Pinealon vs Epithalon: EDR and AEDG Compared

Pinealon and Epithalon are different peptides: Pinealon has the three-residue sequence Glu-Asp-Arg (EDR), while Epithalon has the four-residue sequence Ala-Glu-Asp-Gly (AEDG) (Sources: Pinealon sequence source, Epitalon reference record).

The catalog identifies separate laboratory materials: Pinealon research listing at Curo and Epithalon research listing at Curo.

Are Pinealon and Epithalon the same peptide?

No. Pinealon's Glu-Asp-Arg sequence contains three residues; Epithalon's Ala-Glu-Asp-Gly sequence contains four. EDR and AEDG identify these different sequences (Sources: Pinealon sequence source, Epitalon sequence record).

What is the difference between EDR and AEDG?

The reference properties for EDR and AEDG are recorded separately in PubChem (Sources: Pinealon PubChem record, Epitalon PubChem record).

What does each peptide's research focus on?

Pinealon: oxidative stress and neuronal experiments

The 2011 Pinealon paper examined ROS accumulation, necrotic cell death and ERK1/2 activation in cerebellar granule cells, neutrophils and PC12 cells. The 2012 paper examined spatial orientation and learning in rat offspring after prenatal hyperhomocysteinemia, plus ROS accumulation and necrotic cell counts in isolated cerebellar neurons (Sources: 2011 Pinealon cell study, 2012 Pinealon rat study).

The 2021 paper studied both EDR and KED in an Alzheimer's mouse model, focusing on dendritic-spine morphology and possible epigenetic mechanisms explored through molecular modelling (Source: 2021 EDR and KED mouse study).

Epithalon: telomerase and telomeres in fibroblast culture

The cited 2003 Epithalon paper measured telomerase-related changes in telomerase-negative human fetal fibroblast culture. Its author record lists V. Kh. Khavinson with the St. Petersburg Institute of Bioregulation and Gerontology (Source: 2003 Epithalon study and affiliation record).

The authors reported that Epithalon induced expression of the catalytic subunit of telomerase, telomerase enzymatic activity and telomere elongation in telomerase-negative human fetal fibroblast culture (Source: 2003 Epithalon fibroblast study).

The authors proposed reactivation of the telomerase gene as a possible explanation for these changes (Source: 2003 Epithalon mechanism hypothesis).

The Pinealon papers and the Epithalon fibroblast paper address different experimental questions: oxidative-stress responses and neuronal measures for Pinealon, and telomerase activity and telomere length for Epithalon (Sources: Pinealon cell study, Pinealon rat study, EDR and KED mouse study, Epithalon fibroblast study).

Why are Epithalon and Epitalon both used?

PubChem lists Epitalon, Epithalon and Epithalone as synonyms for CID 219042 (Source: PubChem alias record). FDA's substance record for UNII O65P17785G also maps Epithalon to Epitalon (Source: FDA substance identity record).

What the comparison does not show

The cited cell and animal experiments, including Epithalon's human-derived fibroblast culture, do not establish efficacy, safety or superiority of either peptide in people (Sources: Pinealon cell study, Pinealon rat study, EDR and KED mouse study, Epithalon fibroblast study).

The FDA record states that UNII availability does not imply regulatory review or approval (Source: FDA substance-record qualification).

Which material and lot records should a researcher open?

Use the listing for the intended compound: Pinealon research listing at Curo or Epithalon research listing at Curo. Each 10mg label describes a catalog pack amount.

Pinealon vs Epithalon FAQ

Are Pinealon and Epithalon interchangeable names?

No. Pinealon identifies Glu-Asp-Arg (EDR), while Epithalon identifies Ala-Glu-Asp-Gly (AEDG). Epitalon is an alias of Epithalon (Sources: Pinealon sequence source, Epitalon sequence and alias record).

Does the Epithalon human-cell paper count as a human trial?

No. The 2003 study measured telomerase and telomere changes in fibroblast culture; it did not test Epithalon in people (Source: 2003 Epithalon experimental-setting source).

Does a reference identifier certify a supplier's Pinealon or Epithalon lot?

No. PubChem CIDs 10273502 and 219042 describe the reference compounds and do not certify a supplier lot (Sources: Pinealon compound record, Epitalon compound record).
