Two new sulfated triterpene glycosides, philinopside E (1) and F (2), have been isolated from the sea cucumber Pentacta quadrangularis. Their structures have been established by extensive spectral analysis (NMR and MS) and chemical evidence. Glycoside 1 showed significant cytotoxicity (Ed(50) 0.75-3.50 microg mL(-1)) against ten tumor cell lines.
从四角五角瓜参中分离出了两种新的硫酸化三萜糖苷,即海参皂苷E(1)和F(2)。它们的结构已通过广泛的光谱分析(核磁共振和质谱)及化学证据得以确定。糖苷1对十种肿瘤细胞系显示出显著的细胞毒性(半数有效剂量为0.75 - 3.50微克/毫升)。
