Cefmenoxime hydrochloride

Cefmenoxime hydrochloride (CAS No.: 75738-58-8) is a semi synthetic cephalosporin antibacterial research compound in the beta lactam class that is widely used as a reference agent in microbiology, infection biology, and anti infective discovery workflows, with a biological activity profile characterized by broad inhibition of gram positive and gram negative bacteria, including strong activity against Enterobacteriaceae, and a mechanism centered on covalent acylation of bacterial penicillin binding proteins to disrupt the terminal transpeptidation step of peptidoglycan biosynthesis, thereby compromising cell wall integrity and promoting bactericidal effects; functionally, its beta lactamase stability relative to earlier cephalosporins supports its utility for studying resistance phenotypes and structure activity relationships in strains expressing hydrolytic enzymes, while pathway level interpretation typically maps to bacterial cell wall assembly networks and envelope stress responses rather than host signaling pathways, and published research usage generally reports potency in susceptibility platforms within nanomolar to micromolar or low microgram per milliliter ranges depending on organism, inoculum, and assay format, with routine deployment in broth microdilution, time kill, checkerboard combination testing, resistance selection experiments, and translational pharmacology models where concentrations or doses used in experiments typically depend on specific experimental designs and research objectives.
