(FTIR, NMR, and FABMS). Their biological effects toward a panel of human carcinoma cells, including Hep3B hepatocellular carcinoma, MDAMB‐231 breast carcinoma, and SKHep‐1 hepatoma cells, were investigated; a structure–activity correlation was established with respect to the length of the alkyl chain and the fluorene ring structure. The relationship between the mean potency [log(1/IC50)] and alkyl
在碱性条件下,通过用适当的烷基溴将4,5-二氮杂芴烷基化,制备了一组同源的9,9-二烷基-4,5-二氮杂芴化合物。这些简单的有机化合物的结构已通过光谱技术(FTIR,NMR和FABMS)进行了确认。研究了它们对一组人类癌细胞的生物学效应,包括Hep3B肝细胞癌,MDAMB-231乳腺癌和SKHep-1肝癌细胞。建立了相对于烷基链长度和芴环结构的结构活性相关性。平均效价之间的关系[log(1 / IC 50)]和烷基链长进行了系统研究。结果表明,具有丁基,己基和辛基链的化合物对这三种人类癌细胞系均表现出良好的生长抑制作用,而9,9-二己基-4,5-二氮杂芴在无胸腺裸鼠Hep3B异种移植模型中进一步表现出抗肿瘤活性。 。对于缺乏二氮杂官能团的结构相关的二烷基芴,在临床相关浓度下未观察到体外细胞毒性。
