The translocator protein (TSPO) is an attractive target for tumor imaging due to its up-regulation in numerous cancer cell types. Here, we report a series of functional TSPO ligands, n-TSPOmbb732, which can be conjugated to a variety of signaling moieties and are widely applicable in TSPO-targeted molecular imaging. Two fluorescent dye-labeled 6-TSPOmbb732 displayed nanomolar binding affinities to TSPO and were successfully imaged in vitro.
