Key points The authors report that modifying the C(4) position of salvinorin A yields analogues that bind to and activate the human kappa opioid receptor, and that several of these analogues are full agonists. This indicates that the C(4) position can be altered while retaining or achieving full receptor activation.

Abstract

Salvinorin A, a compound isolated from the plant Salvia divinorum, is a potent and highly selective agonist for the kappa opioid receptor. For exploration of its structure and activity relationships, further modifications, such as reduction 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 new full agonists have been identified.
