It is found out that compounds represented by general formula (I) bind selectively to cannabinoid 2 receptor (CB2R) and thus exhibit CB2R antagonism or CB2R agonis wherein R1 represents optionally substituted alkylene; R2 represents hydrogen, alkyl, a group represented by the formula —C(═R5)—R6 (wherein R5 represents O or S; and R6 represents alkyl, alkoxy, alkylthio, etc.) or a group represented by the formula SO2R7 (wherein R7 represents allyl, etc.); m is an integer of from 0 to 2; and A represents optionally substituted aryl, etc.
发现由通式(I)表示的化合物选择性地结合到
大麻素2受体(CB2R),因此表现出CB2R拮抗或CB2R激动作用,其中R1代表可选取代的烷基;R2代表氢,烷基,由公式—C(═R5)—R6表示的基团(其中R5表示O或S;R6表示烷基,烷氧基,烷
硫基等),或由公式SO2R7表示的基团(其中R7表示烯丙基等);m为0到2的整数;A代表可选取代的芳基等。
