Antibacterial agent 19

Antibacterial agent 19 demonstrates potent in vitro efficacy against K. pneumoniae and methicillin-resistant S. aureus (MRSA) with an MIC of 0.022 mg/mL, and against vancomycin-resistant S. aureus (VRSA) with an MIC of 0.045 mg/mL. This small molecule is a valuable research tool for studying novel antimicrobial mechanisms and resistance in both Gram-positive and Gram-negative pathogens.
