kappa-opioid receptor ligands have raised interest for their apparent effects on mood. The potent and selective kappa-agonist salvinorin A has short-lasting (15 min) depressive-like effects in rats in behavioral models used to study mood disorders. Two series of salvinorin derivatives modified at C(2) and C(18), respectively, were synthesized and their kappa-opioid receptor affinities, potencies, and efficacies were evaluated using in vitro receptor binding and biochemical functional assays. Modification at C(2) yielded potent kappa-agonists that are predicted to have improved metabolic stability (14a, 15a) or increased water solubility (10b). Our preliminary SAR study at C(18) suggested that this part of the molecule interacts with a tight lipophilic pocket of the K-receptor. (c) 2006 Elsevier Ltd. All rights reserved.

Salvinorin A is a psychoactive natural product that has been found to be a potent and selective kappa opioid receptor agonist in vitro and in vivo. The activity of salvinorin A is unusual compared to other opioids such as morphine in that it mediates potent kappa opioid receptor signaling yet leads to less receptor downregulation than observed with other kappa agonists. Our initial chemical modifications of salvinorin A have yielded one analogue, herkinorin (1c), with high affinity at the mu OR. We recently reported that 1c does not promote the recruitment of beta-arrestin-2 to the mu OR or receptor internalization. Here we describe three new derivatives of 1c (3c, 3f, and 3i) with similar properties and one, benzamide 7b, that promotes recruitment of beta-arrestin-2 to the mu OR and receptor internalization. When the important role mu opioid receptor regulation plays in determining physiological responsiveness to opioid narcotics is considered,mu opioids derived from salvinorin A may offer a unique template for the development of functionally selective mu opioid receptor-ligands with the ability to produce analgesia while limiting adverse side effects.
