Abstract
Salvinorin A is the most potent naturally occurring opioid agonist with a high selectivity and affinity for kappa-opioid receptor. To explore its structure-activity relationships, modifications at the C(4) position have been studied and a series of salvinorin A derivatives were prepared. These C(4)-modified salvinorin A analogues were screened for binding and functional activities at the human kappa-opioid receptor and several potent new agonists have been identified.
