Abstract

Neutrophils metabolize arachidonic acid through the liposygenase pathway to 5-hydroxy-6,8,11,14-eicosatetrenoic acid (5-HETE) and 5,12-dihydroxy-6,8,10,14-eicosatraenoic acid (5,12 diHETE). 5-HETE and 5,12diHETE are potent chemotactic agents and are thought to have important roles in the inflammatory response. In this study we demonstrate the sulfasalazine, at concentrations found in the stool of patients being treated for ulcerative colitis, blocks the synthesis of both 5-HETE and 5,12 diHETE by human neutrophils. A sulfasalazine metabolite, 5-aminosalicylate, also blocks the synthesis of 5,12 diHETE.

摘要

中性粒细胞通过脂氧合酶途径将花生四烯酸代谢为5-羟基-6,8,11,14-二十碳四烯酸(5-HETE)和5,12-二羟基-6,8,10,14-二十碳四烯酸(5,12-二HETE)。5-HETE和5,12-二HETE是强效趋化剂,被认为在炎症反应中起重要作用。在本研究中,我们证明,柳氮磺胺吡啶在溃疡性结肠炎患者粪便中发现的浓度下,可阻断人中性粒细胞合成5-HETE和5,12-二HETE。柳氮磺胺吡啶的一种代谢产物5-氨基水杨酸也可阻断5,12-二HETE的合成。
