Poly(adenosine diphosphate ribose) polymerase (PARP) has emerged as an effective therapeutic strategy against cancer that targets the DNA damage repair enzyme. PARP-targeting compounds radiolabeled with Auger electron–emitting radionuclide can be trapped close to damaged in tumor tissue, where high ionizing potential and short range lead electrons kill cells through creation of complex damage, minimal surrounding normal tissue. Here, we report on [<sup>123</sup>I]CC1, <sup>123</sup>I-labeled...
