what-enzyme-breaks-down-protein-into-peptides Peptide 401, also recognized as Mast Cell Degranulating Peptide (MCDP), is a notable compound derived from bee venom. Its primary function revolves around its potent ability to induce mast cell degranulation, a process that releases histamine and other inflammatory mediators. This mechanism underlies its significant anti-inflammatory activity, making it a subject of considerable scientific interest for its potential to suppress increased vascular permeability and inflammatory responses.

Its linear formula is indicated as C110H192O25N40S4, and its CAS number is 32908-73-9ANTI‐INFLAMMATORY PROPERTY OF .... While primarily studied for its degranulating properties, its classification also extends to being an antimicrobial peptide (AMP).
The core mechanism of Peptide 401 involves its interaction with mast cells, leading to their degranulation. This process is crucial for releasing various substances, including histamine, which plays a significant role in allergic reactions and inflammation.Potent anti-inflammatory agent. At low concentrations, mediates the degranulation of mast cells thus evoking an inflammatory response. By mediating degranulation, Peptide 401 can evoke an inflammatory response, but paradoxically, at specific concentrations, it has demonstrated a potent ability to suppress inflammationMultifunctional Peptide-Drug Conjugate Corm-401@R9. Studies have shown that Peptide 401 can substantially inhibit edema provoked by injections of substances like carrageenin, suggesting a direct anti-inflammatory effect. Furthermore, research indicates that its anti-inflammatory activity might be partially attributed to the inhibition of prostaglandin synthesis. The effectiveness of Peptide 401 in combating inflammatory processes has also been linked to its ability to suppress increased vascular permeability, a common hallmark of inflammation.
The anti-inflammatory activities of Peptide 401 have been a focus of scientific research for decadesAKT Peptide (000-000-401). Early studies in the 1970s and 1990s explored its effects on edema and inflammatory responses in animal models. Investigations have also examined its relationship with other compounds, such as compound 48/80, which also induces histamine release, and its interaction with histamine receptor antagonists like mepyramine.
While Peptide 401 originates from bee venom, its scientific exploration extends to understanding its potential applications. Its properties as a mast cell degranulating factor and its potent anti-inflammatory effects make it a valuable tool in biological and pharmacological research. It's important to note that while extensively studied in research contexts, its direct therapeutic applications in humans are not widely established, and it is often supplied for scientific research purposes.
For researchers utilizing Peptide 401, proper handling and storage are crucial to maintain its integrity.Mast cell degranulating peptide - PubChem - NIH In its lyophilized form, it is typically stable for approximately 3-6 months when stored at 0-5°C. After rehydration, solutions are best used shortly after preparation, with recommended storage at +4°C for up to 5 daysPeptide 401. For longer-term storage of rehydrated peptide, -20°C for 6 months or -80°C for up to a year may be suitable, depending on the specific formulation and supplier recommendations.Storage:Up to 6 months in lyophilized form at 0-5°C. For best results, rehydrate just before use. After rehydration, keep solution at +4°C for up to 5 days ...
The study of Peptide 401 often intersects with research on other peptides and biological processes. For instance, its structural similarity to apamin, another bee venom peptide, highlights the diverse bioactivities found within venomous secretions. The concept of mast cell degranulation is central to understanding allergic responses and inflammation, and Peptide 401 serves as a model compound for studying these mechanisms. Additionally, research into antimicrobial peptides (AMPs) recognizes Peptide 401 as one such example, underscoring its multifaceted nature. The broader field of peptide research also encompasses peptides like Hyaluronan mediated motility receptor 393-401, indicating the vast array of peptides with specific biological roles being investigatedPeptide 401 | Histamine Receptor拮抗剂 - invivochem.cn.
