Twenty-six unsymmetrical biphenyls were synthesized and evaluated for cytotoxic activity against DU145, A549, KB and KB-Vin tumor cell lines. Three compounds 27, 35 and 40 showed very potent activity against the HTCL panel with an IC(50) value range of 0.04-3.23 microM. In addition, fourteen active compounds were all more potent against the drug-resistant KB-Vin cell line than the parental KB cell
合成了 26 种不对称联苯并评估了它们对 DU145、A549、KB 和 KB-Vin 肿瘤细胞系的细胞毒活性。三种化合物 27、35 和 40 显示出非常有效的对 HCL 面板的活性,IC(50) 值范围为 0.04-3.23 microM。此外,与亲本 KB 细胞系相比,14 种活性化合物对耐药性 KB-Vin 细胞系的作用更强。初步的 SAR 分析表明,不对称联苯骨架 2,2'-位上的两个庞大的取代基对于体外抗癌活性是必不可少的,因此为开发不对称联苯作为新型抗癌剂提供了良好的起点。
