A series of novel 2,4-diaminopyrimido[4,5-b]indol-6-ols has been synthesized and the in vitro cytotoxic activities were evaluated against four human cancer cell lines originating from solid tumors. An increase in activity was observed when a heteroaromatic ring was annulated on side g of the pyrimido[4,5-b]indole system to give compounds with activities comparable to ellipticine and cisplatin. To understand
合成了一系列新颖的2,4-二氨基嘧啶[4,5-b]吲哚6-醇,并针对四种源自实体瘤的人类癌细胞系评估了体外细胞毒活性。当在嘧啶并[4,5-b]吲哚系统的g侧上环杂芳环时,观察到活性增加,从而得到具有与玫瑰树碱和顺铂相当的活性的化合物。为了了解实验性细胞毒性活性,进行了QSAR研究,结果表明实验性IC和预测IC之间具有很好的线性关系(50)。
