Description

Thymopoietin II (32-36)-Ethyl Ester CAS NO 283167-49-7 is a synthetic pentapeptide fragment derived from the thymic hormone thymopoietin, specifically corresponding to residues 32-36 with an ethyl ester modification. This compound is of significant interest for its role in immunological research and as a key intermediate in the development of novel therapeutic agents. It is primarily utilized by research institutions and pharmaceutical developers focused on immunomodulation, T-cell differentiation studies, and peptide-based drug discovery.

Application

• Immunological Research: Used as a reference standard and active agent in studies investigating T-cell maturation, differentiation, and function.
• Pharmaceutical Intermediates: Serves as a critical building block in the synthesis of longer peptide sequences or analogs with potential therapeutic applications.
• Biochemical Assay Development: Employed in the development and validation of bioassays targeting thymic hormone activity.
• Cell Culture Studies: Applied in *in vitro* models to study its effects on lymphocyte proliferation and immune system modulation.
• Peptide Chemistry: A valuable substrate for studying structure-activity relationships (SAR) and for the preparation of conjugated or labeled peptide derivatives.
