α-MSH,酰胺(C77H109N21O19S1),序列为Ac-Ser-Tyr-Ser-Met-Glu-His-Phe-Arg-Trp-Gly-Lys-Pro-Val-NH2,分子量为1664.9。促黑素细胞激素,统称为MS或intermedins,是一类由垂体中叶细胞产生的多肽激素。MSH的增加导致人变黑。怀孕期间促黑素增加,伴随着雌激素的增加,引起孕妇色素沉着增多。库欣综合征是由于过量促肾上腺皮质激素(ACTH)导致色素沉着过度,例如腋窝黑棘皮症。大多数患有原发性阿狄森氏症的患者皮肤变黑(色素沉着过度),包括不暴露在太阳的部位,特征是皮肤皱折(例如手中)、乳头及脸颊(颊粘膜)的内部,旧疤痕可能会变暗。这是因为促黑素(MSH)和促肾上腺皮质激素(ACTH)具有相同的前体分子阿黑皮素原(POMC)。
促黑素是黑皮质素的一员,包括促肾上腺皮质激素、α-促黑素细胞激素(α-MSH)、(β-MSH)和(γ-MSH),这几个多肽是由前体肽阿黑皮素原(POMC)裂解的产物。α-MSH是色素沉着中最重要的黑皮质素。

Applications |
α-MSH given systemically effectively alleviated acute inflammatory reactions induced by an irritant (picryl chloride 0.5% in acetone) applied to the ear. The relative inhibition (percent of percent change) with α-MSH was virtually the same in both IL-10–deficient and in control animals (approximately 70%). α-MSH modulated all forms of inflammation by acting on peripheral inflammatory cells, glial inflammatory cells, and on central nervous system receptors that activate descending anti-inflammatory neural pathways. |
