Chonluten is a synthetic tripeptide printed in opened Khavinson-group papers as Glu-Asp-Gly (EDG), positioned as a short peptide bioregulator associated with respiratory-tissue / bronchial-epithelium research. English-language independently replicated evidence is sparse. It is not Bronchogen, not Epitalon, and not an FDA-approved drug on any opened registry. Research use only. Not medical advice. Not for human use.
Educational information only. This page describes a short peptide bioregulator sold as a laboratory research material. It is not medical advice. Simple Research Peptides (SRP) materials are for laboratory research only and are not for human or veterinary use, consumption, administration, diagnosis, treatment, or therapeutic application. Sequence Glu-Asp-Gly / EDG is taken from opened papers, not from the SRP product page. No human dosing, reconstitution, or administration protocol appears on this page.
SRP product and index pages do not print a sequence, CAS, UNII, molecular formula, or a public COA. The sequence below is taken only from opened primary papers that print the trade name Chonluten next to the three-letter sequence. The CAS / formula / CID row is the opened PubChem record for glutamyl-aspartyl-glycine (Glu-Asp-Gly). PubChem does not list the trade name Chonluten as a synonym.
One-sentence identity: Chonluten is a synthetic tripeptide printed in opened Khavinson-group papers as Glu-Asp-Gly (EDG), positioned as a short peptide bioregulator associated with respiratory-tissue / bronchial-epithelium research. English-language independently replicated evidence is limited. It is not Bronchogen, not Epitalon, and not an FDA-approved drug on any opened registry.

What this is chemically, from opened pages. Three independent opened Khavinson-group papers print Chonluten as the unmodified tripeptide Glu-Asp-Gly (EDG). Avolio et al. 2022 additionally state that some of the peptides, including Chonluten, were synthetized on the basis of the information of their natural counterparts, and that Chonluten is from respiratory lung / derived from bronchial epithelial cells. PubChem CID 194641 is the matching L-Glu–L-Asp–Gly structure (CAS 75007-24-8; synonym T-34 tripeptide). That CID does not print the marketplace name Chonluten.
What this is not, chemically.
Not printed on SRP pages and therefore not claimed as SRP-verified: sequence, CAS, UNII, formula, T-34 code, or purity numbers. The product page does not print a public COA.
Honluten. Europe PMC REST returned 0 records for honluten. No opened primary paper printed that spelling. Vendor/blog pages that treat Honluten as a synonym were not used as identity sources.
Chonluten (this page) is the tripeptide Glu-Asp-Gly (EDG) on the opened Avolio 2022, Khavinson 2020, and Khavinson 2022 pages. It is one name inside the Khavinson / cytomedin-style short-peptide bioregulator catalog. That catalog is a research-network taxonomy, not a receptor-class assignment.
Bronchogen is a different molecule. Do not cite Bronchogen papers as Chonluten evidence. Opened pages print Bronchogen as a tetrapeptide. The printed one-letter order is not even internally consistent: some papers print ADEL (Ala-Asp-Glu-Leu) and others print AEDL (Ala-Glu-Asp-Leu). Those are not the same four residues in the same order. This page records both printings and does not collapse them.
