They are also referred to as μ(mu)-opioid peptide (MOP) receptors. The prototypical μ-opioid receptor agonist is morphine, the primary psychoactive alkaloid in opium and for which the receptor was named, with mu being the first letter of Morpheus, the compound's namesake in the original Greek.
Although opioid receptor families share many similarities, their structural differences lead to functional difference. Thus, mu-opioid receptors induce relaxation, trust, satisfaction, and analgesia. [18] [19] This system may also help mediate stable, emotionally committed relationships.
Even though μ-opioid receptor (MOR) targeting drugs have been used for a long time, not much is known about the structure-activity relationship and the ligand-receptor interactions on the basis of well-defined biological effects on receptor activation or inhibition. Also, the distinction in the receptor-ligand interaction patterns of agonists ...
BMS‐986122 is a selective positive allosteric modulator (PAM) of the μ-opioid receptor (MOR). [1] [2] [3]MOR PAMs like BMS-986122 could be useful as novel analgesics with reduced side effects compared to conventional opioid analgesics.

The receptors for enkephalin are the delta opioid receptors and mu opioid receptors. Opioid receptors are a group of G-protein-coupled receptors, with other opioids as ligands as well. The other endogenous opioids are dynorphins (that bind to kappa receptors), endorphins (mu receptors), endomorphins, and nociceptin-orphanin FQ.
Methylnaltrexone is a peripheral acting mu-opioid receptor antagonist, and does not cross the blood brain barrier. [9] Methylnaltrexone has restricted access through the blood brain barrier because it is a quaternary amine, which carries a positive charge when in a solution.
Ohmefentanyl (also known as β-hydroxy-3-methylfentanyl, OMF and RTI-4614-4) [1] is an extremely potent opioid analgesic drug which selectively binds to the μ-opioid receptor. [2] [3] There are eight possible stereoisomers of ohmefentanyl.
