Two new diterpenoids, wikstroelide Q (1) and prostratin Q (5), together with three known diterpenoids, pimelea factors P2 (2), P3 (3), and prostratin (4), and five known lignans, (+)-epipioresinol (6), (+)-isolariciresinol (7), (−)-lariciresinol (8), (+)-epi-sesaminone (9), and prestegane B (10), were isolated from the buds of Wikstroemia chamaedaphne Meissn. Their structures were elucidated by a combination of spectroscopic analyses. Compounds 1–10 were evaluated for their cytotoxicities against HL-60, SMMC-7721, A549, MCF-7, SW480, and BEAS-2B cell lines in vitro.
两种新二萜类化合物,荨麻草内酯Q(1)和平卧草内酯Q(5),以及三种已知二萜类化合物,松树因子P2(2)、P3(3)和平卧草内酯(4),再加上五种已知木脂素类化合物,(+)-表松脂酚(6)、(+)-异落叶松树脂酚(7)、(−)-落叶松树脂酚(8)、(+)-表芝麻酚酮(9)和prestegane B(10),从荨麻草(Wikstroemia chamaedaphne Meissn)的芽中分离得到。它们的结构通过综合光谱分析得以确定。化合物1至10在体外对HL-60、SMMC-7721、A549、MCF-7、SW480和BEAS-2B细胞系进行了细胞毒性评估。
