DOTA-Pep-1L TFA
Based on 1 Customer Validation
DOTA-Pep-1L TFA is a polypeptide formed by the conjugation of DOTA and Pep-1L. DOTA-Pep-1L TFA specifically binds to IL13RA2 and can be used for the synthesis of targeted polypeptides. DOTA-Pep-1L TFA yields the isotopically labeled product [225Ac]DOTA-Pep-1L, which exerts α-radiation killing effects on orthotopic glioma cells and extends the median survival time of mice bearing orthotopic glioma models after stereotactic injection. DOTA-Pep-1L TFA can be used for PET imaging, tumor targeting and glioma research.

DOTA-Pep-1L labeled with [225Ac] (1 µCi (0.04 MBq); intracranial infusion via convection-enhanced delivery; single dose) TFA is well-tolerated and provides significant anti-glioblastoma efficacy, as evidenced by a median survival of 41 days, reduced tumor volume, and induction of tumor cell death and reduced proliferation in orthotopic U251 glioblastoma-bearing mice[2].