| Opened page | What it printed for bronchogen / the lung tetrapeptide | Why it is not Chonluten |
|---|---|---|
| Khavinson et al. 2020 PMID 32987757 |
AEDL tetrapeptide (Bronchogen) vs EDG tripeptide (Chonluten) | Explicitly a different sequence and a different trade name. |
| Khavinson et al. 2022, Table 2 PMID 35887081 |
Bronchogen (AEDL), ICM-score −17.26, labeled Bronchoprotector; Chonluten (EDG), ICM-score −30.30, labeled Gastroprotector / Stress protector | Same table, two rows, two sequences. |
| Khavinson et al. 2014, Lung PMID 25015171 — NOT Chonluten efficacy |
Tetrapeptide Ala-Asp-Glu-Leu (ADEL) in human embryonic bronchial-epithelium cultures; gene/protein panel (Ki67, Mcl-1, p53, NKX2-1, MUC4, MUC5AC, SFTPA1, etc.) | Sequence printed is ADEL, not EDG. Abstract never names Chonluten. |
| Monaselidze et al. 2011 PMID 21240358 — NOT Chonluten efficacy |
peptide bronchogen (Ala-Asp-Glu-Leu) as a DNA-stabilizing ligand | ADEL tetrapeptide, not EDG. |
| Khavinson et al. 2012 PMID 22808515 — NOT Chonluten efficacy |
bronchogen (Ala-Glu-Asp-Leu) stimulated CXCL12 / Hoxa3 in aging bronchial-cell cultures | AEDL tetrapeptide, not EDG. |
| Kuzubova et al. 2015 PMID 26468022 — NOT Chonluten efficacy |
tetrapeptide Bronchogen for 1 month in a rat NO2 COPD model | Tetrapeptide; not named Chonluten or EDG. |
PMID 25015171 and PMID 21240358 print Ala-Asp-Glu-Leu (ADEL). PMID 22808515 and PMID 32987757 / PMID 35887081 print Ala-Glu-Asp-Leu (AEDL). Those are not the same four residues in the same order. This page records both printings and does not collapse them. Do not merge Bronchogen into Chonluten.
Epitalon (AEDG) is printed in Avolio 2022 Methods as Ala-Glu-Asp-Gly, from pineal gland. Four residues, different N-terminus. Do not treat Epitalon telomerase / melatonin papers as Chonluten evidence.
These appear on the opened 2022 transport table as KEDA, EDL, and KED respectively, with different tissue labels (hepato-/nephro-protector; vasoprotector). They are catalog siblings, not synonyms of Chonluten.
PubChem lists T-34 tripeptide as a synonym of Glu-Asp-Gly (CID 194641). Khavinson et al. 2012 (PMID 22803148) is an opened abstract-only paper about geroprotective peptide T-34 in a gastric-ulcer setting. That opened abstract does not print the name Chonluten, the letters EDG, or the sequence Glu-Asp-Gly. The 2020 COVID review cites this paper when it attributes c-Fos / HSP70 / SOD / COX-2 / TNF-α regulation to EDG. Because the 2012 full text was subscription-walled and the opened abstract does not print those gene names or the Chonluten trade name, this page does not treat PMID 22803148 as a confirmed Chonluten primary experiment. Label: NOT Chonluten efficacy.
Opened pages support a working model from one research network, not a locked receptor identity. None of this is a treatment claim, and none of it identifies which salt or assay is in an SRP vial. Observed means a measurement in an opened paper that names Chonluten. Proposed means docking or review-level language. Class / review means related-family or review text. Not shown means the opened papers did not establish it.
Avolio et al. 2022 call Chonluten a synthetic bronchial bio-regulator whose principal biological targets are the respiratory system, and they state that Khavinson peptides were initially isolated from animal tissues and found to be organ specific. IUPHAR returned no ligand. No opened paper printed a single defined cell-surface receptor for EDG. (PMID 35408963.)
Avolio et al. 2022 incubated THP-1 cells with 100 ng/mL of each peptide overnight, ± 100 ng/mL LPS. Findings specific to Chonluten (P5) on that opened full text: a moderate but consistent apoptotic profile on FACS, doubling the value in relation to other peptides (Supplementary Data; the main text does not print a numeric apoptotic percentage); a slight release of TNF from otherwise unstimulated monocytes, which the authors interpret as a possible TNF-tolerance / anergy signal — not as a proinflammatory disease finding; together with Epitalon and Vilon, Chonluten increased STAT1 phosphorylation in PMA-differentiated THP-1 macrophages, functioning possibly via a receptor-independent mechanism, with no effect on IFN-α production. (PMID 35408963.)
Shared with the other four peptides, not unique to Chonluten: increased ERK1/2 phosphorylation (all except Vilon); reduced LPS-stimulated TNF-α, IL-6, and (to varying degrees) IL-17; reduced adhesion of peptide-pretreated THP-1 cells to LPS-activated HUVECs. This is a human leukemia monocytic cell line. It is not bronchial epithelium, not an animal lung-injury model, and not a human trial. (PMID 35408963.)
