Miniaturised methods have been used to construct dose-response curves for the effects of inhibitory drugs on prostaglandin synthesis using individual rectal biopsies obtained from patients with ulcerative colitis. The potency of different drugs has been compared. Sulphasalazine, 5 amino salicylic acid (5-ASA) and N-acetyl 5-ASA inhibited prostaglandin synthesis at high concentration, but sulphapyridine and prednisolone did not. Indomethacin and flurbiprofen were considerably more potent inhibitors. These data imply that sulphasalazine does not act by simple inhibition of prostaglandin synthesis but leave open the possibility that sulphasalazine or 5-ASA may be inhibitors of the synthesis of related lipoxygenase products.
已采用小型化方法,利用从溃疡性结肠炎患者获取的单个直肠活检组织,构建了抑制性药物对前列腺素合成影响的剂量反应曲线。比较了不同药物的效力。柳氮磺胺吡啶、5-氨基水杨酸(5-ASA)和N-乙酰5-ASA在高浓度时抑制前列腺素合成,但磺胺吡啶和泼尼松龙则无此作用。吲哚美辛和氟比洛芬是效力更强的抑制剂。这些数据表明,柳氮磺胺吡啶并非通过简单抑制前列腺素合成起作用,但柳氮磺胺吡啶或5-ASA有可能是相关脂氧合酶产物合成的抑制剂。
