Cat. No. 1239
Biological ActivityHigh affinity ligand for the NOP site (Ki = 1.5 nM). Antagonizes nociceptin-stimulated GTP binding in rat brain and the chronotropic effect of nociceptin on rat cardiomyocytes. However, displays potent agonist properties in vivo, inhibiting locomotor activity in mice.
(Modifications: Arg-1 = N-terminal Ac, Lys-6 = C-terminal amide)
