Exploration of Thioxolone Derivatives: Synthesis, Docking Studies, and Biological Evaluation for Antibacterial and Antidiabetic Activities

ChemistrySelect, Volume 10, Issue 38, October 13, 2025.
Thioxolone derivatives are evaluated for antibacterial and anti‐diabetic potential. Compounds T‐11, T‐12, and T‐13 exhibit potent antibacterial activity against E. coli, B. cereus, and S. aureus, with low MIC values. T‐11 and T‐3 show stronger α‐glucosidase inhibition than acarbose, while molecular docking reveals T‐13 as the strongest binder ...
