A practical method for the synthesis of 3,5-disubstituted isoxazoles via cyclization of β-fluoro enones with sodium azide was disclosed. Density functional theory (DFT) calculation indicated that both (1) the azirine formation followed by intramolecular rearrangement and (2) direct enolate O-attack via 5-exo-trig cyclization of vinyl azide were possible for the isoxazole formation.

Isoxazole-triazole conjugates (8a-q) were synthesized using click chemistry approach and their biological activities were explored to develop novel antibacterial agents. In vitro antibacterial screening against Gram-positive as well as Gram-negative bacterial strains identified compounds 8b and 8m with potent inhibitory potential against selective bacterial cells. 8b showed IC50 value of 67.6 μg/mL against P. aeruginosa while 8m exhibited better activity against Gram-positive bacteria S. pneumoniae and E. faecalis having IC50 values 74.13 and 44.7 μg/mL, respectively. Effect on growth kinetics of the bacterial cells as well as cytotoxicity studies on human embryonic kidney cells (HEK293) further supports their biological potential. Compound 8m significantly inhibited biofilm formation of E. coli cells visualized by scanning electron microscopy (SEM) analysis. The interaction of these compounds with ctDNA, as their possible mode of action, was studied using multi-spectroscopic techniques and molecular docking. The data suggested that compound 8m intercalate in the minor groove of DNA.

Antibiotic resistance among clinically significant bacterial pathogens is becoming a prevalent threat to public health, and new antibacterial agents with novel mechanisms of action hence are in an urgent need. Utilizing computational docking method and structure-based optimization strategy, we rationally designed and synthesized two series of isoxazol-3-yl- and isoxazol-5-yl-containing benzamide derivatives that targeted the bacterial cell division protein FtsZ. Evaluation of their activity against a panel of Gram-positive and -negative pathogens revealed that compounds B14 and B16 that possessed the isoxazol-5-yl group showed strong antibacterial activity against various testing strains, including methicillin-resistant Staphylococcus aureus and penicillin-resistant S. aureus. Further molecular biological studies and docking analyses proved that the compound functioned as an effective inhibitor to alter the dynamics of FtsZ self-polymerization via a stimulatory mechanism, which finally terminated the cell division and caused cell death. Taken together, these results could suggest a promising chemotype for development of new FtsZ-targeting bactericidal agent.
