Antibacterial Agent 19（Cat No.:I044598）is a synthetic small molecule developed to combat drug-resistant bacterial infections by targeting bacterial DNA replication or cell wall synthesis pathways. It exhibits potent activity against a broad spectrum of Gram-positive and Gram-negative bacteria, including multidrug-resistant strains such as MRSA and Pseudomonas aeruginosa. Antibacterial Agent 19 has demonstrated favorable pharmacokinetic properties and low cytotoxicity in preclinical studies, making it a promising candidate for therapeutic development. Its mechanism of action and structural specificity also make it valuable for probing bacterial resistance mechanisms and guiding antibiotic discovery efforts.
