ubstituted amino)-3(2H)-pyridazinones were prepared. Among the compounds prepared, 4-ethoxy-2-methyl-5-morpholino-3(2H)-pyridazinone (8) was evaluated to be the most attractive compound as an analgesic-antiinflammatory agent. Compound 8 was shown to be more potent in analgesic and antiinflammatory activities and less potent in toxicity than aminopyrine and phenylbutazone. Some pyridazinone derivatives
为了检查镇痛和抗炎活性,制备了各种2-烷基-或2-烯基-4-烷氧基-5-(取代的氨基)-3(2H)-哒嗪酮。在制备的化合物中,4-乙氧基-2-甲基-5-吗啉代-3(2H)-哒嗪酮(8)被认为是最有吸引力的镇痛抗炎剂。与氨基比林和苯基丁a相比,化合物8显示出更强的镇痛和抗炎活性,而毒性更低。制备了一些哒嗪酮衍生物,其中可能的8个活性位点被消除和改变,并通过类似的试验评估了它们的活性。根据现有数据,还讨论了一系列4-烷氧基-2-取代的-5-(取代的氨基)-3(2H)-哒嗪酮的结构-活性关系。
