Herein, we present the design, synthesis and trypanocidal evaluation of sixteen new 1,3,4-thiadiazole derivatives from N-aminobenzyl or N-arylhydrazone series. All derivatives were assayed against the trypomastigote form of Trypanosoma cruzi, showing IC50 values ranging from 3 to 226 μM, and a better trypanocidal profile was demonstrated for the 1,3,4-thiadiazole-N-arylhydrazones (3a-g). In this series
本文中,我们介绍了16种来自N-氨基苄基或N-芳基hydr系列的1,3,4-噻二唑衍生物的设计,合成和杀锥虫性能的评估。所有衍生物均针对锥虫锥虫的锥虫病进行了检测,IC50值为3至226μM,并且1,3,4-噻二唑-N-芳基-(3a-g)的锥虫杀灭特性更好。在这个系列中,结合到肼部分的亚胺亚基的2-吡啶基片段呈现出对锥虫杀虫活性的药效学行为。化合物2a,11a和3e具有出色的活性和出色的选择性指数。化合物2a还具有对抗克鲁氏锥虫的胞内鞭毛体形式的活性。此外,其相应的盐酸盐化合物11a表现出最有前途的特性,产生类似于由泊沙康唑引起的表型变化,泊沙康唑是众所周知的固醇生物合成抑制剂。因此,可以将1,3,4-噻二唑衍生物11a视为开发恰加斯病治疗新药的良好原型。
