Quinoxalines belong to the N-containing heterocyclic compounds that stand out as having promising biological activity due to their privileged scaffold. In this work, we report the synthesis, antileishmanial, and antitrypanosomal properties of 46 new 2,3-disubstituted quinoxaline and 40 previously reported derivatives. Among all of the compounds screened for in vitro activity against epimastigotes and
喹喔啉属于含N的杂环化合物,由于其独特的支架,其具有令人鼓舞的生物活性。在这项工作中,我们报告了46种新的2,3-二取代的喹喔啉和40种先前报道的衍生物的合成,抗衰老和抗锥虫性能。在所有筛选的化合物的体外抗epimastigotes和trypomastigotes活性克氏锥虫的前鞭毛体和利什曼原虫亚马孙以及上LLCMK哺乳动物毒性2个从系列细胞和巨噬细胞J774,类似物5,6,7,9,12和13在微摩尔IC 50和EC 50浓度下表现出高活性。选择了十六种喹喔啉衍生物,并在克鲁维斯氏菌和/或亚马逊L. amazonensis amastigotes上进行了评估。最活跃的化合物是图6a-b和图7d-E上的所有形式的演化亚马逊利什曼原虫和克氏锥虫评估了IC 50个值0.1-0.8μM上前鞭毛体和无鞭毛体上epimastigotes 1.4-8.6。化合物5k,12b和13a对克氏锥虫的选择性最高(SI
