Two new sesquiterpenoids, siegenolides A (1) and B (2), and two known sesquiterpenes 3 and 4 were isolated from Siegesbeckia glabrescens. Their structures were elucidated by spectroscopic analyses, and they were further evaluated for their cytotoxic activities against human cancer cells (MCF-7, AsPC-1, SW480, HCT 116, HepG2, HeLa). Compounds 1-4 showed differential cytotoxic effects on the target cancer cells with IC50 values in the range of 0.9-33.3 μM.
从毛梗豨莶中分离得到两个新的倍半萜类化合物,豨莶内酯A(1)和豨莶内酯B(2),以及两个已知的倍半萜3和4。通过光谱分析确定了它们的结构,并进一步评估了它们对人癌细胞(MCF-7、AsPC-1、SW480、HCT 116、HepG2、HeLa)的细胞毒性活性。化合物1-4对靶癌细胞表现出不同的细胞毒性作用,IC50值在0.9-33.3μM范围内。
