Literature
Research context
Bremelanotide differs from melanotan II by a free C-terminal carboxylate, which shifts the receptor-selectivity profile toward MC4R and MC3R and largely removes MC1R-driven pigmentation activity. Published work covers central melanocortin circuitry in rodents, receptor binding constants, and structure-activity comparisons across the cyclic lactam melanocortin series.
