PT-141 (Bremelanotide) is a reference synthetic cyclic peptide derived from α-MSH (α-melanocyte stimulating hormone). Its cyclic structure (disulfide bridge) increases its resistance to enzymatic degradation compared to linear analogs, making it a stable subject for in-vitro receptor studies.
Investigated biochemical pathways (academic context)
-
Melanocortin receptor activation: in-vitro binding assays on cloned MC1R, MC3R, MC4R, and MC5R; affinity to MC4R expressed in hypothalamic cell lines.
-
CNS pathway investigation: in-vitro models of interaction with dopaminergic and oxytocinergic signaling systems in isolated neuronal cultures.
-
Neuroendocrine academic research: referenced in studies of the melanocortin system in the context of energy homeostasis and inflammatory responses at the cellular model level.
-
Structural stability: characterization of the conformational stability of the cyclic peptide by HPLC and MS methods.
Laboratory use and storage
Suitable as a reference standard for HPLC, MS, and in-vitro receptor assays. In laboratory practice, lyophilized peptides are handled using appropriate sterile media. A compatible solvent intended exclusively for research purposes can be found in our offer as Bacteriostatic Water - 10 ml. Store the lyophilized powder at -20 °C, protected from light.
