[Adaptive response in vivo: reasons for increase of radioresistance in CFU-S].

Semenets. T N TN; Semina. O V OV; Poverennyĭ. A M AM; Deĭgin. V I VI; Korotkov. A M AM;...

In mice, a tiny amount of radiation makes blood‑forming stem cells tougher, and giving a synthetic RNA (PolyI‑PolyC) before a big radiation dose helps them grow even more. Adding the peptide thymogen boosts stem‑cell colonies equally in both pre‑conditioned and normal mice, suggesting it can enhance recovery after radiation stress.

[Inhibiting effect of thymogen on the development of tumors of the esophagus and forestomach induced by N-nitrososarcosine ethyl ester in rats].

Bespalov. V G VG; Troian. D N DN; Petrov. A S AS; Morozov. V G VG; Khavinson. V Kh VKh

In a rat study, the synthetic peptide thymogen slightly lowered the number and size of esophagus and stomach tumors caused by a chemical carcinogen, cutting tumor occurrence by about 12% and reducing tumor count per animal by roughly 40%. The effect was modest and seen only in this specific animal cancer model.

Reparative and Antioxidant Effects of New Analogues of Immunomodulator Thymogen in Experimental Model of Liver Damage.

Chulanova. A A AA; Smakhtin. M Yu MY; Bobyntsev. I I II; Mishina. E S ES; Artyushkova. E B EB; Smakh...

In a rat study, the immune‑boosting peptide Thymogen and new versions of it (with a D‑alanine amino acid added to the ends) helped protect the liver from damage caused by a toxic chemical. The modified peptides, especially when D‑alanine was attached to the C‑end, reduced oxidative stress and promoted liver cell repair more than regular Thymogen.

[Age features of bioregulatory therapy of dental diseases.].

Pinelis. I S IS; Pinelis. Y I YI; Kuznik. B I BI; Iordanishvili. A K AK; Vasiliev. M A MA

The paper reviews how peptide bioregulators such as thymalin, thymogen, and others may help treat dental and maxillofacial problems, especially in older people. It focuses on their immune‑modulating and protective effects rather than giving new experimental data.

[Decision on the immunomodulating therapy in unspecific osteomyelitis of the spine].

Vishnevskiĭ. A A AA; Orlov. A B AB; Tikhodeev. S A SA

A small clinical study of 54 patients with spinal bone infection found that adding immune‑boosting drugs like thymogen (a thymus‑derived peptide) helped when the patients had weak T‑cell immunity. The authors suggest that checking which part of the immune system is impaired and then using the right peptide or cytokine could improve outcomes.

Enhancement of oral drug absorption-effect of lipid conjugation on the enzymatic stability and intestinal permeability of l-Glu-l-Trp-NH(2).

Bergeon. Julie A JA; Toth. Istvan I

Scientists attached fatty‑like chains to a tiny protein fragment (IM862) to see if it could survive the gut and get into the bloodstream when taken as a pill. In lab tests, some of the modified versions were tougher against digestive enzymes and crossed a cell layer that mimics the intestine better than the original, hinting that this trick might make oral dosing possible.

[The effect of thymogen on the heart in ischemia and reperfusion].

Filippova. O V OV; Reznikov. K M KM; Alabovskił. V V VV; Khamburov. V V VV; Vinokurov. A A AA

In a lab test using isolated hearts, the peptide thymogen helped protect the heart from damage caused by cutting off and then restoring blood flow. It worked better than two other drugs (dalargin and verapamil) and did so without using the usual opioid or calcium‑channel pathways.

[Application of immunomodulators for correction of changes in the immune system in conditions of experimental hypothyroidism].

Zamotaieva. H A HA; Sydorenko. D S DS; Stepura. N M NM; Zakharchenko. T F TF; Hoĭdash. M M MM;...

In mice that had their thyroid removed, the researchers found that the immune system got weaker (lower thymus activity, less IL‑2, weaker killer cells, and more immune complexes). Giving the hormone thyroxine plus the immune‑boosting drugs thymogen or polyoxydonium helped, but only partially. When the thyroid hormone levels were first corrected, adding thymogen or polyoxydonium gave a bigger boost and helped the immune system recover more fully.

[The effect of the synthetic immunomodulator thymogen on radiation-induced carcinogenesis in rats].

