A series of trans-3-oxospiro[(aza)isobenzofuran-1(3H),1′-cyclohexane]-4′-carboxamide derivatives were synthesized to identify potent NPY Y5 receptor antagonists. Of the compounds, 21j showed high Y5 binding affinity, metabolic stability and brain and cerebrospinal fluid (CSF) penetration, and low susceptibility to P-glycoprotein transporters. Oral administration of 21j significantly inhibited the Y5 agonist-induced food intake in rats with a minimum effective dose of 1 mg/kg. This compound was selected for proof-of-concept studies in human clinical trials.

The synthesis of neuropeptide Y antagonist 1, currently under clinical investigation for the treatment of obesity, is described. The convergent synthesis from trans-spirolactone carboxylic acid intermediate 2a and aminopyrazole 3 is predicated on a stereo
