Design, Synthesis, Characterization, In silico Evaluation, and Antimicrobial Potential of Novel 1,3,5-Triazine-amino-benzenesulfonamide Derivatives: Part 2

In continuation of our previous work, a series of 1,3,5-triazine–aminobenzenesulfonamide derivatives (A13-A25) was synthesized through sequential nucleophilic substitution reactions of cyanuric chloride and evaluated for their structural, antimicrobial and pharmacokinetic properties. The synthesized compounds were char...

Synthesis and Characterization of Substituted Isoxazolidines through 1,3-Dipolar Cycloaddition and Evaluation of their Antibacterial, Antioxidant and Molecular Docking Studies

A series of substituted isoxazolidine derivatives (3a-g) was synthesized through a 1,3-dipolar [3+2] cycloaddition of a glutaraldehyde-derived nitrone with substituted cinnamaldehyde-derived chalcones. The synthesized derivatives were evaluated for their in vitro antibacterial activity against selected Gram-positive an...

Comparative Synthesis, Spectroscopic Characterization and Concentration-Dependent Antimicrobial Profiling of 8-Substituted 2,5-Dihydro-1,5-Benzothiazepines

A matched library of twelve 8-substituted 2,5-dihydro-1,5-benzothiazepines was synthesized by trifl uoroacetic-acid-catalyzed cyclocondensation of six 5-substituted 2-aminobenzenethiols with either a naphthyl chalcone (series A, 5a–5f) or a 2,4-dichlorophenyl chalcone (series B, 5g–5l). Isolated yields were 60–70%. Str...
