Abstract

Two new bufadienolide glycosides (1 and 2) with an A/B trans ring fusion together with nine known compounds (3-11) were isolated from the rhizomes of Helleborus thibetanus. The structures of new compounds were elucidated by extensive spectroscopic analyses in combination with single-crystal X-ray diffraction. The bufadienolides 1 and 3-6 exhibited potent cytotoxic activities against the prostate cancer cells.

摘要

从西藏铁筷子的根茎中分离出两种具有A/B反式环稠合的新蟾蜍二烯内酯苷（1和2）以及九种已知化合物（3-11）。通过广泛的光谱分析结合单晶X射线衍射阐明了新化合物的结构。蟾蜍二烯内酯1和3-6对前列腺癌细胞表现出强大的细胞毒性活性。
