dehydrogenase/trypanothione reductase (GAPDH/TR). These enzymes belong to metabolic pathways that are vital to Trypanosoma brucei and Trypanosoma cruzi, and have thus been considered promising drug targets. The synthesized molecules were characterized for their dual‐target antitrypanosomal profile, both in enzyme assays and in in vitro parasite cultures. The merged derivative 2‐[3‐(3‐dimethylaminopropoxy)‐2‐oxo‐2H
硝呋替莫–氟鸟氨酸联合疗法(NECT)的最新开发已实现了锥虫病治疗的显着改善。作为药物组合的替代方法和克服大多数抗锥虫病药物发现挑战的方法,已经设想了多目标药物设计策略。为了开始验证该假设,我们设计并开发了一系列针对3-磷酸甘油醛脱氢酶/锥虫硫酮还原酶(GAPDH / TR)的醌-香豆素杂种。这些酶属于对布鲁氏锥虫和克氏锥虫至关重要的代谢途径,因此被认为是有前途的药物靶标。合成的分子在酶测定和体外寄生虫培养中均具有双重靶点抗锥虫体特征。合并后的衍生物:2 - [3-(3-二甲氨基丙氧基)-2-氧代-2- ħ -苯并吡喃-7-基]氧基}蒽-1,4-二酮(10)表现出的IC 50为5.4值μ中号对铽GAPDH和伴随ķ我的2.32值μ中号对锝TR。值得注意的是,2- 4- [6- [2-(2-二甲基氨基乙氧基)-2-oxo-2 H-铬n-3-基]苯氧基}蒽-1,4-二酮(化合物6)表现出了卓越的EC
