Overview

fluproxadine (18f) (formerly [18F]AF78) is a novel fluorine-18-labeled positron emission tomography (PET) radiotracer designed to target the norepinephrine transporter (NET). Developed by researchers at the University Hospital Würzburg, Okayama University, and collaborating institutions, it features a phenethylguanidine scaffold that provides high affinity for NET, comparable to that of endogenous norepinephrine. The tracer is designed for the non-invasive assessment of cardiac sympathetic nerve conditions (such as in congestive heart failure) and the delineation of neuroendocrine tumors (such as neuroblastoma and pheochromocytoma/paraganglioma). Its streamlined, one-step radiosynthesis using an unprotected guanidine precursor overcomes the complex, multi-step radiosynthetic challenges of legacy NET tracers, facilitating clinical translation.
