A compound which is useful as an active ingredient of a pharmaceutical composition for treating neuropathic pain is provided. The present inventors have made extensive studies on compounds having an FAAH inhibitory activity, and as a result, have found that an azole compound substituted with an N-(pyridine-3-yl)oxycarbonyl-piperidin-4-yl group and a phenyl group or a pharmaceutically acceptable salt thereof has an excellent FAAH inhibitory activity, thereby completing the present invention. The compound of the present invention is confirmed to have an excellent FAAH inhibitory activity and an antiallodynic effect in rat models with neuropathic pain, and thus is useful as an agent for preventing and/or an agent for treating neuropathic pain.
提供了一种化合物,该化合物可作为制备用于治疗神经病性疼痛的药物组合物的活性成分。本发明人对具有FAAH抑制活性的化合物进行了广泛的研究,并发现一种咪唑化合物,其取代有N-(吡啶-3-基)氧羰基哌啶-4-基团和苯基,或其药学上可接受的盐具有出色的FAAH抑制活性,从而完成了本发明。本发明的化合物已被证实在神经病性疼痛的大鼠模型中具有出色的FAAH抑制活性和抗痛觉过敏作用,因此可用作预防和/或治疗神经病性疼痛的药剂。
