OXYGENIC HETEROCYCLIC DERIVATIVES

摘要

Oxygenic heterocyclic derivatives of general formula (I), salts thereof, and solvates or hydrates of those [wherein R<1> is formula (II) (wherein R<4> is C11-C20 alkyl or the like) or the like; R<2> is C1-C10 alkyl or the like; R<3> is H or formula (III) (wherein R<5> is C1-C10 alkyl); and A is C1-C3 alkylene or the like]. These compounds exhibit a potent inhibitory activity against cysteine proteases such as calpain.
