About P-21
- Molecular weight
- 578.7 g/mol
P021 is a small peptidergic compound derived from a biologically active region of human ciliary neurotrophic factor (CNTF, residues 148–151), corresponding to an Ac-Asp-Gly-Gly-Leu-Ala-Gly backbone bearing an adamantylated glycine and a C-terminal amide. In research models it is characterised as an enhancer of BDNF expression and studied for neurotrophic and neurogenic activity.
