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.
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.

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.
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.
Based on a large scale analysis of known opioid receptor ligands a template was created through manual overlaying and alignment which has identified several mu-specific areas within the receptor. In this analysis, it is noted, etonitazene now more closely matches another, separate mu-specific region, sharing only a small area in common with the ...
μ-opioid receptor (MORs) are inhibitory receptors that can cause a decrease in pain if activated and are expressed in the VB especially in the VPL. [4] When MORs are activated, by an agonist like DAMGO for example, pain-related behaviors are decreased for a certain amount of time.
While over 100 variants have been identified for the opioid mu-receptor, the most studied mu-receptor variant is the non-synonymous 118A>G variant, which results in functional changes to the receptor, including lower binding site availability, reduced mRNA levels, altered signal transduction, and increased affinity for beta-endorphin.
