Radioiodinated celiprolol as a new highly selective radiotracer for β₁-adrenoceptor-myocardial perfusion imaging

Abstract

Abstract The present study was oriented to synthesis radioiodinated celiprolol (Cel) for a potential cardiac imaging. Celiprolol has been labeled using 125 I with chloramine-T (Ch-T) as an oxidizing agent. The key effective factors such as amount of oxidizing agent, amount of substrate, pH, reaction temperature and reaction time, have been systematically studied to optimize the iodination. The biological distribution indicates the suitability of radioiodinated Cel as a novel tracer to image heart.