Khavinson et al. 2022 (review + ICM docking) list Chonluten (EDG) among ultrashort peptides with a LAT1 docking ICM-score of −30.30, among the more favorable scores in that table (Vesilut/ED −34.32; Pinealon/EDR −30.29; Bronchogen/AEDL only −17.26). The paper’s claim is that di- and tripeptides can be LAT1/POT substrates depending on structure. It does not measure Chonluten flux in a cell, and the same table labels EDG a gastroprotector / stress protector, not a bronchoprotector. (PMID 35887081.)
The 2020 COVID review states that EDG’s stress-protective effect is associated with its ability to regulate the expression of the c-Fos gene, the heat shock protein gene HSP70, the genes encoding the enzymes of the antioxidant system, SOD, COX-2 and the tumor necrosis factor gene TNF-α, citing PMID 22803148. That citation’s opened abstract is a gastric-ulcer T-34 paper and does not print those gene names. The opened 2014 Lung gene-expression paper (PMID 25015171) is ADEL, not EDG. Do not transfer the ADEL bronchial gene panel (NKX2-1, FOXA1/2, MUC4, MUC5AC, SFTPA1) onto Chonluten. (PMID 32987757.) 2020 review oral COPD / COVID language = unverified review claims.
The 2021 systematic review (PMID 34834147) discusses 2–7 residue peptides penetrating nuclei and contacting DNA/histones. Its opened full text does not mention Chonluten or Glu-Asp-Gly. It is background for the bioregulator hypothesis, not a Chonluten mechanism paper. Label: NOT Chonluten efficacy.
Human numbers below, where a review mentions them, are unverified review assertions. They are not instructions for using SRP research vials, and they are not claims that research-grade material works in people.
English-language independently replicated evidence is limited / sparse. Almost every opened record is from the Saint Petersburg Institute of Bioregulation and Gerontology network or a collaboration that includes Khavinson as a co-author. Europe PMC search for chonluten returned 3 hits. Only one opened primary experiment (Avolio 2022, THP-1 cells) names and tests Chonluten. No trial registration. No opened human RCT.
Avolio et al., Int J Mol Sci 2022. PMID 35408963. DOI 10.3390/ijms23073607. PMC8999041. Human THP-1 monocytes ± PMA to macrophages; 100 ng/mL peptide overnight ± 100 ng/mL LPS; HUVEC adhesion. Methods print Chonluten = Glu-Asp-Gly. This is the only opened primary experiment that names and tests Chonluten. Not lung tissue. Not an animal model. Not a human trial.
Khavinson et al. 2020 COVID review (PMID 32987757) prints EDG tripeptide (Chonluten) and asserts oral EDG use in bronchopulmonary pathology. Those oral COPD / COVID sentences are unverified review claims. Khavinson et al. 2022 transport review + docking (PMID 35887081) prints Chonluten (EDG) with LAT1 ICM-score −30.30. Neither paper is a new trial.

Chonluten = Bronchogen is false. Chonluten = Epitalon is false. Honluten is the same thing is not printed on any opened primary paper. FDA approved / treats COPD / asthma / COVID is contradicted by openFDA empty results, ClinicalTrials.gov zero studies, and the fact that the COVID paper is a review of prospects. Do not use those claims.

Peptides Regulating Proliferative Activity and Inflammatory Pathways in the Monocyte/Macrophage THP-1 Cell Line. Methods 4.1 print P5 as Chonluten (tripeptide Glu-Asp-Gly, from respiratory lung). Chonluten-specific findings on the opened full text: moderate but consistent apoptotic profile on FACS; slight unstimulated TNF; STAT1 phosphorylation with Epitalon and Vilon, possibly via a receptor-independent mechanism, no effect on IFN-α. Shared findings: ERK1/2 (except Vilon); reduced LPS-stimulated TNF-α, IL-6, and (to varying degrees) IL-17; reduced THP-1 adhesion to LPS-activated HUVECs.

