title: Use of the chemical structure of peptides as the starting point to design nonpeptide agonists and antagonists at peptide receptors: examples with cholecystokinin and tachykinins.
abstract: This review summarizes a design strategy to give examples of nonpeptides starting from cholecystokinin (CCK-A and -B) and tachykinins (substance P) (NK-1, -2, -3) as potent functional agonists and antagonists with utility as therapeutic agents.
