How it relates to — and is not — other Khavinson bioregulators

Pinealon (this page) is the tripeptide Glu-Asp-Arg (EDR) on opened papers that print the trade name, and on opened PMID 35887081 Table 2. That catalog is a research-network taxonomy, not a receptor-class assignment.

03 / Overview

What is Pinealon?

Pinealon is the synthetic tripeptide Glu-Asp-Arg. Opened papers from the St. Petersburg Institute of Bioregulation and Gerontology and collaborators report four clusters of laboratory observations:

Cluster 2

Proposed DNA / nuclear interaction

FITC-labeled pinealon entered HeLa cytoplasm, nucleus, and nucleolus (Fedoreyeva 2011, PMID 22117547); later spectral / NMR / MD work on EDR-DNA with Mg2+ (Silanteva 2019, PMID 30762356); promoter-docking language for EDR (PMID 34071923; review PMID 33396470).

Cluster 3

Catalog docking and later EDR cell models

Trade name Pinealon often not printed. 5xFAD dendritic-spine study (PMID 34071923); LAT1 table row Pinealon (EDR), ICM -30.29 (PMID 35887081); later induced-neuron papers that co-test EDR with KED and AEDG (PMID 39518916).

Cluster 4

Small regional human observations

Meshchaninov et al. 2015 (PMID 26390612): 32 people aged 41-83 with polymorbidity and organic brain syndrome in remission received named Pinealon and Vesugen preparations. Bashkireva 2012 (PMID 23734521) is an occupational-medicine series that names pinealon and vezugen; not an NCT. Umnov 2013 (PMID 24738258) is a review, not a new trial.

Europe PMC REST query=pinealon returned hitCount 29 on 16 August 2026. Almost all originate from the Khavinson network. Independent Western replication of a receptor-level mechanism was not located. A well-validated receptor target is not established on any opened page.

The SRP index card (August 2026) already states this correctly: short peptide commonly described as Glu-Asp-Arg; a definitive receptor and full pharmacology are not established; most publications are preclinical or small and concentrated within a limited research network; large independent randomized trials are lacking; verify the three-amino-acid sequence.

Opened SRP product (16 August 2026): http://simpleresearchpeptides.com/product/pinealon-10-mg/ and http://simpleresearchpeptides.com/product/pinealon/. Dedicated pinealon-research-guide URL returned HTTP 404. Vendor dosage / reconstitution / injection copy on the product page is not reproduced here.

04 / Mechanism

Proposed research mechanisms (not confirmed clinical effects)

No opened paper establishes a classical receptor agonist/antagonist assignment for Pinealon.

ROS / viability. Opened PMID 21978084: pinealon (Glu-Asp-Arg) demonstrates dose-dependent restriction of ROS accumulation in cerebellar granule cells, neutrophils, and PC12 cells and decreases necrotic cell death measured by the propidium iodide test, with delayed ERK 1/2 activation and cell-cycle modification. Authors conclude that besides known antioxidant activity, pinealon is able to interact directly with the cell genome. That last sentence is the authors interpretation, not a crystal structure.

DNA / nuclear. PMID 22117547: FITC-pinealon produced fluorescence in HeLa cytoplasm, nucleus, and nucleolus; Stern-Volmer constants differed by oligonucleotide sequence; authors report preferential binding language for CNG / CAG-containing sequences. PMID 30762356: EDR can partly penetrate into the major groove of DNA and affect the base atoms, mainly the N7 and O6 of guanine; Mg2+ can promote DNA-EDR interaction. These are biophysical / cell-imaging results, not a validated receptor.

Docking. PMID 34071923: EDR docking to hexanucleotide DNA; authors list EDR binding-site language for CASP3, NES, GAP43, APOE, SOD2, PPARA, PPARG, GDX1 promoters. PMID 33396470 is a review that restates MAPK/ERK, caspase-3, p53, SOD2, GPX1, PPAR, serotonin, and calmodulin as proposed components. PMID 35887081 Table 2: Pinealon (EDR), ICM -30.29, labeled Neuroprotector. Docking / review, not a measured PEPT/LAT flux for Pinealon.

Hypoxia / aging rodent. PMID 18546825: among vilon, epitalon, vesugen, and pinealon, pinealon had the most pronounced antihypoxic effect in hypobaric hypoxia. PMID 21809624 and PMID 28976148: Pinealon vs Cortexin on behavior and caspase-3 after carotid occlusion or in Morris-maze learning. PMID 25051764 and PMID 28509493: Pinealon vs Cortexin on cytokines / caspase-3 / hypoxia-hypothermia in old rats. These are rodent model signals.

