This study describes the integrated application of parallel synthesis and computational chemistry to the design of potent nonpeptide antagonists for the neuropeptide Y-1 (NPY1) receptor. A lead molecule was modeled in the active site of the NPY1 receptor, and a potentially fruitful region for analog construction was identified. Synthesis of suitable scaffolds followed by solution phase generation of a small library of analogs produced a compound with 5-fold improvement in binding over the already potent lead. This new compound was shown to be an unanticipated side product of the parallel synthesis reaction.
