PT-141 10mg

PT-141 (Bremelanotide) — Cyclic Melanocortin Receptor Agonist

PT-141, also known as bremelanotide, is a synthetic cyclic heptapeptide analog of alpha-melanocyte-stimulating hormone (α-MSH). It acts as a non-selective agonist at melanocortin receptors with notable activity at MC3R and MC4R. Originally derived from work on Melanotan-II, PT-141 has been characterized in more than two decades of preclinical and clinical research examining its action on central melanocortin-receptor pathways and inflammatory signaling.

Mechanism of Action

PT-141 activates melanocortin receptors in the central nervous system, with particularly well-characterized binding to MC4R in the hypothalamus. Preclinical studies show its activation of MC4R modulates dopaminergic signaling in the medial preoptic area, influencing central melanocortin-receptor circuitry distinct from peripheral signaling mechanisms. Additional research has examined its anti-inflammatory action in hemorrhagic shock and ischemia-reperfusion models, mediated through MC1R activation.
