Neuropeptide Y is one of the most potent appetite stimulating hormones known. Novel thiophene and benzo[b]thiophene hydrazide derivatives were synthetized and evaluated biologically as NPY Y(1) and Y(5) receptor subtype antagonists. They were found to have nanomolar binding affinities for human NPY Y(5) receptor, obtaining the lead compound, trans-N-4-[N'-(thiophene-2-carbonyl)hydrazinocarbonyl]cy
