ABSTRACT:
The present invention provides a compound represented by the formula (I):(whereinR1is a lower alkyl substituted by a lower alkoxy or a heterocyclic group, or a heterocyclic group;R2is a lower alkyl optionally substituted by a phenyl; andR3is a lower alkyl optionally substituted by a halogen, a lower alkoxy or a phenyl, or a fused polycyclic hydrocarbon group), which is well absorbed orally, exhibits durability of good blood level and has potent calpain inhibitory activity.
