Quinoline based antiplasmodial drugs have unequivocally been long-established and continue to inspire the design of new antimalarial agents. Herein, a series of mono- and bisquinoline methanamine derivatives were synthesised through sequential steps; Vilsmeier-Haack, reductive amination, and nucleophilic substitution, and obtained in low to excellent yields. The resulting compounds were investigated
目前有几类抗疟药可用,但毒性问题和耐药性疟原虫的出现降低了它们的整体治疗效率。基于喹啉的抗疟药已明确存在已久,并继续激发新抗疟药的设计。在此,通过连续步骤合成了一系列单喹啉和双喹啉甲胺衍生物;Vilsmeier-Haack、还原胺化和亲核取代,并以低到极好的收率获得。研究了所得化合物对恶性疟原虫3D7 氯喹敏感菌株以及化合物40和59 的体外抗疟原虫活性。成为最有希望的 IC 50值分别为 0.23 和 0.93 µM。最有前途的化合物还通过分子对接协议在计算机上进行了评估,以了解对血红素晶体模型的 0 0 1} 快速生长面的结合亲和力。
