ALPHA-MSH Chemische Eigenschaften,Einsatz,Produktion Methoden
Verwenden
alpha-Melanocyte Stimulating Hormone amide is an endogenous melanocortin receptor agonist (Ki values are 0.12, 31, 660 and 5700 nM for MC1, MC3, MC4 and MC5 receptors respectively). Anti-inflammatory peptide; antagonizes proinflammatory mediators, including TNF-α, IL-6 and NO and induces anti-inflammatory cytokine IL-10. Inhibits food intake and induces penile erections following i.c.v. administration.
Allgemeine Beschreibung
α-Melanocyte-stimulating hormone (α-MSH) is a tridecapeptide, mostly produced by the cells in the brain, pituitary and circulation. Pro-inflammatory cytokines or UV light induced epidermal cells such as keratinocytes and melanocytes synthesize and discharge α–MSH. Poopiomelanocortin (POMC) acts as a precursor for α-Melanocyte-stimulating hormone (α-MSH) production.

Its solubility in H2O is 1mg/mL. It is separated from the extract by ion-exchange on carboxymethyl cellulose, desalted, evaporated and lyophilised, then chromatographed on Sephadex G-25. [Lande et al. Biochemical Preparations 13 45 1971.]
