Synthesis and evaluation of 5,5-diphenylimidazolones as potent human neuropeptide Y5 receptor antagonists

A series of novel 5,5-diphenylimidazolones was synthesized and evaluated for activity against the human neuropeptide Y5 receptor. The 3-pyridyl analog 46 demonstrated an IC50 of 8.3 nM with a favorable pharmacokinetic profile in rats, but was ineffective in reducing food intake.
