?-lactam antibiotics (beta-lactam antibiotics) are a class of broad-spectrum antibiotics, consisting of all antibiotic agents that contain a beta-lactam ring in their molecular structures. This includes penicillin derivatives (penams), cephalosporins (cephems), monobactams, and carbapenems. Most ?-lactam antibiotics work by

Figure 49.2 Schematic diagram of a single layer of peptidoglycan from a bacterial cell (e.g. Staphylococcus aureus), showing the site of action of the β-lactam antibiotics. In S. aureus, the peptide crosslinks consist of five glycine residues. Gram-positive bacteria have several layers of peptidoglycan. (NAG

This review attempts to pinpoint the importance of betalactam antibiotics, which encompass penicillins, cephalosporins, cephamycins, carbapenems and monobactams from its chemistry, classification, pharmacokinetics, clinical uses and analysis. ?- lactam antibiotics have been used for treatment of bacterial infections.

28 Mar 2013 ?-Lactam antibiotics are one of the most important antibiotic classes but are plagued by problems of resistance and the development of new ?-lactam antibiotics through side chain modification of existing ?-lactam classes is not keeping pace with resistance development. In this perspective we summarize
Beta-Lactam Antibiotics For Clinical Use is a collection of sixteen chapters covering a broad range of topics on penicil- lins, cephalosporins, and other beta-lactam antibiotics. The chapters are divided into four main sections: “B-Lactam. Antibiotics: General Considerations," “Penicillins," “Cepha- losporins," and “Novel Types
INTRODUCTION. The ?-lactam antibiotics are a large class of diverse compounds used clinically in both the oral and parenteral forms. The ?-lactam antibiotic agents have become the most widely used therapeutic class of antimicrobials because of their broad antibacte- rial spectrum and excellent safety profile. Reports of
The Carbacephems: A New Beta-Lactam. Antibiotic Class. ROBIN D.G. COOPER, D.Sc., Ph.D., Indianapolis, Indiana. The carbacephems are a new class of/]-lactam antibiotics that are similar in structure to the cephalosporins. Carbacephems differ from cephalosporins, however, in the substitution of a sulfur atom in the
