ABSTRACT:
The present invention provides a compound represented by the formula (I)wherein R1is a hydrogen atom, a halogen atom, an optionally substituted hydrocarbon group, an optionally substituted heterocyclic group, an optionally substituted hydroxy group, an optionally substituted thiol group or an optionally substituted amino group,A is an optionally substituted cyclic amino group or —NR2—W—D wherein R2is a hydrogen atom or an alkyl group, W is a bond or a divalent acyclic hydrocarbon group, and D is an optionally substituted cyclic group, an optionally substituted amino group or an optionally substituted acyl group,B is an optionally substituted hydrocarbon group or an optionally substituted heterocyclic group,X is an oxygen atom, a sulfur atom or an optionally substituted nitrogen atom, andY is a bond or a divalent acyclic hydrocarbon group, or a salt thereof, which is useful for the prophylaxis or treatment of diabetic neuropathy and the like.
