Synthetic Route of 566169-93-5. Let¡¯s face it, organic chemistry can seem difficult to learn. Especially from a beginner¡¯s point of view. Like 566169-93-5, Name is 2-(4-(Methylamino)phenyl)benzo[d]thiazol-6-ol. In a document type is Article, introducing its new discovery.
Maillard reaction of 18F-FDG with biological amines results in the formation of 18F-fluorodeoxyglycosylamines (18F-FDGly) as pseudo-Amadori products. To increase in vivo stability, we report the reductive amination of FDGly to provide reduced fluorodeoxyglucamines (FDGlu). 18F-Fluorodeoxyglucamines (18F-FDGlu), resulting from linking 18F-FDG (hydrophilic) to lipophilic molecules containing amine group may be useful as positron emission tomography (PET) imaging agents. Two amine derivatives, 7-chloro-8-hydroxy-3-methyl-l-(3?-aminophenyl)-2,3,4,5-tetrahydro-lH-3-benzazepine (SCH 38548 for dopamine D1 receptors) and BTA-0 (for Abeta amyloid) were reacted with FDG under reductive amination conditions to yield stable products, FDGluSCH and FDGluBTA. FDGluSCH had high binding affinity to rat brain dopamine D1 receptors with a Ki of 19.5 nM while FDGluBTA had micromolar affinity for human frontal cortex Abeta plaques. 18F-FDGluSCH was prepared in low to modest radiochemical yields and preliminary results showed binding to the rat striatum in brain slices. In vivo stability of 18F-FDGluSCH needs to be determined. Our results suggest that 18F-FDG is a useful ‘radioactive synthon’ for PET radiotracer development. Its usefulness will have to be determined on the basis of the structure-activity relationship of the target molecule.
