几种茚并异喹啉在临床试验中已显示出作为抗癌药的希望。将氮原子并入茚并异喹啉支架中提供了有利地调节配体-结合位点相互作用,理化性质和生物活性的可能性。合成了四个氮杂A环茚并异喹啉系列,其中氮原子系统地旋转了1、2、3和4位。对所得化合物进行了测试,以确定拓扑异构酶IB(Top1)酶中毒活性的最佳氮位置。和对人类癌细胞的细胞毒性。4-氮杂化合物最有可能产生具有高Top1抑制活性的衍生物。然而,结构和细胞毒性之间的关系更加复杂,因为内酰胺氮上的侧链强烈影响其效力。最具细胞毒性的氮杂腺苷异喹啉45和46在2或3位具有氮原子,并具有3'-二甲基氨基丙基侧链,并且它们的MGM GI 50值略好于相应的茚并异喹啉64。
