Modifying Antibiotic Activity of Synthetic Thiadiazine Analogs Against MDR Bacteria and ADMET Analysis

open access: yesChemistryOpen, EarlyView.
The study demonstrated that thidiazine compounds potentiated the action of antibiotics. The compounds associated with norfloxacin against S. aureus showed greater significance in relation to the other medications. The indiscriminate use of antibiotics has led to the selection of resistant bacterial strains, significantly reducing the effectiveness of ...
