The present invention relates to a novel 3-aminobenzamide compound represented by the following formula which effectively inhibits vanilloid receptor subtype 1 (VR1) activity (wherein, for example, R1 is a C1-6 alkyl group which may be substituted, R2 is a hydrogen atom, a C1-6 alkyl group or a C1-6 alkoxy group which may be substituted, R3 is a hydrogen atom or a C1-6 alkyl group, R4 is a C1-6 alkyl group, a C1-6 alkoxy group, or a halo C1-6 alkyl group, m is an integer of 1 to 5 and P is a carbon or hetero ring) or a pharmaceutically acceptable salt thereof. The pharmaceutical composition comprising as active ingredients the 3-aminobenzamide compound or a pharmaceutically acceptable salt thereof is useful for treating diseases involved in VR1 activity such aspain, acutepain, chronicpain, neuropathic pain, rheumatoid arthritis pain, and neuralgia.
本发明涉及一种由下式表示的新型3-氨基苯甲酰胺化合物,它能有效地抑制类香草素受体亚型1(VR1)的活性(其中,例如,R1是可被取代的C1-6烷基,R2是氢原子、R3 是氢原子或 C1-6 烷基,R4 是 C1-6 烷基、C1-6 烷氧基或卤代 C1-6 烷基,m 是 1 至 5 的整数,P 是碳环或杂环)或其药学上可接受的盐。包含作为活性成分的 3-氨基苯甲酰胺化合物或其药学上可接受的盐的药物组合物可用于治疗涉及 VR1 活性的疾病,如阿斯匹灵、急性阿斯匹灵、慢性阿斯匹灵、神经性疼痛、风湿性关节炎疼痛和神经痛。
