Thymosin Alpha 1 (Thymalfasin)

Application:Pharmaceutical
CAS No:62304-98-7
Ingredients:Thymosin Alpha 1 (Thymalfasin)
Properties:Thymalfasin, also known as Thymosin Alpha 1, is a polypeptide compound with significant immunomodulatory activity, it plays a vital role in the human immune system, especially in enhancing Th1 immune response. Th1 immune response is an important line of defense for the body against intracellular pathogen infection. It effectively removes infected cells and promotes the proper development of inflammatory response by activating macrophages, natural killer cells (NK cells) and cytotoxic T lymphocytes. As a member of the thymosin family, Thymalfasin has a unique structure and powerful functions, it promotes the differentiation and maturation of T cells by acting on T cell receptors and their related signal transduction pathways, especially enhancing the activity of Th1 cells. Th1 cells can secrete cytokines such as interferon- (IFN- ) and interleukin-2 (IL-2), which not only further enhance the activity of Th1 cells themselves, but also activate other immune cells, such as macrophages, to form a powerful immune network to jointly resist the invasion of pathogens. In addition to promoting Th1 immune response, Thymalfasin also has a wide range of immunomodulatory functions, it can regulate the balance of T cell subsets, inhibit the over-activation of Th2 immune response, and help alleviate the occurrence of allergic reactions and autoimmune diseases. In addition, Thymalfasin can also promote the maturation and function of dendritic cells and enhance antigen presentation ability, thereby improving the body's recognition and elimination efficiency of pathogens.

Retatrutide 5mg/10mg/15mg/20mg/30mg

Application:Pharmaceutical
CAS No:2381089-83-2
Ingredients:Retatrutide
Properties:1) Triple receptor agonism: Retatrutide is a GGG triple agonist that can act on three receptors simultaneously: glucagon-like peptide-1 receptor (GLP-1R), gastric inhibitory peptide receptor (GIPR) and glucagon receptor (GCGR). This triple mechanism of action makes it excellent in controlling appetite, delaying gastric emptying and increasing energy expenditure. 2) Significant weight loss effect: Clinical trials have shown that Retatrutide is effective in weight loss. At the highest dose, participants lost an average of 24.2% weight in 11 months, which is far superior to the 15-20% weight loss effect of other GLP-1 receptor agonists currently on the market (such as Semaglutide and Tirzepatide). 3) Metabolic regulation: Retatrutide can not only effectively reduce weight, but also improve metabolic indicators. For example, it can significantly reduce glycosylated hemoglobin (HbA1c) levels and has a positive effect on blood sugar control in patients with type 2 diabetes. In addition, it may also have a beneficial effect on cardiovascular health, although this area still needs further research. 4) Long-term effect and convenience: Retatrutide has been modified by fatty acid acylation and can bind to albumin in the blood, thereby extending its half-life. This means that patients only need to inject once a week, which is more convenient to use.

Usage:1) Blood sugar control in type 2 diabetes: Tirzepatide significantly lowers blood sugar levels by activating GLP-1 and GIP receptors. It can stimulate insulin secretion, inhibit glucagon release, and delay gastric emptying, thereby effectively improving blood sugar control in patients with type 2 diabetes. It is suitable for patients who still cannot achieve ideal blood sugar control through diet, exercise and oral hypoglycemic drugs (such as metformin or sulfonylureas). 2) Weight management: Tirzepatide performs well in weight management, especially for obese or overweight patients with weight-related comorbidities (such as hypertension, dyslipidemia, hyperglycemia, etc.). It helps patients lose weight by increasing satiety, reducing appetite and delaying gastric emptying. Clinical studies have shown that Tirzepatide can significantly reduce body mass index (BMI) and improve metabolic status. 3) Improvement of cardiovascular health: Tirzepatide also has a positive effect on the cardiovascular system. It can reduce the risk of cardiovascular disease and improve blood pressure and blood lipid levels, thereby providing additional health benefits for diabetic patients. 4) Other potential applications: Although the main indications of Tirzepatide are type 2 diabetes and weight management, it also shows certain potential in the fields of neurological diseases (such as Alzheimer's disease, Parkinson's disease), skin repair, tumor treatment, etc. However, these applications still need further research and clinical trial verification.

