anti-proliferative compound in the series with IC50 values of 1.8 and 2.2 μM toward liver cancer Hep G2 and colon cancer Colon 205 cell lines, respectively. 2,3,3′,4′,5′-Pentamethoxychalcone (1), 3,3′,4,4′,5,5′-hexamethoxychalcone (3), 2,3′,4,4′,5,5′-hexamethoxychalcone (5), 2-hydroxy-3,3′,4′,5′-tetramethoxychalcone (10), 11 and 14 showed significant anti-proliferation actions in Hep G2 and Colon 205
合成了一系列23 3',4',5'-三甲氧基查耳酮类似物,它们对LPS /IFN-γ处理的巨噬细胞中一氧化氮(NO)的抑制作用,并研究了肿瘤细胞的增殖。4-羟基-3,3',4',5'-四甲氧基查尔酮(7),3,4-二羟基-3',4',5'-三甲氧基查尔酮(11),3-羟基-3',4,4 ',5'-四甲氧基查耳酮(14)和3,3',4',5'-四甲氧基查耳酮(15)是产生NO最有效的生长抑制剂,IC 50值为0.3、1.5、1.3和0.3分别为μM。肿瘤细胞增殖测定结果表明,几种化合物对不同的癌细胞系表现出有效的抑制活性。查尔酮15是该系列中最有效的抗增殖化合物,对肝癌Hep G2和结肠癌Colon 205细胞系的IC 50值分别为1.8和2.2μM。2,3,3',4',5'-五甲氧基查耳酮(1),3,3',4,4',5,5'-六甲氧基查耳酮(3),2,3',4,4',5, 5'-六甲氧基查耳酮(5),2-羟基-3
