4-oxadiazole derivatives were synthesized and evaluated for anti-allodynic activity. Structure-activity relationship studies identified 1-4-[3-(2,4-dichlorophenyl)-1,2,4-oxadiazol-5-yl]butyl}piperidine (39) with excellent affinity for the σ1 receptor and selectivity for the σ2 receptor, with poor activity to other central nervous system neurotransmitter receptors and transporters associated with pain.

在这项研究中,合成了一系列苯基-1,2,4-四恶二唑衍生物,并评估了其抗痛觉过敏活性。构效关系研究确定了1- 4- [3-(2,4-二氯苯基)-1,2,4-恶二唑-5-基]丁基}哌啶(39)对σ1受体具有出色的亲和力,对σ2受体,对其他中枢神经系统神经递质受体和与疼痛相关的转运蛋白的活性较弱。化合物39显示出在慢性收缩性损伤诱导的神经性大鼠中抑制福尔马林诱导的退缩和减轻机械性异常性疼痛的剂量依赖性功效。这些结果表明化合物39发挥有效的抗痛觉过敏活性,可以被认为是治疗神经性疼痛的有前途的候选药物。
