Five new sesquiterpene lactones, namely vernchinilides A-E (1-5), along with five known compounds, 8 beta-(2-methylacryloyloxy)hirsutinolide 13-O-acetate (6), 8 alpha-(2-methylacryloyloxy)-1beta,4beta-epoxy-1alpha-methoxy-13-O-acetate-10 betaH-germacra-5 E,7(11)-dien-12,6-olide (7), 8 beta-(2-hydroxymethylacryloyloxy)hirsutinolide 13-O-acetate (8), 8 alpha-tigloyloxyhirsutinolide 13-O-acetate ( 9) and vernolide-B (10) were isolated from Vernonia chinensis. The structures of these new compounds were elucidated on the basis of spectral data, especially 2D-NMR techniques. Compounds 2, 5 and 6 exhibited potent cytotoxic activities against P-388 and A-549 tumor cell lines.
从中华斑鸠菊中分离得到了5个新的倍半萜内酯,即斑鸠菊内酯A - E(1 - 5),以及5个已知化合物,8β-(2 - 甲基丙烯酰氧基)水苏内酯13 - O - 乙酸酯(6)、8α-(2 - 甲基丙烯酰氧基)-1β,4β - 环氧 - 1α - 甲氧基 - 13 - O - 乙酸酯 - 10βH - 吉马烯 - 5E,7(11) - 二烯 - 12,6 - 内酯(7)、8β-(2 - 羟甲基丙烯酰氧基)水苏内酯13 - O - 乙酸酯(8)、8α - 惕各酰氧基水苏内酯13 - O - 乙酸酯(9)和斑鸠菊内酯 - B(10)。这些新化合物的结构通过光谱数据,尤其是二维核磁共振技术得以阐明。化合物2、5和6对P - 388和A - 549肿瘤细胞系表现出较强的细胞毒活性。
