Vesugen

aka Lys-Glu-Asp

Immune Modulator

Mechanism

Vesugen is a synthetic tripeptide, Lys-Glu-Asp (KED), from the Khavinson short-peptide 'bioregulator' series, positioned as a short-peptide analog of a bovine vascular-tissue polypeptide complex and claimed to be vasoprotective. Marketed on the Russian/Ukrainian grey market; not FDA-approved in the US; research-use only.

Short Peptides Protect Fibroblast-Derived Induced Neurons from Age-Related Changes
Kraskovskaya N, Linkova N, Sakhenberg E, Krieger D, Polyakova V, Medvedev D, Krasichkov A, Khotin M, Ryzhak G. · International journal of molecular sciences (2024) ·

Neurons become more vulnerable to stress factors with age, which leads to increased oxidative DNA damage, decreased activity of mitochondria and lysosomes, increased levels of p16, decreased LaminB1 proteins, and the depletion of the dendritic tree.

Transport of Biologically Active Ultrashort Peptides Using POT and LAT Carriers
Khavinson V, Linkova N, Kozhevnikova E, Dyatlova A, Petukhov M. · International journal of molecular sciences (2022) · review

Ultrashort peptides (USPs), consisting of 2-7 amino-acid residues, are a group of signaling molecules that regulate gene expression and protein synthesis under normal conditions in various diseases and ageing. USPs serve as a basis for the development of drugs with a targeted mechanism of action.

Neuroprotective Effects of Tripeptides-Epigenetic Regulators in Mouse Model of Alzheimer's Disease
Khavinson V, Ilina A, Kraskovskaya N, Linkova N, Kolchina N, Mironova E, Erofeev A, Petukhov M. · Pharmaceuticals (Basel, Switzerland) (2021) · animal

KED and EDR peptides prevent dendritic spines loss in amyloid synaptotoxicity in in vitro model of Alzheimer's disease (AD). The objective of this paper was to study epigenetic mechanisms of EDR and KED peptides' neuroprotective effects on neuroplasticity and dendritic spine morphology in an AD mouse model.

[EFFECT OF SYNTHETIC PEPTIDES ON AGING OF PATIENTS WITH CHRONIC POLYMORBIDITY AND ORGANIC BRAIN SYNDROME OF THE CENTRAL NERVOUS SYSTEM IN REMISSION]
Meshchaninov VN, Tkachenko EL, Zharkov SV, Gavrilov IV, Katyreva IuE. · Advances in gerontology = Uspekhi gerontologii (2015) ·

We've estimated the cellular and metabolic part of geroprophylactic effects of short synthetic tripeptides vesugen and pinealon for correction of the biological age. 32 people (18 men, 12 women) aged 41-83 years with polymorbidity and the organic brain syndrome in remission participated in the study.

Peptides tissue-specifically stimulate cell differentiation during their aging
Khavinson VKh, Linkova NS, Polyakova VO, Kheifets OV, Tarnovskaya SI, Kvetnoy IM. · Bulletin of experimental biology and medicine (2012) ·

We verified expression of CXCL12 and Hoxa3 transcription factors of differentiation in cultures of human embryonic pancreatic and bronchial cells and CXCL12 and WEGC1 factors in a culture of human prostatic fibroblasts. Reduced expression of these differentiation markers was detected in late-passage (aging) cultures.

[Biological activity of regulatory peptides in model experiments in vitro]
Kozina LS, Arutiunian AV, Stvolinskiĭ SL, Khavinson VKh. · Advances in gerontology = Uspekhi gerontologii (2008) ·

Biological effects of short regulatory peptides, pinealon, vesugen, vilon and epitalon were studied in model experiments in vitro. These peptides were found not to demonstrate direct antioxidant activity but be able to restrict lipid peroxidation of human lipoproteins by modification of their structure.

[Investigation of antihypoxic properties of short peptides]
Kozina LS. · Advances in gerontology = Uspekhi gerontologii (2008) · animal

The data presented suggest that short regulatory peptides (vilon, epitalon, vesugen and pinealon) have manifested the antihypoxic properties in the model of hypobaric hypoxia. Pinealon (Glu-Asp-Arg) has the most pronounced effect among them.