Prints EDG tripeptide (Chonluten) and AEDL tetrapeptide (Bronchogen). Asserts that oral EDG is effective for the treatment of bronchopulmonary pathology (chronic obstructive pulmonary disease, chronic bronchitis with an asthmatic component); that oral EDG increased a physical performance index and normalization of the organism functional state when exposed to low oxygen partial pressure; and that EDG enhanced the effectiveness of standard therapy in patients with chronic bronchitis with an asthmatic component. Attributes c-Fos / HSP70 / SOD / COX-2 / TNF-α regulation to EDG, citing PMID 22803148. Proposes EDG/AEDL as possible COVID-19 adjuncts. | No methods, n, endpoints, or trial registration.

The 2020 review’s sentences about COPD, chronic bronchitis, hypoxia, and standard therapy are not backed by an opened protocol, results table, or PubMed-indexed RCT that this pass could retrieve under those names. Those sentences remain unverified review claims.
This page does not provide reconstitution, administration, or dosing instructions. Historical review language about oral EDG is not a protocol for an SRP research vial.
Bottom line from opened sources: Chonluten is a research-marketplace / Khavinson-catalog name for a tripeptide. It is not FDA-approved as a US drug on any opened FDA or NCATS page. An SRP research vial is not a licensed medicine. Research use only. Not medical advice. Not for human use.
| Claim | What an opened page actually said | What we did not open / confirm |
|---|---|---|
| US FDA marketing approval | openFDA Drugs@FDA and label APIs: No matches found for chonluten. NCATS Inxight HTML/API: no substance named chonluten. IUPHAR: no ligand. | A Drugs@FDA NDA/BLA page (none found). Do not invent an NDA, ANDA, or BLA number. |
| UNII / GSRS | PubChem CID 194641 printed no UNII. FDA UNII search API path returned 404. NCATS name search empty. | A UNII for Glu-Asp-Gly. Absence of a found UNII is not proof that SRS will never assign one. |
| INN / USAN | None on opened WHO/NCATS/IUPHAR pages. | A WHO INN list entry (not found, not opened). |
| Marketed dietary-supplement use in Russia / CIS | Not independently confirmed on an opened regulator page. The 2020 review discusses oral EDG as if it were used clinically; that is author language, not an FDA/EMA authorization. | A country-by-country marketing-authorization table. |
The following are not established on opened pages. Keep this list visible. Sparse evidence is not mixed evidence.
No opened RCT, no trial registration, no opened primary clinical paper that names Chonluten. Review sentences about COPD, asthmatic-component bronchitis, hypoxia, and standard therapy remain unverified.
Not FDA-approved for any indication on opened FDA, NCATS, or openFDA pages as of 16 August 2026.
The THP-1 findings, or any lung-specific EDG experiment, have not been independently replicated outside the Khavinson network in opened English-language papers.
No opened paper identified a defined cell-surface receptor for Chonluten / EDG. No opened pharmacokinetics program.
Those are different sequences on the opened pages (ADEL / tetrapeptide Bronchogen vs EDG).
The CID is Glu-Asp-Gly / T-34 tripeptide. The trade name is not on that record. Chonluten is not a PubChem synonym.
The opened abstract does not print that link. Label: NOT Chonluten efficacy.
SRP pages do not print sequence, CAS, salt, or a public COA.
Out of scope for this facts page. No human dosing protocol appears here.
No opened toxicology program, no opened SAE table.
Category names are store taxonomy, not clinical indications. Keep the sparse/limited evidence wording. Do not invent a sequence as if SRP verified it.
| Claim type | What opened pages actually support | Flag |

Chonluten is a laboratory research peptide. It is not an FDA-approved drug for human use. This page is educational. It does not provide dosing, reconstitution, administration, or any human-use instructions.
Simple Research Peptides (SRP) materials are for laboratory research only and are not for human or veterinary use, consumption, administration, diagnosis, treatment, or therapeutic application.