Not shown in a paper opened here: a registered ClinicalTrials.gov or WHO-ICTRP trial for Pinealon (NCT: none); a peer-reviewed randomized, placebo-controlled human efficacy trial; human pharmacokinetics; a modern receptor-panel Ki table or crystal structure; independent Western-laboratory replication of the ROS / nuclear-entry findings; FDA, EMA, or NCATS approval / UNII.

Do not treat as Pinealon evidence: Vesugen/KED-only endothelial papers; Livagen/KEDA liver papers; Epitalon telomerase papers; Cortexin-only extract papers; vendor blogs that assign a clinical indication; the SRP product-page educational dosage protocol.

Observed

Cell ROS / necrosis

PMID 21978084 cerebellar granule / PC12 / neutrophil models. Author genome-interaction sentence is interpretation.

Mechanism in one line. Short tripeptide printed as EDR; opened work is cell ROS/viability, biophysical DNA language, hypoxia-rodent panels, docking, and small same-network human observations. Not a receptor assignment. Not for human use.

Study design and handling (not human-use instructions)

Methodology-centered guidance for lawful laboratory research. The SRP product page contains a vendor dosage chart, reconstitution arithmetic, syringe-unit table, and injection-technique copy. That vendor protocol is not reproduced here and is not independent chemistry.

  • Identity and documentation. Record batch identity, analytical documentation, material condition, receipt date, and storage history before use. Confirm the three-residue sequence (Glu-Asp-Arg / EDR) and salt form. Do not treat the trade name as a substitute for molecular identification.
  • Controls and replication. Use appropriate vehicle, positive, and negative controls with predefined endpoints and adequate biological replication. If comparing bioregulators, include sequence-matched controls (KED, KEDA, AEDG, KE) rather than assuming tissue tropism.
  • Cold-chain handling. Follow the product label, batch documentation, and laboratory SOPs. Minimize uncontrolled temperature and light exposure. Do not copy consumer reconstitution charts into a research protocol without an analytical plan.
  • Transparent reporting. Document concentrations, preparation methods, model characteristics, exclusions, adverse observations, and complete outcomes. Report the actual sequence used, not only Pinealon.

09 / FAQ

Frequently asked questions

Is Pinealon approved for human use?

No. Pinealon is investigational and is not an FDA-approved drug for human treatment. Opened NCATS, openFDA, and IUPHAR queries returned no substance/ligand/label. UNII: none. NCT: none.

What type of evidence exists?

Preclinical / small human literature. Opened literature is mainly neuronal cell and hypoxia-rodent work, biophysical DNA interaction, in-silico docking, one 5xFAD mouse paper that uses the sequence name EDR, and small regional human observations. Almost all records sit in the Khavinson / St. Petersburg network. Controlled human evidence is insufficient to establish safety or effectiveness.

Is the sequence really Glu-Asp-Arg / EDR?

Yes, on opened papers that print the trade name next to that sequence (PMID 21978084; PMID 22567179; PMID 35887081 Table 2) and on papers that print T-33 (Glu-Asp-Arg) (PMID 22803085). CID 10273502 is the matching L-tripeptide (title Glu-Asp-Arg; synonym pinealon). SRP product page prints the same aliases as vendor language. Confirm the vial by sequence and assay.

How is this different from Vesugen, Livagen, Pancragen, or Epitalon?

Different sequences on opened pages: Vesugen KED; Livagen KEDA; Pancragen KEDW; Epitalon AEDG. PMID 35887081 Table 2 prints them as separate rows. PMID 34071923 and PMID 26390612 test or name Pinealon/EDR and Vesugen/KED as distinct materials.

Did any registered trial test Pinealon?

No opened registered trial. ClinicalTrials.gov API v2 query.term=pinealon returned totalCount: 0.

Does an animal or cell result predict a human outcome?

No. Animal and cell models are valuable for generating and testing hypotheses, but species differences, experimental conditions, exposure, and study quality limit direct translation.

How is this different from the product page?

This guide explains the evidence and its limitations. The product page provides batch, purchasing, and research-material information, plus vendor protocol language that this educational page does not repeat. A research product is not an approved medicine.

Can SRP vials be used as a human dose substitute?

No. SRP listings are for laboratory research only and are not for human or animal use. This page does not provide reconstitution, administration, or dosing instructions.
