6iM, and 6jM showed significant analgesic activity and compounds 6cM and 6iM showed highly significant activity against the standard drug Diclofenac sodium using acetic acid-induced writhing model. Among all the synthesized compounds which show potent analgesic activity such as 6aP, 6aM, 6cM, 6iM, and 6jM were further evaluated for acute- ulcerogenic activity. Among all compound 6cM and 6iM was found
一系列新的6-溴-3-(2-吗啉代甲基氨基)-6-取代的苯基嘧啶-4-基-2H-色酮-2-酮(6aM – 6jM)和3-(2-((哌啶-由3-(2-氨基-6-嘧啶-4)合成了1-yl)甲基氨基)-6-取代的苯基嘧啶-4-基)-6-溴-2H-色酮-2-酮(6aP – 6jP) -yl)-6-bromo-2H-chromen-2-one(5a – 5j)由3-乙酰基-6-bromo-2H-chromen-2-one(3)。反应通过常规方法和微波方法进行。与常规方法相比,微波法的显着特点是反应速度快,反应条件更干净,化学收率提高,通过IR,1 H NMR,13 C NMR,质谱技术对合成的化合物进行了表征。通过体内止痛活性,以20mg / kg体重的剂量筛选所有化合物。在所有合成的化合物中,化合物6aP,6aM,6cM,6iM和6jM显示出明显的镇痛活性,化合物6cM和6iM使用乙酸诱导的扭体模
