For a fourth approach of quinoxaline N,N′-dioxides as anti-trypanosomatid agents against T. cruzi and Leishmania, we found extremely active derivatives. The present study allows us to state the correct requirements for obtaining optimal in vitro anti-T. cruzi activity. Derivatives possessing electron-withdrawing substituents in the 2-, 3-, 6-, and 7-positions were the most active compounds. With regard
对于喹喔啉N,N'-二氧化物作为抗锥虫和利什曼原虫的抗锥虫病药物的第四种方法,我们发现了活性极高的衍生物。本研究使我们能够阐明获得最佳体外抗T. cruzi活性的正确要求。在2-,3-,6-和7-位具有吸电子取代基的衍生物是活性最高的化合物。考虑到这些特征并考虑到它们的哺乳动物细胞毒性,一些三氟甲基喹喔啉N,N有人提议将二氧化物作为进一步临床研究的候选药物。因此,使用最有前途的衍生物进行了诱变性和体内分析。此外,关于作用机理的研究,已证明线粒体脱氢酶参与了活性最高的衍生物的抗克氏锥虫活性。
