Royal Peptides supplies compounds intended for controlled laboratory research and analytical applications.
Research onlyLaboratory materialAnalytical use
Where applicable, Royal Peptides research materials are supplied in lyophilized form. Lyophilization is a freeze-drying process used to remove moisture from material under controlled conditions.
Storage requirements may vary by compound, formulation and production lot. Refer to the product label and available product-specific documentation.
Packaging components may vary slightly between production lots. This can include vial closures, cap styles, label positioning and external packaging.

Peptide bioregulators are ultra-short peptides, just 2 to 4 amino acids long. They were first isolated from specific animal organs and tissues and are now made synthetically to an exact sequence. The field was founded by Prof. Vladimir Khavinson and colleagues at the St. Petersburg Institute of Bioregulation and Gerontology, and they are often called Khavinson peptides.
Most published work is preclinical and comes mainly from one research school. Independent data is still limited.
| Peptide | Sequence | Class | Tissue focus |
|---|---|---|---|
| Bronchogen | Ala-Glu-Asp-Leu | Tetrapeptide | Bronchial and respiratory tissue |
| Cartalax | Ala-Glu-Asp | Tripeptide | Cartilage and connective tissue |
| Livagen | Lys-Glu-Asp-Ala | Tetrapeptide | Hepatic tissue and chromatin |

Sequence: Ala-Glu-Asp-Leu (AEDL peptide) · Formula: C18H30N4O9 · MW: 446.46 g/mol
Bronchogen is a synthetic tetrapeptide bioregulator (Ala-Glu-Asp-Leu) from the Khavinson series of short tissue-specific peptides. It was developed from research into peptide complexes isolated from bronchial mucosa. Bronchogen has been studied mainly in cell and rodent models of the bronchial epithelium. Published work from the St. Petersburg Institute of Bioregulation and Gerontology has looked at how it may influence epithelial differentiation markers and the gene expression of airway lining cells. Like other bioregulators, it is investigated as a possible gene-level signalling molecule rather than a receptor agonist.
Sequence: Ala-Glu-Asp (AED peptide) · Formula: C12H19N3O8 · MW: 333.30 g/mol
Cartalax is a synthetic tripeptide bioregulator (Ala-Glu-Asp) from the Khavinson series, associated with cartilage and connective tissue. Its link to cartilage comes from the Khavinson group, which patented Ala-Glu-Asp for bone and cartilage tissue metabolism. Most of the published lab work is in other cell types. In ageing skin fibroblasts, AED raised the cell-division marker Ki-67, reduced the matrix-degrading enzyme MMP-9 and suppressed caspase-dependent apoptosis (Lin’kova et al., 2016), and it has also been studied in kidney tissue cultures. Nearly all of this research comes from one group and has not been independently replicated.
Sequence: Lys-Glu-Asp-Ala (KEDA peptide) · Formula: C18H31N5O9 · MW: 461.47 g/mol
Livagen is a synthetic tetrapeptide bioregulator (Lys-Glu-Asp-Ala) from the Khavinson series, associated with liver tissue. Livagen is best known in the literature for chromatin research. Studies on lymphocytes from older donors reported that it may decondense heterochromatin, the tightly packed DNA that tends to build up with cellular ageing, and so make silenced genes accessible again. It has also been examined in hepatic tissue and enzyme-activity models.
Sequence: Glu-Asp-Arg (EDR peptide) · Formula: C15H26N6O8 · MW: 418.41 g/mol
Pinealon is a synthetic tripeptide bioregulator (Glu-Asp-Arg) from the Khavinson series, associated with neural tissue. Pinealon has been studied in neuronal cell cultures, including cerebellar granule cells exposed to oxidative stress, where researchers measured reactive oxygen species and cell viability. It has also appeared in rodent studies of prenatal hypoxia. Its very small size has made it a model compound for studying whether short peptides can reach the cell nucleus and interact with DNA.
Sequence: Glu-Asp (ED dipeptide) · Formula: C9H14N2O7 · MW: 262.22 g/mol
Vesilute is a synthetic dipeptide bioregulator (Glu-Asp) from the Khavinson series, associated with bladder and urogenital tissue. Vesilute belongs to the group of peptides developed from research on bladder tissue extracts. As one of the smallest bioregulators, just two amino acids, it is studied in urogenital tissue and cell models. Most of the published work is in Russian-language literature, and independent data is limited.
Sequence: Lys-Glu-Asp (KED peptide) · Formula: C15H26N4O8 · MW: 390.39 g/mol
Vesugen is a synthetic tripeptide bioregulator (Lys-Glu-Asp) from the Khavinson series, associated with the vascular wall. Vesugen has been studied in vascular endothelial cell models, the cells lining blood vessels, including work on markers of cellular ageing and proliferation in cultured vascular cells. It is used as a research tool for exploring how tissue-specific short peptides may affect gene expression in the vascular system.
Sequence: Lys-Glu (KE dipeptide) · Formula: C11H21N3O5 · MW: 275.31 g/mol
Vilon is a synthetic dipeptide bioregulator (Lys-Glu) and one of the earliest compounds in the Khavinson series. It was developed from research on thymus-derived peptide preparations. Vilon is among the most-cited bioregulators. It has been used in gene-expression microarray studies, in chromatin research, and in rodent work on thymic and immune parameters and lifespan. Because it is so short, it is often used as a reference compound when comparing how different short peptides affect gene expression.
