PT-141 (Bremelanotide)
PT-141 is a cyclic heptapeptide and the deaminated metabolite of melanotan II, acting as an agonist at melanocortin receptors with principal research interest at MC4R. Unlike melanotan II it lacks significant MC1R-mediated pigmentation activity, making it a cleaner tool for isolating MC4R-mediated central effects. Its mechanism is centrally mediated rather than vascular, which distinguishes it from PDE5-targeting compounds.
Research applications
- MC4R and MC3R binding and selectivity assays
- Central melanocortin pathway signaling studies
- Comparative receptor profiling against melanotan II
Storage
Store lyophilized at -20°C protected from light. Reconstituted at 2-8°C for up to 30 days.
Reconstitution
Reconstitute with bacteriostatic water down the vial wall. Swirl gently.
