Beta-lactam Antibiotics

β-lactam antibiotics are characterized by four-membered ß-lactam ring. Penicillin G was the first β-lactam antibiotic that entered the clinic. Almost all ß-lactam antibiotics derived initially from microbes through a fermentation process. β-lactam antibiotics are bactericidal, and act by inhibiting the synthesis of the peptidoglycan layer of bacterial cell walls. The activity of these antibiotics is related to the opening of the ß-lactam ring. These antibiotics have broad antibacterial spectrum, strong antibacterial activity, low toxicity, high industrial level, clear structure-activity relationship, and high alterability, so they have been widely developed and applied.

    Isosulfazecin 77900-75-5
    Isosulfazecin (iSZ) is a novel β-lactam antibiotic produced by Pseudomonas acidophilus sp., synthesized in a nutrient solution supplemented with glycerol and sodium thiosulfate under aerobic conditions in parallel with bacterial growth. It is purified by chromatography and crystallization from aqueous methanol. Physicochemical analysis determined its molecular formula to be C12H20N4O9S, showing a structure with a β-lactam ring, methoxyl and sulfonate groups. Acid hydrolysis yields L-alanine and D-glutamic acid. iSZ is a diastereomer of sulfadiazine and exhibits moderate activity against both gram-positive and gram-negative bacteria, but potent activity against bacteria resistant to β-lactam antibiotics.
