Structure-based parallel medicinal chemistry approach to improve metabolic stability of benzopyran COX-2 inhibitors.

ABSTRACT

Combination of the structure-based design and solid-phase parallel synthesis provided an integrated approach to rapidly develop the structure-activity relationship of benzopyran COX-2 inhibitors. Binding free energies predicted by free energy perturbation theory yielded good agreement with experimental results. New potent and selective lead compounds with improved metabolic properties were identified.
