用法：
黑素素1（被称为Afamelanotide）是肽激素的合成肽变体，称为α-黑素细胞刺激激素或MSH，其在体内天然产生，并且负责刺激黑素生成，这是皮肤色素沉着的肽过程。在发挥其作用的过程中，α-MSH激活某些黑皮质素受体。事实上，MSH还通过这些黑皮质素受体对脂质代谢，食欲和性欲进行有力的影响。结果，Melanotan-1无阳光皮肤晒黑效果。尽管黑素素2和PT-141作为治疗性功能障碍的潜在补救方法已经被深入研究，但已经广泛地研究了黑色素素1用于防止由于其黑素生成刺激性质而引起的阳光紫外线辐射的有害影响。
黑素素-1和黑霉素2都是趋于诱导皮肤鞣制的肽激素α-黑素细胞激素激素（α-MSH）的类似物。与黑醋酸1不同，黑素素2已被证明具有壮阳性，增加性欲的附加作用。黑素素-1是黑皮质素受体（MC1R，MC3-5R）的非选择性激动剂。作为α-MSH的类似物，其作用机理是天然哺乳动物鞣制过程的生物仿真。ning process.

Usage:
Melanotan 1 (alsoreferred to as Afamelanotide) is a synthetic peptide variant of a peptide hormone, called alpha-Melanocyte stimulating hormone or MSH that is naturally produced in the body and is responsible for stimulating melanogenesis, a peptide process for pigmentation of the skin. Alpha-MSH activates certain melanocortin receptors in the process of exerting its effects. Indeed, MSH also exerts potent influence over lipid metabolism, appetite, and sexual libido via these melanocortin receptors. As a result, Melanotan-1 sunless skin tanning effects. While Melanotan 2 and PT-141 have been studied at length as a potential remedies for the treatment of sexual dysfunction, Melanotan-1 has been researched extensively for use in protecting against the harmful effects of ultraviolet radiation from sunlight due to its melanogenesis-stimulating properties.
Both Melanotan-1 and Melanotan 2 are analogs of the peptide hormone alpha-melanocyte stimulating hormone (α -MSH) that tend to induce skin tanning. Unlike Melanotan 1, Melanotan 2 has been shown to have aphrodisiac properties, the additional effect of increasing libido. Melanotan-1 is a non selective agonist of the melanocortin receptors (MC1R, MC3-5R). As an analogue of α -MSH, its mechanism of action is biomimicry of the natural mammalian tanning process.nning process.ning process.
