Novel curcumin analogues with α,β-unsaturated ketone moiety and/or α,β-saturated ketone structure were synthesized from curcumin via alkylation at the central carbon and the phenolic hydroxy groups, and hydrogenation of α,β-unsaturated ketone moiety. The antiproliferative activities were tested in five human solid tumor cell lines in vitro. Most of the compounds exhibited increased antiproliferative activities comparing with that of curcumin. Structure–activity relationship (SAR) analysis revealed that the α,β-unsaturated ketone structure was not required for antiproliferative activity of these curcumin analogues. Among these compounds, 1,7-bis(3-methoxy-4-(3-(4-methylpiperazinyl-1-yl)propoxy)phenyl)-4,4-dibenzylheptane-3,5-dione (16f) was the most effective one with IC50 value below 1 µM, which was 9- to 81-fold more potent than curcumin.
以姜黄素为原料,通过中心碳和酚羟基的烷基化以及α,β-不饱和酮基的氢化,合成了具有α,β-不饱和酮基和/或α,β-饱和酮结构的新型姜黄素类似物。体外测试了五种人类实体瘤细胞系的抗增殖活性。与姜黄素相比,大多数化合物的抗增殖活性都有所提高。结构-活性关系(SAR)分析表明,这些姜黄素类似物的抗增殖活性并不需要α、β-不饱和酮结构。在这些化合物中,1,7-双(3-甲氧基-4-(3-(4-甲基哌嗪基-1-基)丙氧基)苯基)-4,4-二苄基庚烷-3,5-二酮(16f)是最有效的化合物,IC50值低于1 µM ,比姜黄素强9-81倍。
