A series of 4-amino-5-vinyl-3(2H)-pyridazinones and analogues were synthesized and their antinociceptive effect was evaluated in the mouse abdominal constriction model. Several of the novel compounds showed ED(50) values in the range 6-20mg/kg/sc and demonstrated to be able to completely protect all the treated animals from the effect of the noxious stimulus at 30 mg/kg/sc. SAR studies confirmed the
合成了一系列的4-氨基-5-乙烯基-3(2H)-哒嗪酮及其类似物,并在小鼠腹部收缩模型中评估了它们的抗伤害作用。几种新化合物的ED(50)值在6-20mg / kg / sc范围内,并证明能够完全保护所有处理过的动物免受30 mg / kg / sc的有害刺激的影响。SAR研究证实,二嗪系统第4位的氨基或取代的氨基官能团和第5位的乙烯基具有重要的作用。
