The article was titled 《Development of a carbon-11 PET radiotracer for imaging TRPC5 in the brain》. The information in the text is summarized as follows:
The transient receptor potential channel subfamily member 5 (TRPC5) is a calcium permeable cation channel widely expressed in the brain. Accumulating evidence indicates that it plays a crucial role in psychiatric disorders including depression and anxiety. Positron emission tomog. (PET) combined with a TRPC5 specific radioligand may provide a unique tool to investigate the functions of TRPC5 in animal disease models to guide drug development targeting TRPC5. To develop a TRPC5 PET radiotracer, the potent TRPC5 inhibitor HC608 was chosen for C-11 radiosynthesis through the N-demethyl amide precursor 7 reacting with [11C]methyl iodide. Under optimized conditions, [11C]HC608 was achieved with good radiochem. yield (25 ± 5%), high chem. and radiochem. purity (>99%), and high specific activity (204-377 GBq μmol-1, decay corrected to the end of bombardment, EOB). The in vitro autoradiog. study revealed that [11C]HC608 specifically binds to TRPC5. Moreover, initial in vivo evaluation of [11C]HC608 performed in rodents and the microPET study in the brain of non-human primates further demonstrated that [11C]HC608 was able to penetrate the blood brain barrier and sufficiently accumulate in the brain. These results suggest that [11C]HC608 has the potential to be a PET tracer for imaging TRPC5 in vivo. The experimental part of the paper was very detailed, including the reaction process of 1-(Bromomethyl)-4-chlorobenzene(cas: 622-95-7Related Products of 622-95-7)
1-(Bromomethyl)-4-chlorobenzene(cas: 622-95-7) may be used to synthesize 1-(4-chlorobenzyl)-2-(pyrrolidin-1-yl-methyl)-1H-benzimidazole dihydrochloride.Related Products of 622-95-7 It can be synthesized by reacting 4-chlorobenzyl alcohol with bromodimethylsulfonium bromide (BDMS) It can also be synthesized by refluxing a mixture of 4-chlorobenzaldehyde, chlorotrimethylsilane, 1,1,3,3-tetramethyldisiloxane and lithium bromide.
