11-dimethyl-6H-pyrido[4,3-b]carba zole (4b), which display important antitumor properties, were performed either on the side chain or on the intercalating heterocycle. Side chains were introduced by direct substitution of the corresponding chloro derivatives and 6-N-methyl-9-hydroxypyrido[4,3-b]carbazoles analogues were prepared via 9-O-benzoyl-1-chloroellipticines. Evaluation of all new compounds shows no significant
10-[[[3-(二乙基氨基)丙基]氨基] -6-甲基-5H-吡啶基[3',4':4,5]吡咯并[2,3-g] i异喹啉(1b)和1的新修饰对[[[3-(二乙基氨基)丙基]氨基] -9-甲氧基-5,11-二甲基-6H-吡啶基[4,3-b]卡巴唑(4b)进行了重要的抗肿瘤研究,侧链或插入杂环上。通过直接取代相应的氯衍生物引入侧链,并通过9-O-苯甲酰基-1-氯玫瑰树碱制备6-N-甲基-9-羟基吡啶并[4,3-b]咔唑类似物。与模型化合物1b和4b相比,对所有新化合物的评估均显示L1210白血病系统的体外细胞毒性和ILS百分比没有显着增加。
