Synthetic alpha-MSH analog that binds MC1R to stimulate melanogenesis, investigated for photoprotective properties in erythropoietic protoporphyria.
Application: Melanocortin
Melanocortin peptides act on the melanocortin receptor system (MC1R-MC5R), influencing melanogenesis and related physiological pathways. This category includes Melanotan II (non-selective MCR agonist) and PT-141 (Bremelanotide) (MC3R/MC4R agonist). These cyclic peptides have been studied for melanocyte stimulation and receptor binding affinity. Available at wholesale pricing with batch-specific HPLC and mass spectrometry verification from WholesaleBulkPeptides.
