A 3,4-dihydrobenzoxazine compound of the present invention is represented by the following formula [1] (wherein X is a nitrogen atom or CR3; R1 is a hydrogen atom or a halogen atom; R2 is a C1-6 alkoxy group which may be substituted with the same or different 1 to 5 substituents selected from a halogen atom and a hydroxyl group; and R3 is a halogen atom. However, R1 is a halogen atom when X is CR3). This compound is effective in treating diseases to which the vanilloid receptor subtype 1 (VR1) activity is involved, such as pain, etc.
本发明的 3,4-二氢苯并恶嗪化合物由下式[1]表示(其中 X 是氮原子或 CR3;R1 是氢原子或卤素原子;R2 是 C1-6 烷氧基,可被选自卤素原子和羟基的相同或不同的 1 至 5 个取代基取代;R3 是卤素原子)。然而,当 X 为 CR3 时,R1 为卤原子。)该化合物可有效治疗涉及类香草素受体亚型 1(VR1)活性的疾病,如疼痛等。
