Two new cembrane diterpenoids, named populeuphrines A and B ( and ), together with three known analogues (-) were isolated from the resins of . The planar structures and relative configurations of and were elucidated by detailed 1 D and 2 D NMR spectroscopic analyses. The absolute configurations of and were determined by X-ray diffraction analysis and quantum chemical computation. Biological activities of all the isolates against proliferation of human cancer cells and umbilical cord mesenchymal stem cells were evaluated.
从 树脂中分离得到两个新的海松烷二萜类化合物,命名为 populeuphrines A 和 B(和),以及三个已知类似物(-)。通过详细的 1D 和 2D NMR 光谱分析阐明了和的平面结构和相对构型。和的绝对构型通过 X 射线衍射分析和量子化学计算确定。评估了所有分离物对人癌细胞和脐带间充质干细胞增殖的抑制活性。
