Abstract

A homology model of the nicotinic acid receptor GPR109A was constructed based on the X-ray crystal structure of bovine rhodopsin. An HTS hit was docked into the homology model. Characterization of the binding pocket by a grid-based surface calculation of the docking model suggested that a larger hydrophobic body plus a polar tail would improve interaction between the ligand and the receptor. The designed compounds were synthesized, and showed significantly improved binding affinity and activation of GPR109A.
