A series of 5-arylidenepyridazin-3-ones substituted in the 2-position by an arylpiperazinoalkyl moiety (2-16) was synthesized and evaluated for analgesic activity. In the phenylbenzoquinone-induced writhing test, Mannich bases 2-14 were the most active compounds (6.1 < or = ED50 < or = 43.0 mg/kg, orally; ED50 is the half-maximal effective dose). Pyridazinones 8 and 9, with a 3-chlorophenylpiperazinomethyl
合成了在2-位被芳基哌嗪子烷基部分(2-16)取代的一系列5-芳基吡啶并嗪-3-酮,并评价了其镇痛活性。在苯基苯醌诱导的扭体试验中,曼尼希碱2-14是活性最高的化合物(口服6.1 <或= ED50 <或= 43.0 mg / kg; ED50是最大有效剂量的一半)。具有3-氯苯基哌嗪子甲基取代基的吡嗪酮8和9也表现出显着的抗炎和退热作用。对苯基苯醌诱导的扭体试验中的活性进行汉斯分析,并获得与亲脂性和哈米特常数的显着相关性。
