Abstract: | A new hybrid polydentate template comprising distinctive pharmacophoric groups, namely, ibuprofen, 1,3,4‐oxadiazole, and 1,2,3‐triazole linked through a thioether bridge was achieved by one‐pot synthesis by exploring multicomponent Cu‐catalyzed “click chemistry” approach. The target structures were characterized by NMR, IR, and LC‐Mass. The X‐ray analysis of 2‐(1‐(4‐isobutylphenyl)ethyl)‐5‐(((1‐(3‐nitrophenyl)‐1H‐1,2,3‐triazol‐4‐yl)methyl)thio)‐1,3,4‐oxadiazole ( 8a ) confirmed the assigned structure. The in vitro antibacterial and anticancer activity of these compounds revealed that 2‐(1‐(4‐isobutylphenyl)ethyl)‐5‐(((1‐phenyl‐1H‐1,2,3‐triazol‐4‐yl)methyl)thio)‐1,3,4‐oxadiazole ( 8b ) demonstrated more potent antibacterial activity against Gram‐negative strains (Escherichia coli and Pseudomonas aeruginosa) and 2‐(((1‐(2,4‐dimethylphenyl)‐1H‐1,2,3‐triazol‐4‐yl)methyl)thio)‐5‐(1‐(4 isobutylphenyl)ethyl)‐1,3,4‐oxadiazole ( 8e ) exhibited anticancer activity with IC50 of 27.50 and 31.03 μg/mL against HeLa and MCF‐7 cell lines, respectively. |
