PT-141 , also known as Bremelanotide, is a synthetic peptide that has attracted significant interest in the scientific community due to its unique properties and potential applications. PT-141 is a derivative of the melanocortin peptide hormone α-MSH (alpha-melanocyte-stimulating hormone). This peptide has been primarily studied for its effects on the central nervous system, particularly in relation to its interaction with melanocortin receptors.
Structural Composition and Mechanism of Action
PT-141 is designed to mimic the effects of α-MSH by binding to melanocortin receptors, specifically MC3R and MC4R. These receptors are found in various regions of the brain and are involved in numerous physiological processes, including sexual arousal, appetite regulation, and energy homeostasis. By activating these receptors, PT-141 exerts its effects on these functions.
The structural composition of PT-141 enables it to bind selectively to melanocortin receptors, leading to the activation of downstream signaling pathways. This activation results in various physiological responses, making PT-141 a valuable tool for research in multiple domains.

Researchers are particularly interested in how PT-141 interacts with melanocortin receptors in the brain to influence neural activity. Studies focus on understanding the molecular mechanisms through which PT-141 modulates these receptors and its potential implications for neurological research.
- Appetite Regulation: PT-141 has also been studied for its effects on appetite and energy balance. By binding to melanocortin receptors involved in appetite regulation, PT-141 can influence food intake and energy expenditure. Researchers are exploring how PT-141 modulates these processes and its potential applications in obesity and metabolic disorders research.
- Stress and Anxiety: Another significant area of research involves the role of PT-141 in modulating stress and anxiety responses. Melanocortin receptors are known to play a role in the body’s response to stress, and PT-141’s interaction with these receptors provides insights into its potential effects on stress and anxiety levels. Studies aim to uncover the underlying mechanisms and potential therapeutic applications for stress-related conditions.
- Cardiovascular Research: PT-141 is also of interest in cardiovascular research due to its effects on blood pressure and heart rate. By influencing the melanocortin system, PT-141 can modulate cardiovascular functions. Researchers are investigating how PT-141 impacts these parameters and its potential implications for cardiovascular health.
