Same mode of action as other beta-lactam antibiotics: disrupt the synthesis of the peptidoglycan layer of bacterial cell walls. Ceftobiprole: Zeftera: Used to treat MRSA (methicillin-resistant Staphylococcus aureus), penicillin-resistant Streptococcus pneumoniae, Pseudomonas aeruginosa, and enterococci: Gastrointestinal upset and diarrhea
The cell wall of both gram-positive and gram-negative bacteria is a tight covalently bound and cross-linked peptidoglycan network and essential for bacterial growth, cell division and cellular structure. Therefore, bacteria need enzymes that can cleave the cell wall during bacterial growth and cell division. The cell wall of bacteria is built ...
As a response to the use of β-lactams to control bacterial infections, some bacteria have evolved penicillin binding proteins with novel structures. β-Lactam antibiotics cannot bind as effectively to these altered PBPs, and, as a result, the β-lactams are less effective at disrupting cell wall synthesis.
This is a list of common β-lactam antibiotics—both administered drugs and those not in clinical use—organized by structural class. Antibiotics are listed alphabetically within their class or subclass by their nonproprietary name. If an antibiotic is a combination drug, both ingredients will be listed.
Cephamycins are a group of β-lactam antibiotics. They are very similar to cephalosporins, and the cephamycins are sometimes classified as cephalosporins. Like cephalosporins, cephamycins are based upon the cephem nucleus. Unlike most cephalosporins, cephamycins are a very efficient antibiotic against anaerobic microbes. [citation needed]
The β-lactam ring is part of the core structure of several antibiotic families, the principal ones being the penicillins, cephalosporins, carbapenems, and monobactams, which are, therefore, also called β-lactam antibiotics. Nearly all of these antibiotics work by inhibiting bacterial cell wall biosynthesis.
Ceftolozane is a type of antibiotic called a cephalosporin, which belongs to the wider group of antibiotics called beta-lactams. [5] It works by interfering with the production of molecules that bacteria need to build their protective cell walls. [5]
Bacitracin is a polypeptide antibiotic derived from a bacterium, Bacillus subtilis, and acts against bacteria through the inhibition of cell wall synthesis. [6] It does this by inhibiting the removal of phosphate from lipid compounds, thus deactivating its function to transport peptidoglycan; the main component of bacterial cell membranes, to the microbial cell wall.
