Biography & Research Overview
Professor Vladimir Khavinson (V. Kh. Khavinson) is a Russian scientist and academician of the Russian Academy of Sciences, widely regarded as the pioneer of peptide bioregulator research. Based at the St. Petersburg Institute of Bioregulation and Gerontology (North-Western Branch of the Russian Academy of Medical Sciences), Khavinson has spent over 50 years researching short peptide compounds and their effects on aging, gene expression, and longevity. His work centers on the concept that short peptides (2-4 amino acids) can act as epigenetic regulators, binding to specific DNA sequences and modulating gene expression. He developed numerous peptide bioregulators including Epitalon (Epithalon), Thymalin, Vilon, and Cortexin, which have been studied in Russian clinical settings for decades. A significant portion of Khavinson's research was originally published in Russian journals (such as Byulleten' Eksperimental'noi Biologii i Meditsiny and Uspekhi Gerontologii). Many of these papers have since been translated to English and indexed in PubMed. His English-language reviews in Neuro Endocrinology Letters and Advances in Gerontology are publicly available. Note: The Alzheimer's Drug Discovery Foundation's Cognitive Vitality report notes that most epithalamin/epithalon studies were conducted by Khavinson's group without independent replication, and approximately half of the ~110 published articles are in Russian. We present this research for informational purposes and encourage readers to review the original publications.
Key Concepts in Peptide Bioregulation
Short Peptides as Epigenetic Regulators
Khavinson proposes that short peptides (2-4 amino acids) bind to specific DNA sequences and modulate gene expression, effectively resetting genes to a healthier state.
Tissue-Specific Peptide Design
Based on amino acid compositions of peptide extracts from different organs, Khavinson developed synthetic short peptides with tissue-specific activity (pineal gland, thymus, brain cortex, retina, etc.).
Publications & English Summaries
Many of Khavinson's papers were originally published in Russian. Below we provide English summaries with links to the original publications or their English translations where available. Papers marked as "Translated" were originally in Russian — we summarize the English translations or provide our own summaries of the Russian original.
Khavinson VKh, Bondarev IE, Butyugov AA · Bulletin of Experimental Biology and Medicine · 2003
Published in English. Epithalon (Ala-Glu-Asp-Gly) activated telomerase in human fibroblasts, inducing telomere elongation. This is the foundational study linking short peptides to telomere biology and cellular aging.
Khavinson VKh · Neuro Endocrinology Letters (Suppl 3) · 2002
144-page English-language supplement. Comprehensive review of peptide bioregulator technology. Covers Epithalamin, Thymalin, and the design principles for synthetic short peptides. Describes tissue-specific activity and geroprotective effects across multiple animal models and human clinical trials.
Original: Геропротекторный эффект тималина и эпиталамина
Khavinson VKh, Morozov VG · Advances in Gerontology (Uspekhi Gerontologii) · 2002
Originally published in Russian. 6-8 year clinical study in 266 elderly patients at the St. Petersburg Institute of Bioregulation and Gerontology. Thymalin and Epithalamin normalized cardiovascular, endocrine, immune, and nervous system function. Combined annual treatment over 6 years reduced mortality 4.1-fold compared to control. This is one of the longest-running peptide bioregulator clinical trials on record.
Khavinson VKh, Izmaylov DM · Mechanisms of Ageing and Development · 2000
Published in English. Epitalon increased Drosophila lifespan by 11-16% at very low concentrations (0.001-0.0001%). Demonstrated antioxidant properties. This study established epitalon as a geroprotector using a well-controlled invertebrate aging model with rigorous statistical methods.
Original: Короткие пептиды регулируют экспрессию генов
Khavinson VKh, Lin'kova NS, Tarnovskaya SI · Bulletin of Experimental Biology and Medicine · 2016
Originally published in Russian, this English translation is available via khavinson.info. Used molecular docking to model DNA-peptide interactions for 19 short peptides. Found that tetrapeptides (KEDA, KEDW, AEDR, EDR) demonstrate strong DNA interactions. Dipeptides KE and EDP bind to specific DNA sequences (agat), forming hydrogen bonds with adenine and the phosphate backbone. This research forms the theoretical basis for how short peptides regulate gene expression.

Khavinson VKh, Kuznik BI, Ryzhak GA · Advances in Gerontology · 2014· CC-BY-NC
English-language review of clinical trials of seven peptide bioregulators (Timalin, Thymogen, Vilon, Epithalamin, Prostatilen, Cortexin, Retinalamin). Analyzes their geroprotective effects across all age groups. Reviews disease prevention and health maintenance data from long-term Russian clinical studies.

Khavinson VKh, Morozov VG · Bulletin of Experimental Biology and Medicine · 2003
Originally published in Russian. English summary available. Long-term clinical assessment of Thymalin and Epithalamin in 266 elderly persons over 6-8 years. Treatment normalized cardiovascular, endocrine, immune, and nervous system function. Reduced incidence of ischemic heart disease, hypertension, osteoarthrosis, and osteoporosis. Combined treatment reduced mortality 4.1-fold over 6 years. This is the landmark study on peptide bioregulators and human longevity.

Khavinson VKh, Linkova NS, Ashapkin VV, et al. · Advances in Gerontology · 2023
Originally published in Russian. KE peptide (Lys-Glu, also known as Vilon) increased SIRT1 gene expression 6x and protein synthesis 8.2x in young mesenchymal stem cells. Reduced PARP1 and PARP2 expression during aging. Molecular modeling showed KE peptide interacts with specific DNA sequences in SIRT1, PARP1, and PARP2 gene promoters. This is recent work (2023) demonstrating the epigenetic mechanism of peptide bioregulators.

Note on Independent Replication
The Alzheimer's Drug Discovery Foundation's Cognitive Vitality report notes that most epithalamin/epithalon studies were conducted by Khavinson's group in Russia without independent confirmation, and approximately half of the ~110 published articles are in Russian. We present this research for informational purposes and encourage readers to review the original publications and seek independently replicated studies where available.
