Azides and acetylenes are bio-orthogonal functional groups that can be readily coupled using copper(I)- or ruthenium(II)- catalyzed 1,3-dipolar cycloaddition reactions. Using non-fluorescent aromatic azides and aromatic acetylenes, covering a range of electron rich and poor building blocks, the Huisgen cycloaddition afford 1,4-disubstituted or 1,5-disubstituted 1,2,3-triazoles. Using a combinatorial approach by running reaction in parallel in polypropylene 96-well plates we discovered several new fluorescent 1,2,3-triazoles scaffolds. These compounds show diverse interactions with biomolecules that could find applications in biology in, for example, fluorescence microscopy or biomolecule quantification.

This report describes the synthesis of a carbon nanotube-bound dendrimer and three carbon nanotube-bound monometallic complexes and their use as catalysts. The polyamidoamine third generation dendrimer used here incorporates pyrazole-triazole moieties suitable for ligating iridium(III) centres. The monometallic complexes use the same pyrazole-triazole ligands coordinated to an iridium(III) centre. All catalysts were characterized using ICP-AES and XPS to evaluate their metal loadings on the carbon surface with significantly higher relative weight percentage of iridium determined for the denrimeric species. The catalytic activity and practicality of the formed catalysts were tested using two different intramolecular hydroamination reactions.

Background: Herpes simplex virus 1 (HSV-1) affects a large part of the adult population. Anti-HSV-1 drugs, such as acyclovir, target thymidine kinase and viral DNA polymerase. However, the emerging of resistance of HSV-1 alerts for the urgency in developing new antivirals with other therapeutic targets. Thus, this study evaluated a series of 1,4-disubstituted-1,2,3-triazole derivatives against HSV-1 acute infection and provided deeper insights into the possible mechanisms of action. Methods: Human fibroblast cells (HFL-1) were infected with HSV-1 17syn+ and treated with the triazole compounds at 50 mM for 24 h. The 50% effective drug concentration (EC50) was determined for the active compounds. Their cytotoxicity was also evaluated in HFL-1 with the 50% cytotoxic concentration (CC50) determined using CellTiter-Glo solution. The most promising compounds were evaluated by virucidal activity and influence on virus egress, DNA replication and transcription, and effect on an acyclovir-resistant HSV-1 strain. Results: Compounds 3 ((E)-4-methyl-N'-(2-(4(phenoxymethyl)-1H-1,2,3-triazol1yl)benzylidene)benzenesulfonohydrazide) and 4 (2,2'-(4,4'-((1,3-phenylen ebis(oxy))bis(methylene))bis(1H-1,2,3-triazole-4,1 diyl)) dibenzaldehyde) were the most promising, with an EC50 of 16 and 21 mM and CC50 of 285 and 2,593 mM, respectively. Compound 3 was able to inhibit acyclovir-resistant strain replication and to interfere with virus egress. Both compounds did not affect viral DNA replication, but inhibited significantly the expression of ICP0, ICP4 and gC. Compound 4 also affected the transcription of UL30 and ICP34.5. Conclusions: Our findings demonstrated that these compounds are promising antiviral candidates with different mechanisms of action from acyclovir and further studies are merited.

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 were obtained as racemates in moderate to good yields by the copper-catalyzed azide-alkyne cycloaddition (CuAAC) reaction (click chemistry) as the key step between propargyl alcohols 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] (PhI(TFA)2) of some α-hydroxy-1,2,3-triazoles, since benzo[c]chromenes are also privileged groups with several biological activities, including to the central nervous system. Unexpectedly, 9H-fluorenes-1,2,3-triazoles, instead of benzo[c]chromenetriazoles, were obtained by Friedel-Crafts alkylation reaction. The two series of compounds were tested for inhibition of the glycine transporter (rat GlyT1 isoform) but only the α-hydroxy-1,2,3-triazole 9b was active (half maximal inhibitory concentration (IC50) = 8.0 μM).
