P21 Peptides

P21 Peptides is a biomimetic short peptide that has undergone dual structural modifications-terminal acetylation and amidation-featuring a well-defined and stable amino acid sequence (Ac-DGGLAG-NH₂). Its core active ingredient is the modified P21 biomimetic peptide, with high-purity grades containing ≥98% effective active content, ensuring precise molecular structure and consistent activity. P21 Peptides appears as a standard pure white powder with fine, light texture and uniform fluffiness; the high-purity formulation above 98% results in an even more pronounced fluffy consistency. The product has virtually no irritating odor, with only a faint, natural amino acid scent detectable upon close sniffing. This characteristic significantly enhances its compatibility with various formulations, as it does not interfere with the base flavor or fragrance system of the final product, making it one of the most olfactory-compatible peptide ingredients available. P21 Peptides exhibits excellent water solubility and is suitable for the vast majority of water-based systems. At room temperature, it dissolves rapidly in pure water and glycerin aqueous solutions-complete dissolution occurs within 30 seconds under slight stirring, eliminating the need for prolonged standing. It is insoluble in oils and mineral oil systems.

P21 can effectively activate brain neurotrophic factors, promote the proliferation of hippocampal neurons, increase the density of dendritic spines, and enhance synaptic plasticity. It can precisely improve cognitive impairments caused by aging and pathology, effectively alleviate memory decline and decreased learning ability. It can also reduce excessive phosphorylation of tau protein and accumulation of β-amyloid protein in the brain, alleviate brain pathological damage, and have a good repair and protective effect on nerve cell damage caused by cerebral ischemia and nerve trauma. It can also moderately regulate neural status, relieve anxiety and depression-related neural stress responses.

P21 has an outstanding ability to protect cells throughout the body. It can stabilize the mitochondrial membrane potential, block the activation of the apoptotic pathway, and reduce cellular damage and apoptosis under various stress conditions at their root causes. For key organs and tissue cells such as vascular endothelium, it can form a long-lasting protective barrier, effectively resisting ischemia-reperfusion injury and cellular damage caused by external stimuli, maintaining normal physiological activity and metabolic functions of cells, and significantly enhancing the cell's stress resistance ability.

P21 can eliminate excessive oxidative free radicals in the body, alleviate oxidative stress damage and resist cellular aging. It can also repair the vascular endothelium and epithelial tissue barriers, reduce tissue permeability, accelerate the self-repair of damaged tissues in the body, and maintain the homeostasis of body tissues.

P21 is widely used in the mechanism research and candidate drug development for diseases such as Alzheimer's disease, senile cognitive impairment, and brain atrophy. It is also suitable for preclinical research of drugs for brain trauma and nerve injury repair.

P21 focuses on research related to functional decline due to aging, mainly conducting scientific experiments on cognitive decline in the elderly, aging of the body and mechanisms of cellular aging, as well as developing formulations for anti-aging functional preparations and nutritional supplements.
