Novel papain‐family cathepsin L‐like cysteine protease inhibitors endowed with antitrypanosomal and antimalarial activity were developed, through an optimization study of previously developed inhibitors. In the present work, we studied the structure–activity relationships of these derivatives, with the aim to develop new analogues with a simplified and more synthetically accessible structure and with
通过对先前开发的抑制剂进行优化研究,开发出了具有抗胰锥虫和抗疟疾活性的新型木瓜蛋白酶组织蛋白酶L样半胱氨酸蛋白酶抑制剂。在目前的工作中,我们研究了这些衍生物的结构-活性关系,目的是开发具有简化且可合成的结构更强的抗寄生虫活性的新类似物。通过修饰或什至消除附加在苯并二氮杂pine骨架的C3原子上的侧链,大大简化了模型化合物的结构。此外,在苯二氮卓环和3-溴异恶唑啉部分之间插入一个适当长度的简单亚甲基间隔基。
