A novel series of trans-8-aminomethyl-1-oxa-3-azaspiro[4.5] decan-2-one derivatives was identified with potent NPY Y5 antagonist activity. Optimization of the original lead furnished compounds 23p and 23u, which combine sub-nanomolar Y5 activity with metabolic stability, oral bioavailability, brain penetration and strong preclinical profile for development. Both compounds significantly inhibited the food intake induced by a Y5 selective agonist with minimal effective doses of 3 mg/kg po. (C) 2010 Elsevier Ltd. All rights reserved.
