Description
PT-141 (Bremelanotide) is a synthetic cyclic heptapeptide with the sequence Ac-Nle-c[Asp-His-D-Phe-Arg-Trp-Lys]-OH, molecular formula C₅₀H₆₈N₁₄O₁₀, a molecular weight of approximately 1,025.18 Da, and CAS number 189691-06-3. PT-141 is a C-terminal hydrolysis derivative of Melanotan-2 and binds at MC3R and MC4R subtypes of the melanocortin receptor family in research models.
In laboratory research, PT-141 is utilized in melanocortin receptor-mediated CNS signaling studies, hypothalamic neuropeptide pathway investigations, dopaminergic and oxytocinergic system interaction experiments, MC4R-dependent behavioral neuroscience models, cAMP production assays, β-arrestin recruitment studies (BRET/FRET-based), and functional-selectivity (biased-signaling) characterization at melanocortin receptor subtypes.
Supplied as a lyophilized powder with ≥99% purity verified by HPLC. For storage and handling conditions, refer to the Certificate of Analysis provided with each lot. This product is intended strictly for laboratory research use only (RUO) and is not for human consumption, therapeutic use, or any diagnostic purposes.
