β-msh

beta-MSH, human is an endogenous peptide hormone and neurotransmitter produced by pro-opiomelanocortin (POMC), and is also an agonist of MC4-R (melanocortin 4 receptor).

Beta-MSH (1-22) (human) acetate (Beta-MSH (1-22) (human) acetate (17908-57-5 Free base)) , is an endogenous melanocortin-4 receptor (MC4-R) agonist.

Neuropeptide EI, rat acetate Displays functional MCH-antagonist and MSH-agonist activity in different behavioral paradigms.

β-Endorphin (β-EP) is an endogenous opioid neuropeptide with diverse biological activities. It is produced via piomelanocortin cleavage in the pituitary gland, hypothalamus, and in lymphocytes, then migrates to its sites of action which include plasma, gut, skin, placenta, cerebrospinal fluid, and cardiac tissues. β-EP induces concentration-dependent decreases in electrically stimulated contraction of the mouse vas deferens that can be reversed by the μ-opioid antagonist CTP and δ-opioid antagonist ICI 174,864. In vivo, β-EP (5 μg, i.c.v.) slows gastrointestinal transit in mice. β-EP (0.5 or 5 μg, i.c.v.) stimulates food intake in rats for 4 to 6 hours, however, this effect is not prolonged with continuous infusion. It antagonizes the appetite-suppressive effects of α-melanocyte-stimulating hormone (α-MSH) for the first three days post administration. β-EP also reduces paralytic demyelination induced by the murine coronavirus MHV-JHM in immunocompetent, but not irradiated or immune-incompetent, mice and rats.

γ-1-MSH, amide acetate (72629-65-3 free base), a putative hormone in the N-terminal region of the ACTH/beta- endorphin (beta-EP) precursor protein, was studied by RIA with an antiserum against gamma 3-MSH in ACTH-producing mouse pituitary tumor cells, AtT-20/D16v.

β-Melanocyte Stimulating Hormone (MSH), human (Synonyms: Beta-MSH (1-22) (human)) β-Melanocyte Stimulating Hormone (MSH), human, a 22-residue peptide, acts as an endogenous melanocortin-4 receptor (MC4-R) agonist.
