BMS-986122 is a selective, potent positive allosteric modulator of the mu-opioid receptor (μ-OR). BMS-986122 shows potentiation of orthosteric agonist-mediated β-arrestin recruitment, adenylyl cyclase inhibition, and G protein activation. BMS-986122 potentiates DAMGO-mediated [35S]GTPγS binding in mouse brain membranes[1][2].

BMS-986122 may exhibit an antinociception effect in vivo by increasing the efficiency of Met-enkephalin (met-Enk) to inhibit γ aminobutyric acid (GABA) release in the periaqueductal gray region of the brain.
