一般描述

[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.

应用

[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.

生化/生理作用

[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.

Subarachnoid hemorrhage (SAH) is still a major cause of morbidity and mortality. α-Melanocyte stimulating hormone (α-MSH) and other melanocortin peptides exert potent neuroprotective action and they might modulate key molecules involved in SAH-induced vasospasm. The aim of this research was

The incidence of malignant melanoma is rising more rapidly than that of any other cancer in the United States. The melanocortin 1 receptor (MC1R) is overexpressed in most human melanoma metastases, thus making it a promising target for imaging and

The highly hydrophobic fluorophore Laurdan (6-dodecanoyl-2-(dimethylaminonaphthalene)) has been widely used as a fluorescent probe to monitor lipid membranes. Actually, it monitors the structure and polarity of the bilayer surface, where its fluorescent moiety is supposed to reside. The present paper

Melanocortins (MC) trigger a vagus nerve-mediated cholinergic-antiinflammatory pathway projecting to the testis. We tested whether pharmacological activation of brain MC receptors might protect the testis from the damage induced by ischemia-reperfusion. Adult male rats were subjected to 1-h testicular ischemia
