Abstract

Herein we report, for the first time, the development, labeling optimization and preliminary biodistribution studies of an [18F] radiolabeled meso-tetraphenylporphyrin. After synthesis and characterization of the “cold” fluorinated porphyrin, the conditions have been transferred to an automated radiochemistry module and the desired 5-(2-[18F]fluoroethoxyphenyl)-10,15,20-triphenylporphyrin was prepared in a radiochemical purity >95%. Moreover, data regarding the uptake into human bladder tumor cells and the radiotracer biodistribution after C57BL/6 mice injection are also presented. The maximum cellular uptake was reached at 45 min and was of 2.5%.
