Potent agonist of the nociceptin (ORL1) receptor, demonstrated both in vitro and in vivo. Selective, competitive antagonism at the nociceptin receptor has also been reported (pA2 = 7.02 and 6.75 in the guinea pig ileum and mouse vas deferens respectively)
Adrenocorticotropic Hormone (ACTH) (1-39), rat, is a potent melanocortin 2 (MC2) receptor agonist. During in vitro incubation with membrane preparations, peptide fragments of ACTH (1-39) were formed and subsequently isolated by high-pressure methods.
a-MSH, amide is a peptide with the sequence Ac-Ser-Tyr-Ser-Met-Glu-His-Phe-Arg-Trp-Gly-Lys-Pro-Val-NH2, MW= 1664.9. The melanocyte-stimulating hormones (collectively referred to as MSH or intermedins) are a class of peptide hormones that are produced by c
