α-Melanocyte-Stimulating Hormone (MSH), amide 是一种内源性神经肽，具有抗炎解热作用。α-MSH 是前阿黑皮素原翻译后的衍生物，是黑皮质素受体 4 (MC4R) 内源性的激动剂。
α-Melanocyte-Stimulating Hormone (MSH), amide is an endogenous neuropeptide, with anti-inflammatory and antipyretic activities. α-MSH is a post-translational derivative of pro-opiomelanocortin (POMC), acts as an endogenous melanocortin receptor 4 (MC4R) agonist.

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。

Alpha-MSH is a peptide that binds to the Melanocortin 1 receptor. Alpha-MSH is a peptide hormone and neurotransmitter that is involved in the regulation of numerous physiological processes, including appetite, sexual desire, immune response, and skin pigmentation. In addition to its role as a natural hormone, it has been studied as a potential drug for the treatment of obesity and other diseases. The product can also be used as an antibody probe for Western blotting or immunohistochemistry.\xa0 The product is produced synthetically.
