In this work, a series of arylpiperazine derivatives were synthesized and screened by in vivo pharmacological trials. Among the tested compounds, 2-(4-(3-(trifluoromethyl)phenyl)piperazin-1-yl)-1-phenylethanone (18) and 2-(4-(2,3-dimethylphenyl)piperazin-1-yl)-1-phenylethanone (19) exhibited potent analgesic activities in both the mice writhing and mice hot plate tests. They showed more than 70% inhibition relative to controls in the writhing test, and increased latency by 116.0% and 134.4%, respectively, in the hot plate test. Furthermore, compound 18 was also active in the models of formalin pain and neuropathic pain without sedative side effects.
在这项工作中,一系列苯基哌嗪衍生物被合成并通过体内药理学试验进行筛选。在测试的化合物中,2-(4-(3-(三氟甲基)苯基)哌嗪-1-基)-1-苯乙酮(18)和2-(4-(2,3-二甲基苯基)哌嗪-1-基)-1-苯乙酮(19)在小鼠扭体和大鼠热板实验中表现出强大的镇痛活性。在扭体实验中,它们相对于对照组显示出超过70%的抑制率,且在热板测试中分别将延迟时间增加了116.0%和134.4%。此外,化合物18在没有镇静副作用的情况下,在福尔马林痛和神经病理性痛模型中也表现出活性。
