摘要: 合成4-(4-羟基-3-甲氧基苯亚甲基)姜黄素(C085),研究其体外抗肿瘤活性和抑制Hsp90作用。以香草醛和姜黄素为原料,微波条件下Knovenagel缩合反应合成了4-(4-羟基-3-甲氧基苯亚甲基)姜黄素(C085)。以姜黄素为对照,MTT法考察目标化合物对人乳腺癌细胞SKBr3、人慢性粒细胞白血病急变细胞株K562、人急性髓系白血病细胞株HL-60、人肝肿瘤细胞株HepG2、小鼠黑色素瘤细胞株B-16、人结肠癌细胞株SW480、人胰腺癌细胞株Bxpc-3、人神经母细胞瘤细胞株SH-SY5Y、人胃癌细胞株MGC80-3的抑制活性。对上述细胞株的IC50值依次为0.51、1.26、2.90、0.81、1.77、1.31、8.22、1.93、7.41 μmol/L,对多种肿瘤细胞抑制活性明显强于Cur。Western Blot结果表明C085明显下调Hsp90的客户蛋白Her2和AKT的表达水平。分子对接分析也支持C085是Hsp90抑制剂。

Abstract: 4-(4-hydroxy-3-methoxyphenyl) methyl curcumin (C085) was synthesized and evaluated for its antitumor activity.C085 was synthesized by Knovenagel condensation. The in vitro antitumor activity of C085 was evaluated by MTT assay against SKBr3,K562,HL-60,HepG2,B-16,SW480,Bxpc-3,SH-SY5Y and MGC80-3 cells. The results showed that C085 inhibited the proliferation of cancer cells (IC50:0.51、1.26、2.90、0.81、1.77、1.31、8.22、1.93、7.41 μmol/L).Western blotting analyses showed that Her2 and AKT degradation were observed upon administration of C085,suggesting this compound exerted activity through Hsp90 inhibition.Molecular docking study also supported C086 as an Hsp90 inhibitor.
