[Problems] A compound which is useful as an active ingredient of a pharmaceutical composition for treating neuropathic pain is provided.
[Means for Solution] 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-(pyridin-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.
[问题]本发明提供了一种可作为治疗神经病理性疼痛的药物组合物的活性成分的化合物。
[解决方法]本发明人对具有 FAAH 抑制活性的化合物进行了广泛的研究,结果发现由 N-(
吡啶-3-基)氧羰基-
哌啶-4-基和苯基取代的唑类化合物或其药学上可接受的盐具有优异的 FAAH 抑制活性,从而完成了本发明。
经证实,本发明的化合物在神经病理性疼痛大鼠模型中具有优异的 FAAH 抑制活性和抗神经痛作用,因此可用作预防和/或治疗神经病理性疼痛的药物。
