(HepG-2 cells), and biological evaluation of 15 hydrazine/hydrazide quinoxaline 1,4-di-N-oxide derivatives against the 3D7 chloroquine sensitive strain and FCR-3 multidrug resistant strain of Plasmodium falciparum and Leishmania infantum (axenic amastigotes). Fourteen of derivatives are novel quinoxaline 1,4-di-N-oxide derivatives. Compounds 18 (3D7 IC50=1.40μM, FCR-3 IC50=2.56μM) and 19 (3D7 IC50=0
我们报告了针对3D7氯喹敏感菌株和FCR-的15种肼/酰肼喹喔啉1,4-二-N-氧化物衍生物的设计(按照计算机模拟ADMET标准),合成,细胞毒性研究(HepG-2细胞)和生物学评估。 3恶性疟原虫和婴儿利什曼原虫(轴突吻合菌)的多药耐药菌株。十四种衍生物是新颖的喹喔啉1,4-二-N-氧化物衍生物。化合物18(3D7 IC50 =1.40μM,FCR-3 IC50 =2.56μM)和19(3D7 IC50 =0.24μM,FCR-3 IC50 =2.8μM)被确定为对恶性疟原虫最具活性,而它们最少具有细胞毒性(CC50值>241μM),选择性最高(SI> 86)。针对婴儿乳杆菌测试的化合物均未被认为具有活性。此外,在喹喔啉1中研究了肼和酰肼结构的功能作用
