Melanotan I, Melanotan II and PT-141: the MC1R–MC5R receptor system, pigmentation signaling and central pathways
Melanocortin Peptides & Receptor Biology
Melanocortin peptides are a family of research compounds that engage the melanocortin receptor system — five G-protein-coupled receptors (MC1R through MC5R) distributed across skin, brain, adrenal, and immune tissue. Because a single receptor family influences pigmentation, energy balance, inflammatory signaling, and central arousal pathways, melanocortin analogues have become valuable tools for probing how one signaling axis produces such diverse biology.
