摘要

Resveratrol (trans-3,5,4'-trihydroxystilbene. Res) is a naturally occurring antioxidant found in grape berry skins and red wine. It has anti-inflammatory effects. In this study, we examined the effect of Res on the formation of phosphatidic acid (PA) and diglyceride (DG), in human neutrophils stimulated by formyl-methionyl-leucyl-phenylalanine (fMLP) or by phorbol 12-myristate 13-acetate (PMA). We measured the masses of PA and DG by using a nonradioactive method. Our results showed that Res inhibited the formation of PA in a concentration dependent manner with an IC50 value of 42.4 and 60.9 muM in fMLP- and PMA-stimulated cells, respectively Res also suppressed the formation of phosphatidylethanol (PEt), thereby implying inhibition of phospholipase D (PLD) activity. In addition, Res inhibited the formation of both diacylglycerol (DAG) and ether-linked acylglycerol (EAG) induced by fh fMLP and by PMA. Our results suggest that Res inhibition of PLD activity may contribute to its anti-inflammatory effects. (C) 2001 Elsevier Science Inc. All rights reserved. [References: 39]
