The synthesis of new fentanyl analogues in which the benzene ring of the propioanilido group has been replaced by phenylpyrazole is described. Antinociceptive activity was evaluated using the writhing and hot plate tests in mice. Two compounds, and, showed interesting analgesic properties, being more potent than morphine and less than fentanyl but with longer duration of action. These compounds inhibited
描述了新的芬太尼类似物的合成,其中丙腈基的苯环已被苯基吡唑代替。使用扭体试验和热板试验在小鼠中评估抗伤害感受活性。两种化合物显示出令人感兴趣的镇痛特性,比吗啡强,比芬太尼强,但作用时间更长。这些化合物抑制了豚鼠回肠和小鼠输精管的电诱发的肌肉收缩,但没有抑制兔输精管的电诱发的肌肉收缩,并且可以被拮抗剂(纳洛酮和/或CTOP)逆转,因此表明这些化合物起到了mu激动剂的作用。最后,结合数据证实了该化合物对mu受体具有高亲和力和选择性。
