A library of some novel 1,4-disubstituted-1,2,3-triazole-thiosemicarbazone hybrid molecules were designed and synthesized from (4-Prop-2-ynyloxy-benzylidene)-thiosemicarbazone and aryl azides under Cu(I)-catalyzed cycloaddition reaction. All newly synthesized [4-(1-Benzyl-1H-[1,2,3]triazol-4-ylmethoxy)-benzylidene] -thiosemicarbazone hybrid molecules were efficiently characterized by IR, 1H NMR, 13C NMR, HRMS and structure of alkynes 3 & 12 were finally supported by X-ray crystallographic data. Compounds 5c, 5d, 9c, 9d 13c and 13d demonstrated excellent potency results for B. Subtilis and P. Aeruginosa bacterial strains with MIC values 0.0141, 0.0152, 0.0562, 0.0608, 0.0141, 0.0608, 0.0141, 0.0304, 0.0281, 0.0304, 0.0281, 0.0304, respectively as compared to reference drug Ciprofloxacin. Antibacterial activity results were supported by molecular docking and DFT studies.

Some biologically active semicarbazone-triazole hybrid molecules have been designed and synthesized from semicarbazone linked terminal alkyne and aromatic azides via Cu(i)-catalyzed cycloaddition reactions. All newly synthesized compounds were successfully characterized by using IR, 1H-NMR, 13C-NMR, and HRMS spectral techniques. The synthesized molecules were screened in vitro for anti-bactericidal effects on E. coli (MTCC 16521), B. subtilis (MTCC441), S. aureus (MTCC 3160), P. aeruginosa (MTCC 424) and S. epidermidis (MTCC 6880). The antibacterial property results revealed that the semicarbazone-triazole hybrid molecules (9b, 9e, and 9f) are a better alternative to the existing antibacterial drug ciprofloxacin. The docking study on the most active compound 9b and its alkyne precursor 8 with the DNA gyrase enzyme of E. coli bacteria supported the biological activity results.

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.
