Lys(CO-C3-p-I-Ph)-O-tBu is a pharmacokinetic modifier (PK modifier) that can improve the PK properties of PSMA ligand molecules. Lys(CO-C3-p-I-Ph)-O-tBu can increase the residence time of PSMA ligand in plasma by increasing its binding capacity to albumin. Lys(CO-C3-p-I-Ph)-O-tBu also reduces salivary gland absorption, possibly extending the half-life of the active compound. Ac-PSMA-trillium is a suitable PSMA-targeting compound that has different biological applications after modification with different radioactive isotopes. If labeled with 111In, it can be used as DOTA chelating agent and imaging agent. Or labeled with 225Ac as a Macropa chelator for targeted radionuclide therapy (TRT) in the study of metastatic castration-resistant prostate cancer (mCRPC)[1][2]. | [References]
