phenyl)‐6H‐pyrido[4,3‐b]carbazoles 11a–b, 5,6‐dimethyl‐9‐hydroxy‐1‐(4‐substituted phenyl)‐6H‐pyrido[4,3‐b]carbazoles 12a, 12c, and their quaternary salts 13a–d were obtained. The four new pyridocarbazole derivatives 12a–c and 13d satisfy the international activity criterion for synthetic compounds, namely an ID50 value lower then 4 μg/mL in preliminary in vitro cytotoxic activity screening against the
从2-(6-甲氧基-1-甲基-9H-咔唑-2-基)乙胺7和4-硝基苯甲酸或4-甲氧基苯甲酸的混合酸酐开始,对应的5,6-二甲基-9-甲氧基-1 -(4-取代苯基)-6H-吡啶并[4,3-b]咔唑11a-b,5,6-二甲基-9-羟基-1-(4-取代苯基)-6H-吡啶并[4,3- b] 获得咔唑 12a、12c 及其季盐 13a-d。四种新的吡啶并咔唑衍生物 12a-c 和 13d 满足合成化合物的国际活性标准,即在针对 A549 细胞系(非小细胞肺癌)的初步体外细胞毒活性筛选中,ID50 值低于 4 μg/mL。
