    2. Product Introduction & Features

        P21 (also known as P021) is a synthetic adamantane-modified tetrapeptide derived from the active fragment of Ciliary Neurotrophic Factor (CNTF 148-151). It features N-terminal acetylation and C-terminal adamantane modification, which greatly enhances blood-brain barrier (BBB) permeability and metabolic stability compared with natural full-length CNTF. This peptide effectively promotes neurogenesis, inhibits neuroinflammation, reduces β-amyloid deposition and abnormal tau protein aggregation, widely used in preclinical research on cognitive improvement, brain injury repair, neurodegenerative diseases and neural pathway regulation.
