To provide a novel and excellent agent for treating or preventing nociceptive pain, neuropathic pain, cancer pain, headache, bladder function disorder and the like, based on the inhibitory action on the capsaicin receptor VR1 activation.
The present invention was accomplished by confirming that a benzamide derivative characterized by the possession of a benzene ring in which a single ring is condensed on the nitrogen atom of amido group and possession of a lower alkylamino or an amino group substituted with a ring group at the neighboring position of said amido group has a strong inhibitory action on VR1 activation and excellent pharmacological actions based on this and by finding that it can become an excellent agent for treating or preventing VR1-involved diseases such as nociceptive pain, neuropathic pain, cancer pain, headache, bladder function disorder and the like.
本发明提供了一种基于对辣椒素受体VR1激活的抑制作用的新型优良药剂,用于治疗或预防伤害性疼痛、神经病理性疼痛、癌症疼痛、头痛、膀胱功能障碍等疾病。本发明通过确认一种苯甲酰胺衍生物,其特征在于其苯环上的单环在酰胺基氮原子上被紧缩,其低烷基氨基或邻位于酰胺基的环基取代的氨基具有对VR1激活的强抑制作用和优良的药理作用,从而发现它可以成为治疗或预防伤害性疼痛、神经病理性疼痛、癌症疼痛、头痛、膀胱功能障碍等VR1相关疾病的优良药剂。
