An one-pot two-step automated synthesis of [18F]T807 injection, its biodistribution in mice and monkeys, and a preliminary study in humans

[18F]T807 is a potent tau protein imaging agent. In order to fulfill the demand from preclinical and clinical studies, we developed an automated one-pot two-step synthesis of this potent tau imaging agent and studied its stability, and dosimetr

Synthesis of dicationic carbazole and 4′-amino-(3,3'-bipyridine)-4-ol and the spectral characteristics of carbazoles

The dicationic carbazole compound, 3,6-dimethyl-3,6-diazacarbazole diiodide (8) was prepared with 3-bromopyridine as a starting material by a six-step synthesis. The intermediates and target compound were confirmed by IR, NMR and MS. Meanwhile, UV-visible and fluorescent characteristics of 3,6-diazacarbazole (7) and 3,6-dimethyl-3,6-diazacarbazole diiodide (8) were investigated. It was found that fluorescence decay over time of dicationic carbazole existed in low ionic strength and high ionic strength could stabilize the fluorescence of dicationic carbazole.
