The presently disclosed prodrugs preferentially distribute to healthy tissues including the kidney, lacrimal glands, and salivary glands, which represent sites of off-target binding and toxicity for PSMA-targeted prostate cancer imaging agents and therapies. Accordingly, the 2-PMPA prodrugs can be used to pretreat, bind to, and shield the kidney and salivary glands from PSMA-targeted cytotoxic or radiotherapy.
