Compound Overview
PT-141 is a synthetic cyclic peptide analog structurally derived from melanocortin-related peptide sequences. It contains a lactam bridge forming a constrained cyclic core and includes an N-terminal acetyl group with norleucine substitution, contributing to defined conformational stability and receptor-binding characteristics in laboratory analysis.
In laboratory research contexts, PT-141 is evaluated for receptor-binding characterization, peptide stability profiling, and analytical detection using chromatographic and mass spectrometry workflows under controlled experimental conditions. Experimental literature describes its classification within melanocortin receptor–targeting peptide analog systems studied in vitro and in preclinical animal models. All data referenced on this page is derived from published preclinical animal and in vitro studies. No human clinical trials have established approved uses for PT-141 as a research compound.

Compare to Related Compounds
Melanotan 1
- PT-141 is a cyclic melanocortin analog containing a constrained lactam bridge structure, whereas Melanotan 1 is a linear melanocortin peptide analog with distinct sequence architecture.
- These compounds differ in molecular conformation, sequence length, and analytical identification profiles under validated laboratory workflows.
Oxytocin
- PT-141 is classified within melanocortin receptor–targeting peptide analog systems, whereas Oxytocin is a cyclic nonapeptide with a disulfide bond and a distinct receptor classification.
- Analytical differentiation is based on sequence composition, structural cyclization type, and chromatographic behavior during peptide characterization.
Handling & Storage
Lyophilized Stability:
When stored sealed in a dry environment protected from light, lyophilized peptide material may maintain chemical stability for up to 12 months at controlled room temperature. For maximum long-term preservation, storage at -20°C is recommended.
Post-Reconstitution Stability:
Following reconstitution under sterile laboratory conditions, the solution may maintain stability for up to 30 days when stored at 2–8°C. Minimize repeated freeze–thaw cycles and protect from light to preserve peptide integrity.
Handling:
Allow vial to equilibrate to room temperature before opening to prevent moisture condensation. Use sterile technique throughout preparation.
