PT141: Research-Grade Peptide for Neuroendocrine and Sexual Function Studies

Explore the powerful applications of PT141, a high-purity peptide widely used in research on neuroendocrine function, sexual behavior, and melanocortin receptor pathways. Manufactured to rigorous quality standards and supported by a strong foundation of scientific literature, PT141 is an essential tool in laboratories investigating central nervous system signaling, sexual arousal mechanisms, and receptor pharmacology.

What is PT141?

PT141, also known by its chemical name Bremelanotide, is a synthetic peptide analog of α-MSH (alpha-melanocyte-stimulating hormone). It was developed to target melanocortin receptors in the brain, particularly MC3R En MC4R, which play a significant role in regulating libido, mood, and energy balance. Unlike other compounds that act through vascular pathways, PT141 acts directly on the centraal zenuwstelsel, making it a unique agent in neurobehavioral and sexual health research.

Originally derived from Melanotan II, PT141 has gained attention for its receptor specificity and central mode of action. It is currently the only compound of its kind that has received FDA approval (under the name Vyleesi) for the treatment of hypoactive sexual desire disorder (HSDD) in premenopausal women, further highlighting its importance as a research molecule.

Scientific Research & Mechanism of Action

PT141 works by activating melanocortin receptors in the brain, particularly MC3R En MC4R. These receptors are involved in sexual arousal, eetlustregulatie, stress response, En energy homeostasis. When PT141 binds to these receptors, it initiates a cascade of neurotransmitter responses that influence behavior, motivation, and mood, particularly via dopaminergic and hypothalamic pathways.

Key areas of research interest include:

• Hypoactive Sexual Desire Models
• Neuroendocrine Signaling Studies
• Melanocortin Receptor Pharmacodynamics
• Dopaminergic Activation and Reward Response
• Central Nervous System Modulation

Unlike PDE5 inhibitors that require peripheral arousal signals (like nitric oxide), PT141 has been shown in preclinical models to influence sexual motivation directly via neural circuits, making it a unique subject of CNS-focused sexual function research.

Benefits in Research Settings

• ✅ Targets the central nervous system rather than the vascular pathways
• ✅ Offers unique MC4R and MC3R receptor selectivity
• ✅ Highly stable in lyophilized form
• ✅ Rapid onset and short half-life make it suitable for controlled dosing models
• ✅ Supports studies on stress, appetite, and reward behavior in addition to sexual function

PT141’s profile makes it especially valuable for researchers studying multi-system interaction between hormonal, neurological, and behavioral pathways.

Storage and Reconstitution

• After reconstitution: Store at 2–8°C and use within 30 days
• Solvents: Sterile bacteriostatic water (BAC water) or sterile saline
• Houdbaarheid: 24 months from production (lyophilized)

Safety and Handling

PT141 is supplied for laboratory research use only. It is not approved for human or veterinary use, drug development, or diagnostic procedures. Handle under appropriate safety conditions and dispose of according to local chemical waste guidelines.

Hoe te gebruiken

PT141 is commonly reconstituted in sterile water for injection (SWFI) or bacteriostatic water and administered subcutaneously in controlled animal studies. Dosage and protocol will vary based on study design, species, and purpose. Always consult appropriate institutional guidelines and ensure protocols are approved by relevant ethical boards (e.g., IACUC, IRB).
