Pinealon

Also known as EDR tripeptide, Glu-Asp-Arg, Epithalamin peptide fragment

Pinealon is a short synthetic tripeptide (Glu-Asp-Arg) developed by Professor Vladimir Khavinson at the St. Petersburg Institute of Bioregulation and Gerontology. It was isolated as an active fraction of Cortexin, a bovine cortex polypeptide extract. Pinealon is studied as a brain-specific bioregulator targeting neuroprotection, cognitive performance, and pineal gland function in aging models.

§ 01

Overview

Pinealon is a short synthetic tripeptide (Glu-Asp-Arg) developed by Professor Vladimir Khavinson at the St. Petersburg Institute of Bioregulation and Gerontology. It was isolated as an active fraction of Cortexin, a bovine cortex polypeptide extract. Pinealon is studied as a brain-specific bioregulator targeting neuroprotection, cognitive performance, and pineal gland function in aging models.

§ 02

Mechanism of action

Like other Khavinson short peptides, Pinealon is hypothesized to act as an epigenetic regulator by penetrating cell membranes and binding to GC-rich promoter regions in DNA, modulating transcription factor access and gene expression. Research has demonstrated that EDR upregulates expression of neuroprotective genes including nestin, GAP-43 (growth-associated protein 43), and superoxide dismutase (SOD). It reduces neuronal apoptosis in model systems, modulates the cholinergic system, and is thought to influence melatonin synthesis pathways in pinealocytes. The peptide crosses the blood-brain barrier by virtue of its small size.

Research summary

Russian clinical studies (primarily by Khavinson and colleagues) report improvements in memory, attention, perceptual-motor response times, and mental performance in elderly subjects given Pinealon cyclically. PMC-published research demonstrates neuroprotective effects in mouse models of Alzheimer's disease, with reduction in amyloid-related pathology and increased survival of hippocampal neurons. No large, double-blind, placebo-controlled trials in humans have been conducted outside Russia as of 2026.
