Melanocortin receptor agonist (Bremelanotide)
COP 310.000
PT-141 (bremelanotide) is an investigational synthetic cyclic peptide that acts as a melanocortin receptor agonist. It is being studied in areas such as melanocortinergic signaling in the central nervous system, sexual behavior, and appetite regulation. It is supplied as a 10 mg vial of lyophilized powder, intended exclusively for scientific research.
PT-141, also known as bremelanotide, is an investigational synthetic cyclic peptide derived from alpha-MSH (melanocyte-stimulating hormone). It acts as a non-selective agonist of melanocortin receptors, with primary affinity for the MC3R and MC4R subtypes.
Unlike other compounds in its family, it is studied for its action on pathways of the central nervous system and not for its effect on pigmentation. It is used as a reference compound in experimental models of melanocortinergic signaling.
At KaiLab, peptides are supplied as a freeze-dried powder intended exclusively for scientific research. It is not approved for human or veterinary use.
These recommendations apply to all KaiLab freeze-dried peptides.
Freeze-dried powder (not reconstituted):
– Store at −20 °C for long-term storage.
– Protect from light and keep in a dry environment.
– Under these conditions it maintains its stability for extended periods.
Reconstituted (in solution):
– Reconstitute routinely with bacteriostatic water, under laboratory conditions.
– Store refrigerated (2°C to 8°C).
– Avoid repeated freezing and thawing cycles.
– Handle with aseptic technique and appropriate laboratory equipment.
These instructions pertain solely to the handling of research materials.
PT-141 is primarily studied in areas related to melanocortinergic signaling:
– Melanocortin receptors MC3R and MC4R
– Pathways of the central nervous system associated with sexual behavior
– Regulation of appetite and energy balance
– Hypothalamic signaling
– Hemodynamic responses in experimental models
