Technical Overview: PT-141 (Bremelanotide) Specifications & Reconstitution

PT-141, chemically known as Bremelanotide, is a synthetic cyclic heptapeptide analog of Alpha-Melanocyte-Stimulating Hormone (alpha-MSH). Unlike traditional receptor-targeted compounds, this peptide acts as a non-selective agonist at central melanocortin receptors, primarily MC3R and MC4R within the central nervous system.

Physicochemical Profile & Storage Requirements

• Sequence: Ac-Nle-cyclo[Asp-His-D-Phe-Arg-Trp-Lys]-OH
• Molecular Formula: C50H68N14O10
• Molecular Weight: 1025.2 g/mol
• Purity Threshold: > 98% confirmed via High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS)
• Lyophilized Storage: Store raw lyophilized powder at -20°C in a desiccated environment away from light exposure.

Reconstitution Protocol & Concentration Calculations

To maintain structural integrity during laboratory handling, proper reconstitution procedures must be observed using sterile PT-141 reconstitution water UK grade supplies (0.9% Benzyl Alcohol Bacteriostatic Water).

1. Allow the lyophilized vial and bacteriostatic water to equilibrate to room temperature before reconstitution.
2. Sanitize the rubber stopper with an isopropyl alcohol wipe.
3. Using a sterile syringe, slowly introduce 1 mL or 2 mL of bacteriostatic water down the inside glass wall of the vial to avoid agitating the lyophilized cake.
4. Gently swirl the vial until the peptide is fully dissolved into a clear solution. Do not shake or vortex the vial, as mechanical stress can degrade cyclic peptide bonds.
5. Once reconstituted, store the liquid solution between 2°C and 8°C. Reconstituted peptides should be used within 30 to 45 days.

Reconstitution Volume	Lyophilized Mass	Resulting Concentration
1.0 mL Bacteriostatic Water	10 mg PT-141	10 mg/mL (1000 mcg per 0.1 mL)
2.0 mL Bacteriostatic Water	10 mg PT-141	5 mg/mL (500 mcg per 0.1 mL)
1.0 mL Bacteriostatic Water	5 mg PT-141	5 mg/mL (500 mcg per 0.1 mL)
