New N‐(dimethylamino)ethyl derivatives of phthalazinones and pyridopyridazinones 7, 9 were synthesized and assayed as potential analgesic agents in the hot‐plate, tail‐flick, and writhing tests. Pharmacological assay demonstrated that eight (in ten) of the newly synthesized compounds showed antinociceptive activity. Especially, 2‐[2‐(dimethylamino)ethyl]‐4‐phenyl‐2H‐phthalazin‐1‐one 7a showed remarkably
合成了酞嗪酮和吡啶并哒嗪酮 7、9 的新型 N-(二甲氨基)乙基衍生物,并在热板、甩尾和扭体试验中作为潜在的镇痛剂进行了分析。药理学分析表明,新合成的化合物中有八种(十分之八)显示出镇痛活性。特别是,2-[2-(二甲氨基)乙基]-4-苯基-2H-酞嗪-1-one 7a在所有测试中都显示出显着更高的镇痛活性。这与对脊柱上、脊柱和外周结构的影响有关。热板对疼痛刺激的敏感性下降高于安乃近。
