What is P21-adamantane?

P21-adamantane is a modified neurotrophin-mimetic peptide derived from the CNTF (ciliary neurotrophic factor) sequence, with an adamantane moiety attached to enhance blood-brain barrier penetration and receptor engagement. Activates STAT3/JAK signalling and BDNF expression. Studied for hippocampal neurogenesis, cognitive enhancement, and neuroprotection models, with the adamantane modification providing superior CNS bioavailability compared to unmodified P21. Research use only.

Research Applications

Hippocampal Neurogenesis

Dentate gyrus progenitor cell proliferation, BrdU/EdU incorporation, DCX expression

BDNF Upregulation

BDNF mRNA and protein expression, TrkB signalling, CREB phosphorylation

STAT3/JAK Pathway Research

CNTF receptor complex activation, STAT3 nuclear translocation, target gene profiles

Blood-Brain Barrier Penetration

Adamantane moiety CNS uptake vs unmodified peptide — pharmacokinetic comparison

Cognitive & Memory Research

Morris water maze, novel object recognition, LTP modulation in rodent models

Frequently Asked Questions

How do I reconstitute P21-adamantane?
Add 1 mL bacteriostatic water to the lyophilized vial, directing liquid down the inner wall. Swirl gently until clear — takes 2–3 minutes due to the hydrophobic adamantane modification. Slight warming to 37°C can aid dissolution if needed.
How should P21-adamantane be stored?
Store lyophilized vials at −20°C. Reconstituted solution is stable at 2–8°C for up to 3 weeks. The adamantane moiety is susceptible to aggregation at high concentrations — avoid freeze-thaw cycling.
What is the significance of the adamantane modification in P21?
Adamantane is a lipophilic cage molecule that dramatically improves CNS penetration by facilitating passage through the blood-brain barrier. P21-adamantane shows superior hippocampal BDNF upregulation and neurogenesis compared to the unmodified P21 peptide in published research models.
