The term "PT 131 peptide" can refer to several distinct entities within scientific and medical contexts, but most commonly, it is associated with PT-141, also known as bremelanotide. This synthetic peptide has gained attention for its role in enhancing sexual desire and treating sexual dysfunction in both men and womenAutomated solid-phase peptide synthesis to obtain .... While PT-141 is the primary interpretation driving many searches, other peptides, such as MTP-131 (elamipretide) or peptides labeled with Iodine-131, also appear in research literature, leading to potential confusion2025年12月25日—Synthesis of (131)I-rituximab resulted in a yield of 60%, with a radiochemical purity greater than 99%.

PT-141, or bremelanotide, is a peptide that acts as an agonist of the melanocortin receptors in the brain, specifically MC3R and MC4R. Unlike treatments that target the vascular system, PT-141 directly influences the central nervous system to boost libido and sexual arousal. It is considered a non-hormonal peptide, distinguishing it from other therapies.作者：ET Son·2021·被引用次数：28—2021;131(21):e146771.https://doi.org/10.1172/JCI146771. See the related ... 2014;127(pt13):2885–2897. View this article via: PubMed Google Scholar. PT-141 is primarily used to treat hypoactive sexual desire disorder (HSDD) in premenopausal women and erectile dysfunction in men.
Mechanism of Action:
PT-141 works by binding to melanocortin receptors in the hypothalamus, a region of the brain that plays a crucial role in regulating sexual behavior and desire. This activation leads to increased sexual thoughts and arousal.α-Lactalbumin Hydrolysate Stimulates Glucagon-Like ...
Administration and Dosage:
PT-141 is typically administered via subcutaneous injection. Dosage recommendations can vary, and it is essential to follow medical guidance. For women diagnosed with HSDD, the recommended dose is often 1.75 mg injected subcutaneously about 45 minutes before anticipated sexual activity. For men experiencing erectile dysfunction, dosages may differ. It is crucial to consult with a healthcare provider to determine the appropriate dosage and administration schedule for individual needsVasoactive Intestinal Peptide, Human, Porcine, and Rat.
Potential Side Effects:
While generally considered effective, PT-141 can cause side effects. The most common include nausea, flushing, headache, and injection site reactions作者：R Lin·2021·被引用次数：16—Our study demonstrates for the first time that the iodine-131(131I)-labeled caerin 1.1peptidecan inhibit CAL-62 tumor growth and migration..

Citations and Identifiers:
The number "131" can also appear as part of publication identifiers, citation formats (e.α-Lactalbumin Hydrolysate Stimulates Glucagon-Like ...g., volume, issue, or page numbers), or gene/sequence identifiers within scientific literature. For example, a paper might be cited as "131(21):e146771" or refer to a sequence like "SEQ ID NO:131." These instances do not represent a specific peptide but rather a reference within a research document or database.
When encountering the term "PT 131 peptide," it is most probable that the context refers to PT-141 (bremelanotide), a peptide known for its use in treating sexual dysfunction and enhancing libido. However, it is important to be aware that "131" can also signify other scientific entities, such as the mitochondria-targeting peptide MTP-131 or peptides labeled with the radioisotope Iodine-131, which have entirely different applications in medical research and treatment. Clarifying the specific context is essential to understanding the intended meaning and relevance of "PT 131 peptide."
