In previous studies, we identified promising anti-Trypanosoma cruzi cruzain inhibitors based on thiazolylhydrazones. To optimize this series, a number of medicinal chemistry directions were explored and new thiazolylhydrazones and thiosemicarbazones were thus synthesized. Potent cruzain inhibitors were identified, such as thiazolylhydrazones 3b and 3j, which exhibited IC50 of 200–400 nM. Furthermore
在以前的研究中,我们确定了基于噻唑基肼唑酮的有前途的抗克氏锥虫锥虫抑制剂。为了优化该系列,探索了许多药物化学方向,并由此合成了新的噻唑基hydr唑酮和硫代半咔唑酮。已鉴定出强效的克鲁萨因抑制剂,例如噻唑基肼唑3b和3j,其IC 50为200–400 nM。此外,分子对接研究表明与实验得出的结构-活性关系(SAR)数据一致。在这项工作的过程中,先导化合物对克氏锥虫的表鞭毛纲和锥鞭毛纲均表现出体外活性进行鉴定,随后进行体内一般毒性分析。记录了新的SAR,包括连接到噻唑基环上的硫代羰基碳的重要性以及硫代半咔唑酮和噻唑基hydr唑酮之间的直接比较。
