A systematic review on the kappa opioid receptor and its ligands: New directions for the treatment of pain, anxiety, depression, and drug abuse
2022, European Journal of Medicinal ChemistryCitation Excerpt :As mentioned above, salvinorin A is an interesting non-opiate KOR agonist that has been used as an important prototype for the development of related drug candidates targeting different opioid receptors. In 2007, Prisinzano and coworkers synthesized many salvinorin compounds with modifications at the C1 ketone to explore the effects at this position [79]. They discovered six compounds that showed antagonistic activity on opioid receptors, five of which were antagonists at KOR, MOR, and DOR, and one of which was an antagonist at MOR and DOR, but a partial agonist at KOR.
A review of salvinorin analogs and their kappa-opioid receptor activity
2018, Bioorganic and Medicinal Chemistry LettersCitation Excerpt :Removal of the C1 ketone in the A ring (52) causes a modest loss (3–6.2-fold) in potency and affinity (4.5-fold), whereas introduction of an H-bond donor as in alcohol 53 results in a steeper loss in affinity (280-fold).38,66 In fact, alcohol 53 was reported in one publication as an antagonist of κ-OR.66 Protecting this alcohol did recover some activity, as in mesylate 54 (60-fold less active than SalA).66
Pharmacology and Structure-Activity Relationship of Natural Products With Psychoactive Effects From Salvia divinorum, Mitragyna speciosa, and Ayahuasca
2017, Studies in Natural Products ChemistryCitation Excerpt :Another investigation into structural derivatives of SA investigated changes to the ketone functional group in position 1 [112,113]. Interestingly, reduction of the ketone group to a hydroxyl group, substitution with sulfur, or replacement with a double bond led to antagonistic activity at all opioid receptors, although the affinity was significantly reduced with the removal of the electron-rich environment in position 1 [113]. The current structure-activity relationship investigations for SA indicate that the pharmacophore is restrictive and does not allow for significant modifications to increase binding affinity or activity.
