existing limitations and increase survival rates is a highly desirable goal. In the current
investigation, pirarubicin, a new generation antineoplastic anthracycline, was labeled with
[125 I] via an electrophilic substitution reaction. The reaction parameters were studied to
optimize the iodination process. The labeled compound showed high radiochemical yield
(98.5±2.1%) and consistently remained above 90% for more than 20 h at room temperature …
