The object of the present invention is to provide a novel trehalose compound having a high affinity for an adenosine A3 receptor. The trehalose compound of the present invention is represented by General Formula (1):wherein X and X′ represent a hydrogen atom, and the like; Y and Y′ independently represent an oxygen atom, and the like; R1 and R2 independently represent a C1-C6 alkyl group; and R3 and R4 independently represent a C3-C6 alkyl group. The trehalose compound of the present invention has a remarkably high affinity for an adenosine A3 receptor.
