂。
