Immune Modulator

Vilon

Also known as: Lys-Glu

Vilon is a synthetic dipeptide (Lys-Glu / KE) from the Khavinson bioregulator series, originally derived from thymus extracts and studied in Russian preclinical models as an immunomodulator and geroprotector. Not FDA-approved; all published evidence originates from a single research group.

Secondary-Amine Relay Enables Lysine-Directed Multicomponent Functionalization of Peptides

Multicomponent reactions provide powerful modularity for peptide functionalization, but their application to lysine residues remains limited by the low efficiency of direct primary-amine-based activation pathways under peptide-compatible conditions.

Overview of Epitalon-Highly Bioactive Pineal Tetrapeptide with Promising Properties

Epitalon, also known as Epithalon or Epithalone, is a tetrapeptide, Ala-Glu-Asp-Gly (AEDG), which was synthesized based on the amino acids composition of Epithalamin, a bovine pineal gland extract, prior to its discovery in pineal gland polypeptide complex solution.

Hyoid bone-based sex discrimination among Egyptians using a multidetector computed tomography: discriminant function analysis, meta-analysis, and artificial intelligence-assisted study

The hyoid bone has been identified as sexually dimorphic in various populations. The current study is a forerunner analysis that used three-dimensional multidetector computed tomography (3D MDCT) images of the hyoid bone to examine sexual dimorphism in the Egyptian population.
