to the detection of five compounds: gallic acid (GA) (1), methyl gallate (2), albiflorin (4), paeoniflorin (5), and pentagalloylglucose (6). Among them, pentagalloylglucose (6) showed cytotoxicity against human breast cancer cells MCF-7 and MDA-MB-231 in vitro with IC50 values of 20.1 and 14.4 μM, respectively. Through the structure–activity relationship of GA, which is an important backbone of pentagalloylglucose
对芍药根的乙酸乙酯部分进行高效液相色谱分析,检测出五种化合物:没食子酸 (GA) ( 1 )、没食子酸甲酯 ( 2 )、白花甙 ( 4 )、芍药甙 ( 5 ) 和五倍子酰葡萄糖(6)。其中,戊酰葡萄糖 ( 6 ) 在体外对人乳腺癌细胞 MCF-7 和 MDA-MB-231 具有细胞毒性,IC 50值分别为 20.1 和 14.4 μM。通过对五没食子酰葡萄糖的重要骨架 GA 的构效关系,我们发现它的三个羟基对其细胞毒性很重要,并且 3- O-甲基没食子酸结构仅对三阴性乳腺癌细胞系有效。此外,通过合成没食子酸的各种酯衍生物来增加其脂质亲和力,从而证实了药效。
