Description
PT-141 (Bremelanotide) is a synthetic peptide analog of alpha-melanocyte-stimulating hormone (alpha-MSH), studied for its agonist activity at melanocortin receptors, particularly MC3R and MC4R subtypes expressed in the central nervous system.
In laboratory research, PT-141 is examined for its role in melanocortin receptor pathway activation and its downstream effects on centrally mediated signaling circuits, distinguishing it from peripherally acting compounds.
Researchers studying PT-141 often use it as a tool to investigate melanocortin receptor subtype selectivity and the broader signaling architecture of the melanocortin system, which is also implicated in energy homeostasis and pigmentation research.
Its structural relationship to Melanotan-class peptides makes PT-141 a frequent comparator in structure-activity research examining receptor subtype specificity across the melanocortin peptide family.
PT-141 is supplied strictly for laboratory research into melanocortin receptor pharmacology and central signaling pathways.
