PEP51™
PEP51™
PEP51 specifically targets cannabinoid-related pathways involved in neuroinflammation and neuronal signaling, representing a new, largely unexplored, therapeutic opportunity.
PEP 51 is a proprietary peptide derived from Hemopressin (a peptide generated during the normal recycling of proteins through the cell’s ubiquitin-proteasome system). While these molecules were believed for decades to be simple byproducts of protein degradation, growing evidence shows that many act as powerful regulators of cellular signaling.
How it works
Mechanistic studies indicate that PEP 51 interacts strongly with cannabinoid receptors. These receptors play a central role in regulating immune and inflammatory responses in the nervous system and peripheral tissues, as well as induces neuronal growth. By interacting with this signaling network, PEP 51 supports the reduction of key inflammatory cytokines. This specific interaction with the endocannabinoid system helps explain the peptide’s dual neuro-supportive and anti-inflammatory effects.
Challenge: Developing next-generation treatments for a variety of neurological and neurodegenerative disorders requires molecules that can cross biological barriers and interact with complex signaling networks.
Solution: PEP 51 utilizes the cell's own molecular language to target disease pathways through neuro supportive potential and anti-inflammatory properties.
Findings: By combining cannabinoid-modulating properties with strong neurological function, PEP 51 is positioned as a candidate for the development of new therapies targeting brain health.

Challenge: There is a critical need for highly effective oral therapeutic candidates that can significantly delay or prevent the onset of seizures.
Solution: Researchers evaluated the effects of orally administered NFKF, the peptide fragment that forms the basis of Pep51, in a mouse model of pilocarpine-induced epilepsy.
Findings: Preclinical studies demonstrated that NFKF delayed the onset of seizures with approximately 100-fold greater potency than cannabidiol.

Challenge: Neuroinflammatory diseases often result in poor neurological scores and impaired locomotor function, requiring innovative treatments where current options remain limited. Solution: PEP 51 was administered orally
Findings: Mice treated with PEP 51 showed significantly improved neurological scores and better locomotor activity compared with control or untreated animals.
