antileishmanial activity. Interestingly amodiaquine, together with some synthesised derivatives (11, 12, 15, 27, 34), displayed antileishmanial activity in the low micromolar range, although these compounds were also cytotoxic and have a narrow therapeutic window, most of the synthesised compounds proved to be potent antimalarials, a few of them showing a good activity against the chloroquine resistant K1
报道了带有修饰的侧向基本链的新型氨二喹衍生物的合成和研究,所述衍生物为具有抗疟和抗疟疾活性的新药剂。该化合物在体外测试了抗利什曼原虫MHOM / ET / 67 / HU3和2株恶性疟原虫,3D7和K1菌株。所有化合物均显示出复杂的电离曲线。在生理pH下,离子化形式与不带电形式处于平衡状态,而在酸性pH下,所有产物主要以质子化形式存在。抗原生动物的概况表明,所有衍生物都具有抗疟和抗疟疾活性。有趣的是阿莫地喹,一些合成的衍生物(一起11,12,15,27,34),显示在低微摩尔范围antileishmanial活性,尽管这些化合物还细胞毒性和具有窄的治疗窗,大部分合成的化合物的证明是有效的抗疟药,其中的几个显示了针对氯喹良好的活性抗K1菌株。
