§ 01   Overview

Overview

Synthetic pentapeptide (Arg-Lys-Asp-Val-Tyr) corresponding to residues 32–36 of thymopoietin. Approved in Italy and China for immune modulation in chronic infection, rheumatoid arthritis, and hepatitis B; not FDA-approved.

Multiple European / Asian controlled trials. Italian RA and HBV studies. Not FDA-approved; limited Western post-2000 literature.

§ 02   Mechanism

Mechanism of action

Thymopentin represents the minimum active region of thymopoietin. It binds surface receptors on T-cell precursors to promote maturation and regulate helper/suppressor balance, with anti-inflammatory and antiviral adjunct effects.
