Pinealon / EDR: Comparing Cell-Model and Transporter-Docking Source Records

Research use only. This article discusses literature and documentation review. It does not provide human or veterinary use, dosing, administration, safety, or outcome guidance.

Use Pinealon and EDR as terms to compare, not as proof of identity

PubChem indexes Pinealon as an EDR compound record (CID 10273502). That makes EDR a controlled search term, but it does not identify a catalogue batch or prove that every paper using EDR tested the same preparation. The useful question is therefore not whether a source contains the letters EDR, but what material, system, and method the authors actually report.

Source record 1: EDR in a cell-transdifferentiation workflow

Sakhenberg et al. (2025; PMID 41020860) included EDR alongside KED and AEDG in fetal mesenchymal stem cells undergoing transdifferentiation into induced cortical neurons. The workflow combined microRNAs, transcription factors, and small molecules, then assessed selected cell-cycle and senescence-related markers. EDR was one element in a multi-peptide, defined in vitro design; the paper does not isolate a received Pinealon batch.

Source record 2: EDR in a computational transporter screen

Khavinson et al. (2023; PMID 36979488) placed EDR among 26 ultrashort peptides in molecular-modelling and computer-assisted docking work against LAT1, LAT2, and PEPT1 binding sites. The study compares calculated ligand interactions across a large peptide set. It is a computational transport-feasibility record, not a cell-uptake assay, analytical measurement, or product-characterization study.

What the comparison changes

The first source uses EDR inside a multi-peptide cell workflow; the second uses EDR inside an in silico transporter comparison. They are complementary only at the level of research questions, not as interchangeable proof. Neither source establishes the identity, purity, stability, transport, or result of the material linked above.

Documentation decision

For a received item, retain the label, lot identifier, receipt date, and supplied COA or SDS. Put each source in a separate literature note with its terminology, system, method, endpoint, and limitation. This preserves an auditable route from EDR search terms to the actual scope of each paper.
