and inheritable pain conditions. The (S)-N-chroman-3-ylcarboxamide series, exemplified by 1, was used as a starting point for development of new channel blockers, resulting in the phenethyl nicotinamide series. The structure and activityrelationship for this series was established and the metabolic issues of early analogues were addressed by appropriate substitutions. Compound 33 displayed acceptable
