orphanin fq(1 11)

Orphanin FQ(1-11) is a peptide fragment containing amino acids 1-11 of Nociceptin. Orphanin FQ(1-11) is a potent agonist of the ORL1/KOR-3 receptor (Ki = 55 nM) and displays no affinity for opioid receptors, including μ, δ, κ1 and κ3 receptors (Ki >1000 nM). Orphanin FQ(1-11) displays analgesic properties in CD-1 mice.

Orphanin FQ(1-11) TFA, a fragment of orphanin FQ or nociceptin (OFQ/N), acts as a powerful NOP receptor (ORL-1; OP4) agonist with a K i of 55 nM. It lacks affinity for μ, δ, κ1, and κ3 receptors (K i >1000 nM), demonstrating specificity, and exhibits analgesic properties in CD-1 mice [1] [2].

Orphanin FQ(1-11) acetate(178249-41-7 free base) is a peptide fragment containing amino acids 1-11 of Nociceptin. Orphanin FQ(1-11) acetate(178249-41-7 free base) is a potent agonist of the ORL1/KOR-3 receptor (Ki = 55 nM) and displays no affinity for opioid receptors, including μ, δ, κ1 and κ3 receptors (Ki >1000 nM). Orphanin FQ(1-11) acetate(178249-41-7 free base) displays analgesic properties in CD-1 mice.
