Sulphasalazine is a potent and selective inhibitor in vitro of prostaglandin 15-hydroxydehydrogenase in rabbit colon (ID50 = 50 micrometer) and in several other organs of different species, but does not inhibit prostaglandin delta-13 reductase or microsomal prostaglandin synthesis from arachidonic acid. It is suggested that this action may underly the therapeutic usefulness of sulphasalazine in ulcerative colitis for the prevention of relapse.
柳氮磺胺吡啶在体外是兔结肠中前列腺素15 - 羟基脱氢酶的强效选择性抑制剂(半数抑制浓度=50微摩尔),在其他几种不同物种的器官中也是如此,但它不抑制前列腺素δ-13还原酶或花生四烯酸的微粒体前列腺素合成。有人认为,这一作用可能是柳氮磺胺吡啶在溃疡性结肠炎预防复发方面具有治疗作用的基础。
