and compared with acetyl salicylic acid. The compound with the maximal combination of safety and analgesic efficacy was 4-¿3-[4-(4-fluorophenyl-1-piperazinyl)propyl]¿-2H-pyrido[3,2-b]-1, 4-oxazin-3(4H)-one (6c) with ED50 values of 12.5 mg/kg po (mouse: phenylquinone writhing test) and 27.8 mg/kg po (rat: acetic acid writhing test), respectively. Compound 6c proved to be more active than aspirin with
合成了一系列新的N-取代的吡啶并[3,2-b]恶嗪酮,进行了药理学评估,并与乙酰水杨酸进行了比较。具有最大安全性和止痛效果的化合物为4-?? 3- [4-(4-氟苯基-1-哌嗪基)丙基] ??-2H-吡啶基[3,2-b] -1,4-恶嗪- 3(4H)-一(6c),ED50值分别为12.5 mg / kg po(小鼠:苯醌扭曲试验)和27.8 mg / kg po(大鼠:乙酸扭曲试验)。事实证明,化合物6c比阿司匹林更具活性,安全指数为5.1。
