The present invention provides an agent for preventing or treating neuropathy having superior action and low toxicity. This agent comprises a compound represented by the formula: wherein ring A is a 5-membered aromatic heterocycle containing 2 or more nitrogen atoms, which may further have substituent(s); B is an optionally substituted hydrocarbon group or an optionally substituted heterocyclic group; X is a divalent acyclic hydrocarbon group; Z is —O—, —S—, —NR
