Synthetic Studies of Neoclerodane Diterpenes from Salvia divinorum: Design, Synthesis, and Evaluation of Analogues with Improved Potency and G-protein Activation Bias at the μ Opioid Receptor
ACS Chemical Neuroscience May 8, 2020 Rachel S Crowley, Andrew P Riley, Amy F Alder et al.
Previous structure-activity relationship (SAR) studies identified the first centrally-acting, non-nitrogenous μ opioid receptor (MOR) agonist, kurkinorin (1), derived from salvinorin A. In an effort to further probe the physiological effects induced upon activation of MORs with this non-morphine scaffold, a variety of analogues were synthesized and evaluated in vitro for their ability to...
