Zusammenfassung
From the rhizomes of Atractylodes lancea, 2-[(2'E)-3',7'-dimethyl-2',6'-octadienyl]-4-methoxy-6-methylphenol (I) was isolated as a new natural product. The compd. showed strong inhibitory effects on 5-lipoxygenase (5-LOX) and cyclooxygenase-1 (COX-1), but exhibited only weak antioxidative activities [IC50 = 0.1 micro M (5-LOX), 2 micro M (COX-1), 9 micro M (PMN/FMLP), 28 micro M (PMN/OZ)]. ...

Zusammenfassung
From the rhizomes of Atractylodes lancea, 2-[(2'E)-3',7'-dimethyl-2',6'-octadienyl]-4-methoxy-6-methylphenol (I) was isolated as a new natural product. The compd. showed strong inhibitory effects on 5-lipoxygenase (5-LOX) and cyclooxygenase-1 (COX-1), but exhibited only weak antioxidative activities [IC50 = 0.1 micro M (5-LOX), 2 micro M (COX-1), 9 micro M (PMN/FMLP), 28 micro M (PMN/OZ)]. Moreover, five new acetylenes were isolated and elucidated as (3Z,5E,11E)-tridecatriene-7,9-diynyl-1-O-(E)-ferulate (II), erythro-(1,3Z,11E)-tridecatriene-7,9-diyne-5,6-diyl diacetate, (1Z)-atractylodin, (1Z)-atractylodinol, (1Z)-acetylatractylodinol plus the known (4E,6E,12E)-tetradecatriene-8,10-diyne-1,3-diyl diacetate. Among the acetylenes, only II showed strong inhibition of 5-LOX and COX-1 activity (IC50 (5-LOX) = 3 micro M, IC50 (COX-1) = 1 micro M). In addn., the fatty acids linoleic acid, oleic acid and palmitic acid with previously established 5-LOX-/COX-1 inhibitory actions were identified as major constituents of the n-hexane ext. and thus seem to contribute to the plant's in vitro activity.
