Description: PF-5190457 is an orally available, potent and selective ghrelin receptor inverse agonist. PF-5190457 potently increases insulin secretion in glucose-stimulated human islets. PF-5190457 has a superior balance of ghrelin receptor pharmacology and off-target selectivity. On the basis of its promising pharmacological and safety profile, PF-5190457 was advanced to human clinical trials.
