  Cytotoxic Cholestane Glycosides from the Bulbs of Ornithogalum saundersiae

  摘要：

  Further phytochemical analysis of the bulbs of Ornithogalum saundersiae has yielded two new cytotoxic cholestane triglycosides (1 and 2). The structures of these compounds were determined by spectroscopic analysis, including 2D NMR spectroscopic data, and the results of hydrolytic cleavage. Compounds 1 and 2 and several analogues were evaluated for their cytotoxicity against HL-60 cells.

  虎眼万年青的胆甾醇苷和OSW-1通过线粒体独立信号通路诱导HL-60细胞凋亡。

  摘要：

  一种用于从细胞毒性胆甾苷搜索虎眼万年青灯泡造成的三个新的OSW-1类似物（隔离1 - 3），一个新的胆甾bisdesmoside（4），一个5β-胆甾烷二糖苷（5），和四个新的24（23 →22） -的abeo- -cholestane苷（6 - 9）中，用11节已知的胆甾苷（一起10 - 20），包括OSW-1（11）。1 – 9的结构是根据常规光谱分析和化学证据确定的。不出所料，根据之前的数据，1– 3对HL-60人早幼粒细胞白血病细胞和A549人肺腺癌细胞具有有效的细胞毒活性。此外，检查了OSW-1诱导HL-60细胞凋亡的能力。在用OSW-1处理的HL-60细胞中评估了核染色质的聚集，亚G1细胞的积累，DNA片段化和caspase-3活化，为OSW-1诱导的HL-60细胞凋亡提供了证据。在OSW-1处理的凋亡HL-60细胞中未观察到线粒体膜电位或细胞色素c释放到细胞质中，表明线粒体非依赖性信号通路参与凋亡细胞的死亡。

  Phytochemical examination of the bulbs of Ornithogalum saundersiae led to the isolation of three new acylated cholestane glycosides. Their structures were elucidated, on the basis of the spectroscopic data and chemical evidences, and by comparing them with those of known compounds, as 3beta,16beta,17alpha-trihydroxycholest-5-en-22-one 16-O-beta-D-xylopyranosyl-(1-->3)-(2-O-acetyl-alpha-L-arabinopyranoside), 3beta,16beta,17alpha-trihydroxycholest-5-en-22-one 16-O-(2-O-4-methoxybenzoyl-beta-D-Xylopyranosyl)-(1-->3)-(2-O-acetyl-alpha-L-arabinopyranoside) and 3beta,16beta,17alpha-trihydroxy-cholest-5-en-22-one 16-O-(2-O-3,4-dimethoxybenzoyl-beta-D-xylopyranosyl)-(1-->3)-(2-O-acetyl-alpha-L-arabinopyranoside). Inhibitory activity on cyclic AMP phosphodiesterase of the cholestane glycosides was evaluated.
