Herein we introduce new compounds as conjugates of arylnicotinic acids with aryl (thio)semicarbazide derivatives. Based on a structure-guided approach, they were designed to possess anti-leishmanial activity through anti-folate mechanism, via targeting Leishmania major pteridine reductase 1 (Lm-PTR1). The in vitro anti-promastigote and anti-amastigote activity were promising for many thiosemicarbazide
在这里,我们介绍新的化合物,作为芳基烟酸与芳基(硫代)氨基脲衍生物的共轭物。基于结构指导的方法,它们被设计成通过靶向利什曼原虫主要蝶啶还原酶1(Lm -PTR1)的抗叶酸机制而具有抗利什曼病的活性。对于许多硫代氨基脲衍生物,其体外抗前鞭毛体和抗鞭毛体的活性是有希望的,并且优于参比米替福星。与参比miltefosine(IC 50)相比,活性最高的化合物8i和8j表现出其抗鞭毛的活性,IC 50值分别为4.2和3.3μM。值7.3)。它们的抗叶酸机制是通过叶酸和亚叶酸逆转这些化合物的抗Leishmanial活性的能力来证实的,与Lm -PTR1抑制剂甲氧苄啶相当。有趣的是,最活性化合物的体外细胞毒性试验显示出比米替福辛更高的选择性指数,强调了它们对哺乳动物细胞的安全性。此外,以Lm -PTR1作为推定目标的对接实验使体外抗利什曼原虫活性合理化。将在硅片预测显示最具活性的化合物具有良好的药代动
