Abstract
A new series of furo[2,3-d]pyrimidine-1,3,4-oxadiazole hybrid derivatives were synthesized via an environmentally friendly, multistep synthetic tool and a one-pot Songoashira-heterocyclization protocol using, for the first time, nanostructured palladium pyrophosphate (Na2 PdP2 O7 ) as a heterogeneous catalyst. Compounds 9a-c exhibited broad-spectrum activity with low micromolar EC50 values toward wild and mutant varicella-zoster virus (VZV) strains. Compound 9b was up to threefold more potent than the reference drug acyclovir against thymidine kinase-deficient VZV strains. Importantly, derivative 9b was not cytostatic at the maximum tested concentration (CC50 > 100 µM) and had an acceptable selectivity index value of up to 7.8. Moreover, all synthesized 1,3,4-oxadiazole hybrids were evaluated for their cytotoxic activity in four human cancer cell lines: fibrosarcoma (HT-1080), breast (MCF-7 and MDA-MB-231), and lung carcinoma (A549). Data showed that compound 8f exhibits moderate cytotoxicity, with IC50 values ranging from 13.89 to 19.43 µM. Besides, compound 8f induced apoptosis through caspase 3/7 activation, cell death independently of the mitochondrial pathway, and cell cycle arrest in the S phase for HT1080 cells and the G1/M phase for A549 cells. Finally, the molecular docking study confirmed that the anticancer activity of the synthesized compounds is mediated by the activation of caspase 3.

Abstract
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 μM 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-phenylenebis(oxy))bis(methylene))bis(1H-1,2,3-triazole-4,1 diyl)) dibenzaldehyde) were the most promising, with an EC50 of 16 and 21 μM and CC50 of 285 and 2,593 μM, 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.

Abstract
An efficient three-step synthesis of a new heterocyclic system is described wherein the 2H-bis([1,2,3]triazolo)[5,1-a:4',5'-c]isoquinoline ring system is elaborated using a simple synthetic strategy. The approach permits the preparation of target compounds in high yields using readily available arylhydrazines and o-alkynylbenzaldehydes as starting materials. The photophysical properties of the prepared heterocycles were studied to demonstrate that the prepared compounds are attractive blue-emitting fluorophores, exhibiting quantum yields up to 98% and Stokes shifts up to 67 nm. A strong effect of the steric hindrance on the absorption and emission spectra was revealed.

Abstract
An efficient direct approach to triazole-fused sultams has been developed. The key step of the proposed strategy is base-mediated cyclization of sulfonamide-tethered 5-iodo-1,2,3-triazoles which are readily available via an improved protocol for Cu-catalyzed 1,3-dipolar cycloaddition. The annulation of the sultam fragment to the triazole ring proceeds smoothly under transition-metal-free conditions in the presence of Cs2CO3 in dioxane at 100 °C and affords fused heterocycles in high yields up to 99%. The favorability of an SNAr-like mechanism for the cyclization was supported by DFT calculations. The applicability of the developed procedure to modification of natural compounds was demonstrated by preparation of a deoxycholic acid derivative.

Abstract
:
Thio-, seleno-substituted triazoles are useful scaffolds employed in the fields of
organic synthesis, medicinal chemistry, and material science. A number of synthetic approaches
to efficient formation of thio- and seleno-triazoles have been disclosed, including
the interception of copper(I) triazolides generated in-situ, cycloaddition of internal alkynes
(thio-, halo-, and metalated alkynes) to azides, and the coupling of azides and nonalkyne
substrates. This mini-review intends to summarize the synthetic methods toward
thio-, seleno-1,2,3-triazoles and the relative reaction mechanisms.
