A series of N2-2-[4-aryl(benzyl)-1-piperazinyl(piperidinyl)]ethyl}pyrrolo[3,4-d]pyridazinones 4 and related derivatives 5 were synthesized as potential analgesic agents. The structures of the new compounds were elucidated by micro, spectral and X-ray analysis. Analgesic activity of the compounds was investigated in the phenylbenzoquinone induced ‘writhing’ and ‘hot plate’ test in mice and at radioligand
合成了一系列N2- 2- [4-芳基(苄基)-1-哌嗪基(哌啶基)]乙基}吡咯并[3,4- d ]吡啶并壬酮4和相关衍生物5作为潜在的止痛剂。通过微观,光谱和X射线分析阐明了新化合物的结构。在小鼠和放射性配体结合试验中,通过苯苯醌诱导的“扭体”和“热板”试验研究了化合物的镇痛活性。在“扭体”试验中,所有化合物无一例外地比乙酰水杨酸(ASA)具有更高的活性,ED 50值为0.04至11 mg / kg(ip)(ASA为ED 50 – 39.15 mg / kg)。三种化合物4c在“热板”试验中观察到了镇痛作用,e,f的剂量是吗啡剂量的3-5倍(ED 50 -3.39 mg / kg)。在4c,e,f的放射性配体结合试验中,只有化合物4f对μ阿片受体的亲和力与曲马多相似。所述pyrrolopyridazinones的急性毒性4,5也进行了研究,并在2000毫克/千克(观察到非毒性作用5A 1
