Thymocartin
Also known as: RKDV, Thymocartin, Thymopentin fragment 32-35, TP-4
Summary
Thymocartin is a synthetic tetrapeptide (Arg-Lys-Asp-Val) corresponding to the active region of thymopoietin (residues 32–35). It was investigated as an immunostimulatory agent capable of inducing T-cell differentiation, with potential applications in immunodeficiency states and as an adjunct in oncology. It has not achieved broad clinical approval and remains largely a research compound.
Mechanism of Action
Thymocartin (TP-4) is a tetrapeptide fragment derived from thymopoietin that binds to T-lymphocyte precursors and promotes T-cell differentiation and maturation by modulating cAMP levels and lymphocyte surface marker expression.