Laboratory identity is the first practical issue. Opened papers print Chonluten as Glu-Asp-Gly (EDG). PubChem CID 194641 is glutamyl-aspartyl-glycine / T-34 tripeptide, CAS 75007-24-8. Chonluten is not a PubChem synonym. SRP product pages do not print sequence, CAS, UNII, or formula. A method written for Bronchogen (ADEL or AEDL), Epitalon (AEDG), or any other bioregulator is not automatically valid for this tripeptide.
Biological inference has the same problem. Avolio 2022 is one THP-1 cell paper. Two reviews name EDG. 2020 review oral COPD / COVID sentences are unverified review claims. Human trials: NONE. Independently sourced research peptides are not established as equivalent to the 100 ng/mL culture reagent in Avolio 2022. Confirm sequence and assay before treating a vial as the literature compound.
A Khavinson-catalog synthetic tripeptide printed as Glu-Asp-Gly (EDG) in the opened papers above, sold as a 20 mg research vial. Research-use-only. Evidence is sparse.
Yes, on three opened papers that print the trade name next to Glu-Asp-Gly / EDG (Avolio 2022 Methods, PMID 35408963; Khavinson 2020, PMID 32987757; Khavinson 2022 Table 2, PMID 35887081). SRP’s own page does not print it. Confirm the vial by sequence and assay.
PubChem lists T-34 tripeptide as a synonym of Glu-Asp-Gly (CID 194641). The opened 2012 T-34 abstract (PMID 22803148) does not print Chonluten. Treat T-34 as a possible laboratory code for the same tripeptide, not as a second confirmed clinical article. Label: NOT Chonluten efficacy.
Bronchogen is a tetrapeptide (printed as ADEL or AEDL, depending on the paper). Chonluten is a tripeptide (EDG). Several opened lung-remodeling and bronchial-gene papers test Bronchogen / ADEL, not Chonluten. The ADEL vs AEDL inconsistency is recorded and is not collapsed. Do not merge the two molecules.
Different sequences on the opened Avolio Methods and 2022 transport table: Epitalon AEDG; Livagen KEDA; Ovagen EDL; Vesugen KED. Shared bioregulator branding is not shared pharmacology.
No opened trial. ClinicalTrials.gov returned zero studies. A 2020 review from the same institute asserts oral EDG use in bronchopulmonary disease; those sentences are not an opened RCT. Human trials: NONE. Do not invent a trial registration number.
Not on any opened FDA, NCATS, or openFDA page as of 16 August 2026. Not FDA-approved.
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. Not medical advice. Not for human use.
Thin. Sparse. One opened primary cell-culture paper names and tests Chonluten (Avolio 2022 THP-1). Two opened reviews name it. The rest of the respiratory-looking literature that this pass opened is Bronchogen / ADEL. Independent English-language replication, PK, and controlled human data are not established.
No. There is no human dosing, reconstitution, or administration protocol on this page. Research use only.
Sources actually opened for this draft. PMIDs that name Chonluten / EDG: 35408963, 32987757, 35887081. Distinction-only PMIDs (label as NOT Chonluten efficacy): 22803148, 25015171, 21240358, 22808515, 26468022, 30199201, 34834147. No trial registration number is listed because ClinicalTrials.gov returned 0 studies. Do not invent one.

Educational information only. Chonluten is a synthetic tripeptide printed as Glu-Asp-Gly (EDG) in opened papers. It is not Bronchogen, not Epitalon, and not an FDA-approved drug. Evidence is sparse: one primary cell paper (Avolio 2022 THP-1). Human trials: NONE. 2020 review oral COPD / COVID = unverified review claims. PubChem CID 194641 / CAS 75007-24-8 is Glu-Asp-Gly / T-34; Chonluten is not a PubChem synonym. Laboratory research use only; not for human or animal use. Not medical advice. Not for human use. No human dosing protocol. Last source review: 16 August 2026 (America/Indianapolis). Locked draft converted to HTML the same day. For laboratory research only. Not for human or veterinary use.