LL-37 China

Application:Pharmaceutical
CAS No:154947-66-7
Ingredients:LL-37
Properties:1. Physical Properties Appearance: The pure product is usually a white or off-white lyophilized solid powder. Net Charge: Under normal bodily conditions (pH 7.4), it carries a strong positive charge of +6. This makes it highly attractive to negatively charged bacterial surfaces. Isoelectric Point (pI): Approximately 10.61. It is a strongly basic polypeptide. 2. Spatial Structure Characteristics Chameleon-like Structure (Structural Plasticity): In pure water: It has no fixed shape and a loose structure, mainly in a random coil state. In the presence of salt or in contact with cell membranes: It rapidly twists into a very stable -helix structure. Perfect "Dual Nature" (Amphiphilicity): When it becomes an -helix, it exhibits dual affinity: The hydrophilic side: One side is lined with positively charged amino acids (lysine, arginine), which readily bind to water and bacterial surfaces. Hydrophobic surface: The other side is lined with water-averse amino acids (leucine, phenylalanine), which prefer to penetrate the lipid layer of bacterial cell membranes. 3. Environmental and Chemical Behavior Characteristics Concentration-dependent "aggregation" (oligomerization): At low concentrations (below 10 M), it prefers to work alone in solution (monomer form). At high concentrations or in saline environments, it aggregates in groups (forming dimers or tetramers). This aggregation behavior protects it from easy degradation by enzymes in the body. Salt sensitivity: The salt ion composition in solution alters its spatial shape. High concentrations of salt act as a shield, blocking its positive charge, thus slightly reducing its direct bactericidal rate, but not affecting its ability to call on immune cells. Protein resistance: Compared to other common peptides, LL-37 exhibits strong resistance to degradation by human proteases when bound to cell membranes, allowing it to survive longer in inflamed wounds.

This indicates that it plays an extremely fundamental and indispensable role in living organisms. Family Lineage: It belongs to the same family as glucagon and secretin, sharing similar structures but with different functional focuses. 2. Dual Identity: Both a "Hormone" and a "Neurotransmitter" Neurotransmitter/Neuromodulator: It is abundant in the central and peripheral nervous systems. Nerve endings release it to rapidly transmit "relaxation" signals between cells. Gastrointestinal Hormone: It is also released by endocrine cells in the intestines, regulating the secretion of digestive juices and muscle movement through blood circulation. This dual identity allows it to perfectly coordinate the nervous and digestive systems. 3. Biological Activity Characteristics: "Comprehensive Relaxation" and "Potential Anti-inflammatory Effects" These are the core clinical and experimental characteristics of VIP peptides: Potential Relaxant: It is one of the most potent smooth muscle relaxants in the body. It can relax blood vessels, trachea, and gastrointestinal muscles. Immune Brake (Anti-inflammatory): It is known as an "endogenous anti-inflammatory peptide." When the body's immune system is overactivated (such as during a cytokine storm), VIP peptides can inhibit the release of harmful substances (pro-inflammatory factors) from macrophages and T cells, while promoting the secretion of protective substances (anti-inflammatory factors). Neuroprotection: It can protect neurons in the brain from damage caused by toxins and inflammation.

DSIP China

Application:Pharmaceutical
CAS No:62568-57-4
Ingredients:DSIP
Properties:DSIP peptide ( -sleep-inducing peptide), a classic natural nonapeptide, is unique primarily due to its special structural design, central nervous system hurdle-crossing ability, and unique biological characteristics. We can summarize its core features into the following four aspects: 1. Structural and Physical Characteristics: Small and Extremely Soluble Ultra-small molecular structure: It consists of only 9 amino acids. Compared to the 28 amino acid VIP peptide, DSIP's structure is much simpler, with a molecular weight of only 848.8 g/mol. High water solubility and stability (powder state): As a short peptide, its white lyophilized powder state exhibits excellent water solubility. Its chemical structure is very stable and does not easily denature under a dry, light-protected environment at -20 C. 2. Pharmacokinetic Characteristics: Hurdle-crossing ability and rapid metabolism Excellent blood-brain barrier permeability: This is the most crucial physicobiological characteristic of DSIP. Most peptides, due to their large molecular size, have difficulty entering the brain from the bloodstream. DSIP, however, can cross the blood-brain barrier (BBB) relatively freely, acting directly on the central nervous system, which is a major prerequisite for its precise sleep regulation. Extremely short in vivo lifespan: Similar to VIP peptides, DSIP has a very short half-life in the bloodstream (only a few minutes). After entering the body, it is rapidly broken down and degraded by aminopeptidases in the blood and tissues. 3. Biological characteristics of action: "Smoothing" rather than "forcing" Non-sedative induction: This is its biggest difference from ordinary sleeping pills (such as benzodiazepines). DSIP does not forcibly paralyze nerves, nor does it change the normal sleep structure (e.g., it does not suppress REM sleep). It works by "smoothing" brain waves, inducing the brain to produce slow waves (Delta waves), allowing the body to enter deep sleep in accordance with its natural biological clock. A bidirectional regulator: It not only helps with sleep but also helps maintain wakefulness during the day. It functions more like a "clock regulator," bidirectionally regulating neurotransmitter release based on the body's diurnal environment, exhibiting strong adaptogen characteristics. 4. Powerful "Stress Resistance" and "Drug Resistance" Characteristics HPA Axis Protector: DSIP possesses a powerful "braking" effect when facing acute mental or physical stress. It inhibits the release of corticotropin-releasing factor (CRF) from the hypothalamus, thereby preventing a surge in stress hormones (cortisol). No Tolerance or Addiction: In animal studies, long-term administration of DSIP peptides did not induce dependence (addiction) like with traditional drugs, nor did it trigger rebound insomnia upon discontinuation.
