Abstract A novel series of 1-(3-Methyl-3-mesityl)-cyclobutyl-2-[5-(2-fluorophenyl)-4-(aryl-alkyl)-4H-[1,2,4]triazol-3-yl]sulfanyl}-ethanone compounds were synthesized by a condensation reaction. The new compounds were characterized by elemental analyses, FT-IR and 1H, 13C NMR techniques. The antioxidant and antibacterial properties of the synthesized compounds were also investigated.

compounds were confirmed by elemental analyses, FT-IR, 1H-NMR and 13C-NMR. The antioxidant and antitumor properties of the synthesized compounds were also investigated. Three of the triazole derivatives with p-tolyl, benzyl and phenyl substituents (5c–e) displayed good antioxidant and antitumoractivity in comparison to the standards. Graphical Abstract
A series of Schiff bases, combining 2,4-disubstituted thiazole and cyclobutane rings, and hydrazone moieties in the same molecule, was synthesized, characterized and evaluated for screening antibacterial and antifungal activities on microorganisms, respectively, on four bacteria and Candida tropicalis. The structures of original compounds were confirmed by analytical and spectroscopic (FT-IR, (1)H
