Thymogen
Also known as: Thymagen
Thymogen (also marketed as Thymagen) is a synthetic dipeptide, L-Glu-L-Trp (Glu-Trp), originally isolated by the Khavinson group from the calf-thymus polypeptide complex Thymalin and then synthesized. It is registered as a pharmaceutical in Russia for immunocorrection (nasal drops / IM injection). Not FDA-approved in the US; research-use only.

Hepatoprotective Effects of Thymogen Analogues in Hydrazine Hepatopathy in Rats
We studied the reparative and antioxidant effects of thymogen (10 and 100 μg/kg) and its modifications in equimolar doses (12 and 120 μg/kg) obtained by attaching the amino acid D-alanine (D-Ala) to the N- or C-terminus of the peptide molecule.

The First Reciprocal Activities of Chiral Peptide Pharmaceuticals: Thymogen and Thymodepressin, as Examples
Peptides show high promise in the targeting and intracellular delivery of next-generation biotherapeutics. The main limitation is peptides' susceptibility to proteolysis in biological systems. Numerous strategies have been developed to overcome this challenge by chemically enhancing the resistance to proteolysis.

Advancement from Small Peptide Pharmaceuticals to Orally Active Piperazine-2,5-dion-Based Cyclopeptides
The oral delivery of peptide pharmaceuticals has long been a fundamental challenge in drug development. A new chemical platform was designed based on branched piperazine-2,5-diones for creating orally available biologically active peptidomimetics.

Peptides Regulating Proliferative Activity and Inflammatory Pathways in the Monocyte/Macrophage THP-1 Cell Line
This study evaluates the effects of five different peptides, the Epitalon ® tetrapeptide, the Vilon ® dipeptide, the Thymogen ® dipeptide, the Thymalin ® peptide complex, and the Chonluten ® tripeptide, as regulators of inflammatory and proliferative processes in the human monocytic THP-1, which is a human leukemia mon…
