Dosing Information
Detailed Protocol
Administered via subcutaneous or intranasal injection. Intranasal delivery shows good brain penetration. Used preventatively or acutely after brain injury.
About P21
P21 is a synthetic peptide that was designed to inhibit interactions between DAPK1 and NMDA receptors, preventing excitotoxic neuronal death. It has shown neuroprotective effects in models of stroke, traumatic brain injury, and neurodegenerative diseases.
Research Notes
Developed as a neuroprotective agent for stroke and TBI. Research shows it prevents NMDA receptor-mediated excitotoxicity while preserving normal function.
