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. ...

Many antibiotics appear to have as their mechanism of action the capacity to inhibit bacterial cell wall synthesis. This does NOT appear to be a mechanism of A. Aminoglycosides B. Penicillins C. Bacitracin D. Cephalosporins E. Vancomycin 相关知识点: 试题来源: 解析 A null 反馈 收藏 ...
In this article, we summarize the mechanisms of important antibiotic families that inhibit cell wall formation (尾-lactams and vancomycin) or disrupt cell membrane (polypeptides) or inhibit fatty acids that form cell membranes. The recent development of novel antibacterial agents that target fatty ...

The cell wall synthesis inhibitors segment dominated the market in 2023. Cell wall synthesis inhibitors are widely used antibiotics, as they are described with wide-spectrum action against gram-positive and gram-negative bacteria. These drugs inhibit the synthesis of the peptidoglycan layer, which is...
