LABELED INHIBITORS OF PROSTATE SPECIFIC MEMBRANE ANTIGEN (PSMA), BIOLOGICAL EVALUATION, AND USE AS IMAGING AGENTS

摘要

The prostate-specific membrane antigen (PSMA) is increasingly recognized as a viable target for imaging and therapy of cancer. Various 99mTc/Re-labeled compounds were prepared by attaching known Tc/Re chelating agents to an amino-functionalized PSMA inhibitor with or without a variable length linker moiety. Ex vivo biodistribution and in vivo imaging demonstrated the degree of specific binding to engineered PSMA+PC3 PIP tumors.
