The μ-opioid receptors (MOR) are a class of opioid receptors with a high affinity for enkephalins and beta-endorphin, but a low affinity for dynorphins. They are also referred to as μ( mu )-opioid peptide (MOP) receptors.
An animated view of the human κ-opioid receptor in complex with the antagonist JDTic. Opioid receptors are a group of inhibitory G protein-coupled receptors with opioids as ligands. [1] [2] [3] The endogenous opioids are dynorphins, enkephalins, endorphins, endomorphins and nociceptin. The opioid receptors are ~40% identical to somatostatin ...
A dual DOR and κ-opioid receptor (KOR) PAM, BMS-986187, derived from BMS-986122, has been developed and is selective for these receptors over the MOR. [9] [1] [2] [6] [10] Another MOR PAM with a simpler synthesis, MS1, was subsequently developed and has shown similar effects to those of BMS-986122.

U-47700 itself is the most potent mu opioid agonist from this class, around 7-10x the potency of morphine. Some other compounds such as 3,4-MDO-U-47700 and N-Ethyl-U-47700 retain similar mu selectivity but with lower potency similar to that of morphine, or have a mixture of mu and kappa mediated effects, such as U-48800. Most utopioid ...
Opioid receptors belong to the G protein-coupled receptor family and include μ, κ, δ, and nociceptinorphanin-FQ receptors. [6] While activation of opiate receptors initiates a diverse array of responses, opiates typically serve as depressants , and are widely used and developed as analgesics .
SR-14968 is a drug which acts as a biased agonist at the μ-opioid receptor, selective for activation of the G-protein signalling pathway over β-arrestin 2 recruitment. It is closely related to other compounds such as brorphine and SR-17018.
