摘要:
Two series of 7-O-modified chrysin derivatives were prepared from 7-O-carboxymethyl chrysin(2a), 7-O-carboxypropylchrysin(2b) and short-chain alcohols by using 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride(EDCI), N-hydroxybenzotriazole(HOBt) and 4-dimethylamiopryidine(DMAP) as coupling reagents. Taking cisplatin as a reference substance, their anti-proliferative activities in vitro against human gastric carcinoma MGC-803 cells were evaluated by the standard 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) method. The results show that among the compounds tested, hepty 4-(5-hydroxy-4-oxo-2-phenyl-4H-chromen-7-yloxy) acetate(3f) displayed the most potent growth-inhibitory effect on MGC-803 cells with half maximal inhibitory concentration(IC50) value of 3.23 μmol/L. The preliminary mechanism of inhibitory effect of compound 3f was also detected by flow cytometry(FCM), and the compound exerted anti- cancer activity via inducing the apoptosis of MGC-803 cells in a dose dependent manner, which suggested that compound 3f would be a potential anti-cancer agent.
