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(5-LOX)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在动物体内的初步代谢、抗炎活性、胃肠道作用以及血清和胃黏膜NO水平。结果:ML4000经IR,MS,1H NMR,13C NMR以及元素分析等确证结构;大鼠灌胃ML4000(10 mg.kg-1)0.25 h后,即可测到ML4000代谢为ML3000;ML4000抗炎活性与ML3000相当;连续14 d灌胃(60mg.kg-1,qd),未见大鼠胃肠道出血;灌胃给药(60 mg.kg-1)1 h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。Objective: To synthesize the non-steroidal anti-inflammatory drug(NSAID) ML4000 and evaluate its biological activity.Methods: Licofelone,a balanced inhibitor of cyclooxygenase(COX) and 5-lipoxygenase(5-LOX),covalently bound to one NO-donating moiety to produce ML4000.The metabolism of ML4000 in vivo,the anti-inflammatory activity,and the effects on gastrointestinal tract(GI),and NO level in the serum and gastric mucosa were determineed.Results: ML4000 structure was confirmed by IR,MS,1H NMR,13C NMR and elemental analysis.In rats,the metabolite ML3000 was detected 0.25h after oral administration of 10mg·kg-1 ML4000.ML4000 was equipotent to ML3000 in anti-inflammatory activity.No gastrointestinal bleeding and ulcers were found in rats after treatment with 60mg·kg-1,qd ML4000 for consecutive 14 days.Significant increase of NO in the serum and gastric mucosa was found 1 h after oral ML4000 60mg·kg-1.Conclusion: The synthesized ML4000 has satisfactory anti-inflammatory activity,gastrointestinal tolerability and significant NO releasing activity.
