ABSTRACT:
A medicament comprising as an active ingredient a compound or a physiologically acceptable salt thereof represented by general formula (I):wherein R1represents a dicarba-closo-dodecaboran-yl which may be substituted with a lower alkyl group, a lower alkenyl group, carboxyl group or the like; R2represents carboxyl group, a lower alkoxycarbonyl group, or hydroxyl group; and X represents a single bond or a linking group such as —CO—Y1— wherein Y1represents oxygen or —N(R3)— wherein R3represents hydrogen or a lower alkyl.
