HT29 and H1299 cells with IC50 of 1.76 µM and 3.65 µM, respectively, indicating the mutual contribution of m-methoxy and p-hydroxy groups to the observed cytotoxicities. Moreover, cinnamic acid analogs were less active than the benzoic acid analogs evidenced by higher IC50 values. Furthermore, in cinnamic acid analogs the hydrogenation of double bond to saturated 2-C side chain enhance the cytotoxicities
1,2,3,4,6-五[[O-((3,4,5-三羟基苯甲酰基)]-α,β-D-吡喃葡萄糖(PGG)12的抗氧化活性已有报道,其中游离的OH基团在PGG中似乎对活动至关重要。为了探索基于PGG的化合物作为化学治疗剂并分析PGG中特定OH基团对抗癌活性的贡献,我们设计并合成了27种PGG苯甲酸和肉桂酸类似物。测试了这些类似物对两种人肺(A549和H1299)和两种人结肠(HCT116和HT29)癌细胞系的细胞毒性。化合物12(PGG)对HCT116和A549细胞具有最高的细胞毒性,IC50分别为1.61 µM和3.02 µM。相反,化合物16(1,2,3,4,6-戊基[-O-(4-羟基-3-甲氧基苯甲酰基)]-α,β-D-吡喃葡萄糖,PVG)最有效地杀死HT29和H1299细胞,IC50分别为1.76 µM和3.65 µM,表明间甲氧基和对羟基对观察到的细胞毒性具有相互影响。而且,肉桂酸类似物
