Structure of the bacterial cell wall, the metabolic pathway for the biosynthesis of cell wall, and various antibiotics affecting various stages of cell wall synthesis are presented. Mechanisms of action of the antibiotics and the mechanisms of resistance development to the antibiotics are discussed. ...

Inhibitors of Cell Wall Synthesis | Overview & Examples from Chapter 15 / Lesson 5 77K Learn about cell wall synthesis inhibitors. Identify mycobacteria, glycopeptide, beta-lactamase inhibitors, and examine the problem of antibiotic resistance. Related...
These antibiotics function through the inhibition of bacterial cell wall synthesis. Following extensive use, some bacterial populations have shown ability to develop resistance to beta-lactams and become more virulent. Cephalosporins are a members of the ...

complex process that starts with the physical interaction of the molecule and its specific targets and involves biochemical, molecular, and structural changes, acting on multiple cellular targets such as: 1) DNA replication, 2) RNA synthesis, 3) cell wall synthesis, and 4) protein synthesis (Fig...
Drug resistance is still menacing the society with many lives being lost due to deadly infections caused by continuously evolving strains spread beyond our means to eradicate them or prevent their spreading. Herein, the emergence and evolution of antibiotics is briefly reviewed, and a select number...
Nistatin and levorin are prescribed to prevent and treat this disease. Side effects sometimes result from antibiotic therapy. The prolonged administration of large doses of penicillin has a toxic effect on the central nervous system, streptomycin affects the acoustic nerve, and so on. These ...
Similar to but distinct from penicillins, glycopeptides prevent the formation of cross-links in the peptidoglycan cell wall. While penicillinsirreversibly and competitively inhibit DD-transpeptidase, glycopeptides bind to theproteins in the cell wallthemselves to prevent DD-transpeptidase from binding. ...
