Chagas disease continues to be one of the main parasitic diseases in Latin America. Despite the fact that it was
discovered more than 100 years ago, no suitable pharmacologic treatment is available. We report the synthesis of new sulfonamidoquinoline
and sulfonamides derivatives that were evaluated in vitro against two strains of Trypanosoma cruzi
(NINOA and INC-5). Structure-activity relationship analysis indicated that small aromatic and large aromatic substituents
on 4-aminoquinaldine increased trypanocidal activity on INC-5 and NINOA strains, respectively. Additionally, results
show the importance of the sulfonamide group as a scaffold for the development of new anti-T. cruzi agents. Seven sulfonamide
derivatives showed better lytic activity than nifurtimox and beznidazole against both strains of T. cruzi. N-
(biphenyl-4-yl-sulfonyl)-nicotinamide (P-012) was established as the leader of the series for the development of more effective
agents.
恰加斯病仍然是拉丁美洲的主要寄生虫病之一。尽管事实上它是
100 多年前就发现了该病,但目前尚无合适的药物治疗方法。我们报道了新型磺酰胺喹啉的合成
和磺胺衍生物,针对两种克氏锥虫菌株进行了体外评估
(NINOA 和 INC-5)。构效关系分析表明小芳香族和大芳香族取代基
4-氨基喹哪啶分别增加了对 INC-5 和 NINOA 菌株的杀锥虫活性。另外,结果
显示磺酰胺基团作为开发新型抗 T 细胞支架的重要性。克鲁兹特工。七磺酰胺
衍生物对两种克氏锥虫菌株均表现出比硝呋莫司和苯硝唑更好的裂解活性。 N-
(联苯-4-基磺酰基)-烟酰胺(P-012)被确立为该系列的领导者,以开发更有效的
代理。
