A series of new class of 4-(hetero)aryl-2-piperazino quinazolines were synthesized and assessed for in vitro activity against extracellular promastigotes and intracellular amastigotes of Leishmania donovani. Among the compounds evaluated, compound 4bb and 4cb showed the selectivity index (SI) value > 8.03 and 4.21, respectively, which is promising as compared with sodium stilbogluconate (SSG) and pentamidine
合成了一系列新型的4-(杂)芳基-2-哌嗪子喹唑啉类,并评估了其对利什曼原虫的胞外前鞭毛体和胞内变形虫的体外活性。在所评估的化合物中,化合物4bb和4cb的选择性指数(SI)值分别> 8.03和4.21,与司他葡糖酸钠(SSG)和喷他idine的SI分别为6.38和2.07相比,这是有希望的。还测试了合成的化合物在一组哺乳动物细胞系中的抗增殖活性。化合物4aa非常不活泼,而4ab 在抗利什曼测定中几乎没有选择性的蛋白在抗增殖测定中被发现具有显着的活性。
