sb612111

NOP receptor antagonist

SB-612111 is a novel and potent human opiate receptor-like orphan receptor (ORL-1) antagonist with a high affinity for hORL-1 (Ki=0.33 nM). SB-612111 exhibits selectivity for μ-, κ- and δ-receptors with Ki values of 57.6 nM, 160.5 nM and 2109 nM, respecticely. SB-612111 effectively antagonizes the pronociceptive action of Nociceptin in an acute pain model[1]. [1]. Paola F Zaratin, et al.

SB-612111 hydrochloride is a potent, novel orphan receptor for opioid receptors (ORL-1) antagonist with high affinity for hORL-1 and a Ki value of 0.33 nM. SB-612111 hydrochloride is able to act on mu-receptor (Ki: 57.6 nM), κ SB-612111 hydrochloride effectively antagonized the nociceptive effects of Nociceptin in an acute pain model.
