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-, -NR2-, -CONR2- or -NR2CO- (R2 is a hydrogen atom or an optionally substituted alkyl group);Y is a bond or a divalent acyclic hydrocarbon group;R1 is an optionally substituted cyclic group, an optionally substituted amino group or an optionally substituted acyl group, provided that when the 5-membered aromatic heterocycle represented by ring A is imidazole, then Z should not be -O-, or a salt thereof.

In search for a new antibacterial agent with improved antimicrobial spectrum and potency, we designed and synthesized a series of novel 3‐((Z)‐2‐(5‐methyl‐1,2,4‐oxadiazol‐3‐yl)‐2‐(4‐nitrophenyl)vinyl)‐4H‐chromen‐4‐ones 7a, 7b, 7c, 7d, 7e, 7f, 7g, 7h by convergent synthesis approach. All the synthesized compounds were assayed for their in vitroantibacterial activities against gram‐negative and gram‐positive
