Melanocortin Receptor Agonist
A synthetic cyclic peptide heptapeptide and analog of α-MSH that acts as a non-selective agonist of melanocortin receptors, with notable activity at MC4R. Studied in preclinical and clinical literature for its central nervous system effects on behavioral pathways.
In published research, PT-141 has been administered subcutaneously and intranasally, with dosing in the low-milligram range and time-to-onset measured across multiple-hour windows.
The neuroendocrinology community has been particularly drawn to PT-141 because it acts upstream of vascular mechanisms — engaging central melanocortin circuits rather than peripheral hemodynamics. This positions it as a research probe for studying the hypothalamic neural basis of behavioral states distinct from receptor families targeted by other classes of compounds.
