Abstract

A series of substituted 4-alkoxy-2-aminopyridines 2, which were formally derived from neuropeptide Y1 antagonist 1 by replacing the morpholino portion with alkoxy groups, were synthesized and evaluated as neuropeptide Y Y1 receptor antagonists. Primary structure-activity relationships and identification of potent 4-alkoxy derivatives are described.
