Apexbio Technology LLC Sulbactam sodium 69388-84-7 10mM (in 1mL H2O)
Sulbactam sodium is a competitive and irreversible inhibitor targeting -lactamase enzymes It functions predominantly through binding the active site of -lactamases thereby obstructing these enzymes from hydrolyzing -lactam antibiotics Widely employed in biomedical research Sulbactam sodium is utilized for evaluating bacterial resistance mechanisms characterizing susceptibility profiles of -lactamase-expressing clinical isolates and examining synergistic therapeutic combinations Moreover Sulbactam sodium itself exhibits antimicrobial activity notably against Acinetobacter species clinically resistant to common antibiotics In antibacterial assays against certain -lactamase-producing bacterial strains Sulbactam sodium typically demonstrates inhibitory effects at IC50 values ranging approximately from 5 to 25 g/mL depending upon specific experimental conditions
