Seven previously undescribed 7,20-epoxy-ent-kaurane diterpenoids, isojiangrubesins A-G, along with seventeen known ones, were isolated from the aerial parts of Isodon rubescens. Their structures were characterized on the basis of spectroscopic methods and signal-crystal X-ray diffraction. All of these compounds were evaluated for their in vitro cytotoxicity against five human tumor cell lines (HL-60, SMMC-7721, A-549, MCF-7, and SW480). Four isolates exhibited significant inhibitory ability against all cell lines, with IC values ranging from 0.5 to 6.5 μM; They also strongly inhibited NO production in LPS-stimulated RAW264.7 cells.
从冬凌草的地上部分分离得到了7个新的7,20-环氧-对映-贝壳杉烷二萜类化合物,即异江鲁贝素A-G,以及17个已知化合物。通过光谱方法和单晶X射线衍射对其结构进行了表征。对所有这些化合物进行了体外抗五种人肿瘤细胞系(HL-60、SMMC-7721、A-549、MCF-7和SW480)的细胞毒性评价。4个分离物对所有细胞系均表现出显著的抑制能力,IC值范围为0.5至6.5 μM;它们还强烈抑制LPS刺激的RAW264.7细胞中NO的产生。
