PT-141

PT-141, also known as Bremelanotide, is a synthetic cyclic heptapeptide supplied for controlled laboratory, analytical, and scientific research.

Its molecular identity includes N-terminal acetylation, norleucine, D-phenylalanine, and an intramolecular lactam ring formed between the Asp and Lys side chains. These structural features are integral to accurate chemical identification and distinguish PT-141 from conventional linear peptides.

For final technical documentation, the exact salt or counter-ion form, purity specification, and lot-specific analytical profile should be confirmed using the applicable Certificate of Analysis.

Research Applications

PT-141 may be examined in controlled non-clinical research involving:

• Cyclic peptide characterization
• Ligand-receptor interaction studies
• Molecular signaling research
• Modified amino-acid characterization
• Structure-function analysis
• Analytical peptide comparison
• Stability assessment
• Non-clinical biochemical and cellular models

Experimental observations should remain specific to the applicable research system and should not be interpreted as evidence of behavioral, reproductive, therapeutic, or clinical effectiveness.

Structural Information

PT-141 is commonly represented as:

Ac-Nle-c[Asp-His-D-Phe-Arg-Trp-Lys]-OH

Important structural characteristics include:

• Seven amino-acid residues
• N-terminal acetylation
• Norleucine residue
• D-phenylalanine residue
• Intramolecular lactam cyclization
• Free C-terminal carboxyl group

Because PT-141 contains non-standard residues, stereochemistry, and cyclization, a conventional one-letter sequence alone is not sufficient to describe its complete molecular identity.

Analytical Identification

Relevant analytical characterization may include:

• Peptide identity confirmation
• Molecular mass assessment
• Cyclization verification
• Modified-residue confirmation
• Stereochemical verification
• Chromatographic purity testing
• Structural characterization
• Lot-specific quality analysis

Specifications & Documentation

Lot-specific documentation should be reviewed for:

• Compound identity
• Peptide structure
• Molecular formula
• Molecular weight
• Modified residues
• Cyclization
• Terminal modifications
• Salt or counter-ion form
• Purity specification
• Analytical testing
• Lot or batch information
• Certificate of Analysis
• Storage requirements

Authenticated product-specific documentation should take precedence over generalized reference specifications.

Storage & Handling

Store according to the conditions specified on the product label and Certificate of Analysis. Protect the material from environmental conditions that could compromise peptide integrity.

Handling should follow established laboratory procedures appropriate for modified research peptide materials.
