This review summarises the literature on the synthesis and applications of fluorescently labelled carbohydrates. Due to the sensitivity of fluorescent detection, this approach provides a useful tool to study processes involving glycans. A few general categories of labelling are presented, in situ labelling of carbohydrates with fluorophores, fluorescently labelled glycolipids, fluorogenic glycans, pre-formed fluorescent glycans for intracellular applications, glycan-decorated fluorescent polymers, fluorescent glyconanoparticles, and other functional fluorescent glycans. © 2015 Springer Science+Business Media New York.

Hydroxyzine and aripiprazole are active pharmaceutical ingredients that have been largely acknowledged for their antipsychotic properties. Deuterium labeled isotopes of hydroxyzine and aripiprazole are internal standards that can aid in the further research of non-isotopic forms via quantification analysis using HPLC-MS/MS. The synthesis of hydroxyzine-d8 was accomplished by coupling piperazine-d8 with 4-chlorobenzhydryl chloride followed by the reaction of the first intermediate with 2-(2-chloroethoxy) ethanol to afford 11.7% of hydroxyzine-d8 with 99.5% purity. The synthesis of aripiprazole-d8 was also achieved in two steps. 1,4-Dibromobutane-d8 reacted with 7-hydroxy-3,4-dihydro-2(1H)-quinolinone. The first intermediate was then coupled with 1-(2, 3-dichlorophenyl)piperazine hydrochloride to produce 33.4% of aripiprazole-d8 with 99.93% purity. © 2015 John Wiley & Sons, Ltd.