Anisimov. V N VN; Miretskiĭ. G I GI; Morozov. V G VG; Pavel'eva. I A IA; Khavinson. V Kh VKh

In a rat study, a synthetic peptide called thymogen was given once a month for five days. The rats that got thymogen had fewer cancers caused by radioactive chemicals and lived longer with fewer age‑related tumors. The peptide also seemed to protect against spontaneous cancers when given by itself.

[Influence of peptides from pineal gland on thymus function at aging].

Lin'kova. N S NS; Poliakova. V O VO; Trofimov. A V AV; Sevost'ianova. N N NN; Kvetnoĭ. I M IM

The review compares peptides from the pineal gland (like epithalamin/epitalon) with those from the thymus (like thymalin/thymogen) and finds that pineal peptides are better at protecting the thymus as we age. Thymogen, a thymus‑derived peptide, shows weaker anti‑aging effects on the pineal gland.

[Possibilities of the application of antioxidants and antihypoxants in a complex therapy of obsessive conditions in different mental disorders].

Podsevatkin. V G VG; Kiriukhina. S V SV

In a study of 84 people with obsessive‑compulsive disorder or tic disorders, adding the peptide thymogen (along with mexidol and hyperbaric oxygen) helped improve symptoms more than standard drugs like antipsychotics and benzodiazepines. The researchers also noted immune system and hormone imbalances in these patients.

Natural killer cell cytolytic activity is necessary for in vivo antitumor activity of the dipeptide L-glutamyl-L-tryptophan.

Smith. D Lynne DL; Cai. Jie J; Zhu. SuTao S; Wei. Wen W; Fukumoto. Jon J; Sharma. Sanjai S; Masood....

A tiny protein fragment called L‑glutamyl‑L‑tryptophan (L‑glu‑L‑trp) was found in mouse thymus tissue and can slow tumor growth in mice, but only when natural killer (NK) immune cells are working properly. It doesn’t kill cancer cells directly; instead it helps NK cells kill them, and this effect needs a protein called perforin and partly depends on another immune signal, IL‑12. The peptide works even without IFN‑γ, another immune molecule.

[Radiation protective effect of low molecular weight thymus preparations].

Baraboĭ. V A VA; Ialkut. S I SI; Savtsova. Z D ZD; Zinchenko. V A VA; Zhukova. V M VM; Zaritsk...

The study found that low‑molecular‑weight thymus extracts such as thymogen can lessen the harmful effects of radiation on blood formation, the gut, and the immune system. The authors suggest that these extracts work by supporting the body’s natural repair pathways after radiation exposure.

[Thymogen in the complex treatment of inflammatory diseases of the female genital system].

Tsvelev. Iu V IuV; Khavinson. V Kh VKh; Diachuk. A V AV; Gur'ev. A V AV; Seryĭ. S V SV

The study looked at 46 women with serious uterine infections and gave them a drug called Thymogen along with standard treatment. After the therapy, their immune cell numbers and activity improved, and no side effects were reported. The authors say Thymogen helped the patients get better, but the report doesn’t give details on dose, timing, or how it compares to a placebo.

Novel platform for the preparation of synthetic orally active peptidomimetics with hemoregulating activity. II. Hemosuppressor activity of 2,5-diketopiperazine-based cyclopeptides.

Deigin. Vladislav V; Ksenofontova. Olga O; Yatskin. Oleg O; Goryacheva. Alexandra A; Ignatova. Anast...

Scientists created new oral versions of a tiny protein fragment (a dipeptide) that can calm down the bone‑marrow blood‑forming system. The original Glu‑Trp peptide boosts immunity (the drug Thymogen), but flipping both amino acids to their mirror‑image (D‑Glu‑D‑Trp) flips the effect, suppressing blood‑cell growth. The study shows this flip works even when the peptide is built into a ring‑shaped molecule that can be taken by mouth.

[Interaction of the synthetic immunomodulatory dipeptide bestim with murine macrophages and thymocytes].

Kolobov. A A AA; Kolodkin. N I NI; Zolotarev. Iu A IuA; Tathill. C C; Navolotskaia. E V EV

This mouse study shows that the synthetic peptide thymogen (bestim) tightly binds to immune cells and can lower an enzyme called adenylate cyclase, but it only tested cells in a dish and gave no human data or dosing guidance, so it isn’t ready for practical use by biohackers.
