Two series of new compounds containing 1,2,3-triazole moiety were designed as putative GlyT1 inhibitors aiming the discovery of new hits with activity in cognitive disorders. 1,4-disubstituted α-hydroxy-1,2,3-triazoles I [Ar = Ph, 4-BrC6H4, 4-C(O)MeC6H4, etc.; X = H, Br, Ph, etc.; Y = CH, N; Z = H, Br] were obtained as racemates in moderate to good yields by the copper-catalyzed azide-alkyne cycloaddition reaction (click chem.) as the key step between propargyl alcs. and aryl azides, previously prepared from anilines or boronic acids. Benzo[c]chromene-triazoles were planned to be obtained by palladium-catalyzed C-H activation using [bis(trifluoroacetoxy)iodobenzene] of some compounds I, since benzo[c]chromenes were also privileged groups with several biol. activities, including to the central nervous system. Unexpectedly, 9H-fluorenes-1,2,3-triazoles II [R = F, OMe, C(O)Me] instead of benzo[c]chromene-triazoles, were obtained by Friedel-Crafts alkylation reaction of compounds I [Ar = 4-MeOC6H4, 4-FC6H4, 4-C(O)MeC6H4; X = Ph; Y = CH; Z = H]. Two series of compounds I and II were tested for inhibition of the glycine transporter (rat GlyT1 isoform) but only compound I [Ar = 4-BrC6H4; X = Br; Y = CH; Z = H] was active (half maximal inhibitory concentration (IC50) = 8.0μM). The experimental part of the paper was very detailed, including the reaction process of 2-Bromonicotinaldehyde(cas: 128071-75-0HPLC of Formula: 128071-75-0)
2-Bromonicotinaldehyde(cas: 128071-75-0) belongs to pyridine. In industry and in the lab, pyridine is used as a reaction solvent, particularly when its basicity is useful, and as a starting material for synthesizing some herbicides, fungicides, and antiseptics.HPLC of Formula: 128071-75-0
