    Livagen

    Bioregulator
    research only

    Livagen is a synthetic tetrapeptide composed of lysine, glutamic acid, aspartic acid, and alanine (Lys-Glu-Asp-Ala), developed by Professor Vladimir Khavinson as a bioregulator peptide targeting the liver. The liver is central to metabolic homeostasis, oxidative-stress pathways, protein synthesis, and bile production, and hepatocyte function declines progressively with age. Livagen is proposed to normalise hepatocyte gene expression by interacting with DNA to modulate chromatin condensation and transcriptional activity in aging liver tissue. One notable proposed mechanism is the promotion of chromatin decondensation in heterochromatin regions of aging hepatocytes, potentially reactivating silenced genes involved in liver regeneration and metabolic function.

    Vesugen

    Bioregulator
    research only

    Vesugen is a synthetic tripeptide composed of lysine, glutamic acid, and aspartic acid (Lys-Glu-Asp), developed by Professor Vladimir Khavinson as a bioregulator peptide targeting the vascular system. It is designed to support endothelial function and microcirculation by modulating gene expression in vascular endothelial cells. Age-related vascular decline, characterised by endothelial dysfunction, reduced nitric oxide bioavailability, and impaired microcirculation, is a major contributor to cardiovascular disease and organ dysfunction. Vesugen is proposed to interact with DNA in endothelial cells to normalise transcription of genes involved in vascular homeostasis, including those regulating nitric oxide synthesis, angiogenesis, and endothelial integrity.

    Cortagen

    Bioregulator
    research only

    Cortagen is a short synthetic bioregulator peptide developed by Professor Vladimir Khavinson and the St. Petersburg Institute of Bioregulation and Gerontology. It is designed to target the adrenal cortex, supporting the regulation of cortisol production and adrenal gland function. Bioregulator peptides are based on the concept that short peptide sequences derived from or mimicking endogenous tissue-specific peptides can restore gene expression patterns in aging or damaged tissues. Cortagen is proposed to normalise adrenal cortex function by interacting with DNA and modulating transcription of genes involved in androgen-pathway compoundsogenesis. While the bioregulator concept has theoretical appeal, the evidence base consists primarily of preclinical studies and observational reports from Russian clinical practice.

    research only

    PEG MGF

    Healing / Recovery
    phase 3

    Peginesatide is a synthetic PEGylated peptide-based erythropoiesis-stimulating agent (ESA) that activates the erythropoietin (EPO) receptor to stimulate red blood cell production. Marketed briefly as Omontys, it was designed as an alternative to recombinant EPO products for treating anemia in chronic kidney disease. Unlike traditional ESAs, peginesatide is a synthetic dimeric peptide with no structural homology to erythropoietin, developed to avoid anti-EPO antibody-mediated pure red cell aplasia. It received FDA approval in March 2012 but was voluntarily withdrawn in February 2013 following reports of serious hypersensitivity reactions including fatal anaphylaxis. Research interest continues in modified formulations and the synthetic peptide EPO agonist concept remains scientifically valid.

    Pinealon

    Cognitive / neurotrophic compounds
    research only

    Pinealon is a synthetic tripeptide composed of glutamic acid, aspartic acid, and arginine (Glu-Asp-Arg, or EDR). Developed by Professor Vladimir Khavinson at the St. Petersburg Institute of Bioregulation and Gerontology, Pinealon is designed as a bioregulator peptide targeting the pineal gland. The pineal gland plays a central role in circadian rhythm regulation through endocrine signalling. Pinealon is proposed to normalise pineal gland function by modulating gene expression related to pineal hormone production, potentially supporting sleep quality, circadian rhythm integrity, and neuroprotection. As a short peptide, it is theorised to penetrate cells and interact with DNA to restore age-related decline in pineal function. Evidence remains limited to preclinical studies.

    Vilon

    Bioregulator
    research only

    Vilon is a synthetic dipeptide consisting of lysine and glutamic acid (Lys-Glu), developed by Professor Vladimir Khavinson as a bioregulator peptide targeting the thymus gland. The thymus is the primary organ responsible for T-cell maturation and plays a critical role in adaptive immune function. With aging, the thymus undergoes involution, leading to progressive immunosenescence characterised by declining T-cell diversity and impaired immune surveillance. Vilon is proposed to modulate thymic gene expression, potentially restoring aspects of thymic function and supporting T-cell differentiation. As a dipeptide bioregulator, it represents the smallest functional unit in the Khavinson bioregulation framework, theorised to interact with DNA to normalise immune gene expression.
