A40926 is a glycopeptide antibiotic that targets the bacterial cell wall peptidoglycan precursor D-alanyl-D-alanine (D-Ala-D-Ala). It functions by irreversibly inhibiting cell wall synthesis through competitive binding, demonstrating significant bactericidal activity against Gram-positive bacteria, including Staphylococcus and Streptococcus, as well as Neisseria gonorrhoeae, with MIC values ranging from 0.06 to 2 μg/mL. Additionally, A40926 is effective against penicillin-resistant strains, disrupting peptidoglycan cross-linking and leading to bacterial lysis and death. The compound's fat-soluble fatty acid structure enhances serum concentrations and extends its duration of action, with a terminal half-life of 61.22 hours in rats.
