Abstract

Nine secondary metabolites, including a new cycloartane glucoside, rhizostyloside (1), were isolated from a methanol extract of Rhizophora stylosa leaves through several chromatographic experiments. The structures of the compounds were determined on the basis of NMR spectroscopic (1H and 13C NMR, HSQC, HMBC, 1H-1H COSY, NOESY) and HR-ESI-MS data and by comparison with literature values. Compound 1 exhibited significant cytotoxicity against three human cancer cell lines: KB (epidermoid carcinoma), LU-1 (lung adenocarcinoma), and SK-Mel-2 (melanoma). In addition, 1 strongly activated caspase-3/7 in LU-1 cells.

摘要

通过多次色谱实验，从红海榄叶的甲醇提取物中分离出9种次生代谢产物，包括一种新的环阿尔廷烷糖苷——根柱草苷（1）。这些化合物的结构是根据核磁共振光谱（1H和13C NMR、HSQC、HMBC、1H-1H COSY、NOESY）和高分辨电喷雾电离质谱数据，并与文献值进行比较确定的。化合物1对三种人类癌细胞系表现出显著的细胞毒性：KB（表皮样癌）、LU-1（肺腺癌）和SK-Mel-2（黑色素瘤）。此外，化合物1在LU-1细胞中强烈激活了caspase-3/7。
