General description

[Nle4, D-Phe7]-α-melanocyte stimulating hormone is a potent analogue of α;-melanocyte-stimulating hormone (α -MSH). αMSH is a tridecapeptide, mostly produced by the cells in the brain, pituitary and in circulation.

Application

[Nle4, D-Phe7]-α-Melanocyte Stimulating Hormone trifluoroacetate salt has been used to detect its effect on O2 consumption and CO2 production in C57BL/6 mice.1It is also used to determine its effect on leptin secretion in the primary cultures of differentiated adipocytes.

Biochem/physiol Actions

[Nle4, D-Phe7]-α-melanocyte stimulating hormone is 100 times more potent than α-MSH in stimulating melanoma tyrosinase, which is a rate limiting enzyme in melanin biosynthesis and is 26 times as potent as α-MSH in S91adenylate cyclase assay. α –MSH has an essential role to play in melanin production in animals. It also regulates development of several skin diseases, including cutaneous inflammation and hyper-proliferative skin diseases.
