The current chemotherapy against Chagas disease is inadequate and insufficient. A series of ten Mannich base-type derivatives have been synthesized to evaluate their in vitro antichagasic activity. After a preliminary screening, compounds 7 and 9 were subjected to in vivo assays in a murine model. Both compounds caused a substantial decrease in parasitemia in the chronic phase, which was an even better
当前针对查加斯病的化学疗法是不足和不足的。已经合成了一系列十个曼尼希碱型衍生物,以评估其体外抗chagasic活性。在初步筛选之后,将化合物7和9在鼠模型中进行体内分析。两种化合物均导致慢性期的寄生虫病大幅减少,这比参考药物苯硝唑的结果更好。另外,化合物9在急性期也显示出更好的抗chagasic活性。此外,还进行了代谢物排泄,对线粒体膜电位的影响以及对超氧化物歧化酶(SOD)的抑制作用的研究,以确定其可能的作用机理。最后,对接研究提出了一种Fe-SOD酶的结合模式,类似于我们先前的系列,验证了我们的设计策略。因此,结果表明应考虑将这些化合物作为抗chachaicant剂进行进一步的临床前评估。
