1、ChineseJournalofNewDrugs2011,20(2)实验研究非甾体抗炎药ML4000的合成及生物活性研究12221郑志超,梅林雨,高晶,罗振福,孙有光(1天津理工大学化学化工学院,天津300191;2天津药物研究院,天津300193)[摘要]目的:合成非甾体抗炎药ML4000并研究其生物活性。方法:ML4000以环氧合酶(COX)和5脂氧合酶(5LOX)双重抑制剂利克飞龙(licofelone,ML3000)为先导化合物,结构上链接了1个一氧化氮(NO)供体;通过灌胃给药,观察ML4000在动物体内
2、的初步代谢、抗炎活性、胃肠道作用以及血清和胃黏膜113NO水平。结果:ML4000经IR,MS,HNMR,CNMR以及元素分析等确证结构;大鼠灌胃ML4000(10mg-1kg)0.25h后,即可测到ML4000代谢为ML3000;ML4000抗炎活性与ML3000相当;连续14d灌胃(60-1-1mgkg,qd),未见大鼠胃肠道出血;灌胃给药(60mgkg)1h后大鼠血清和胃黏膜NO量显著增加。结论:合成的ML4000具有较强的抗炎作用,胃肠道耐受性好,并能够释放出NO。[关键词]非甾体抗炎药;一氧化氮供体;利克飞龙;合
