Two triterpenoids (1,4) and two triterpenoid glycosides (2,3) were isolated from the root of Acanthopanax koreanum (Araliaceae). Their structures were identified as impressic acid (1), acankoreoside A (2), 3-epi-betulinic acid 28-O-[alpha-L-rhamnopyranosyl(1 --> 4)-beta-D-glucopyranosyl(1 --> 6)]-beta-D-glucopyranosyl] ester (3), and ursolic acid (4) by physicochemical and spectroscopic methods. Of these compounds, impressic acid (1) exhibited a potent inhibitory activity against NFAT transcription factor (IC50: 12.65 microM).
从五加科植物辽东楤木的根中分离出两种三萜类化合物(1,4)和两种三萜类糖苷(2,3)。通过物理化学和光谱方法确定它们的结构分别为印加酸(1)、刺楤木皂苷A(2)、3-表桦木酸28-O-[α-L-鼠李吡喃糖基(1→4)-β-D-葡萄糖吡喃糖基(1→6)]-β-D-葡萄糖吡喃糖基酯(3)和熊果酸(4)。在这些化合物中,印加酸(1)对NFAT转录因子表现出强效抑制活性(IC50:12.65微摩尔)。
