Inhibition of cell wall synthesis examples
WebbInhibition of cell wall synthesis can be accomplished by two main mechanisms: either by inhibition of enzyme function, for example, by beta-lactam antibiotics targeting the penicillin-binding proteins (PBPs), or by binding and blocking access to essential cell wall precursors such as the ultimate peptidoglycan building block lipid II. WebbInhibitors of Nucleic Acid Synthesis Some antibacterial drugs work by inhibiting nucleic acid synthesis ( Table 14.5 ). For example, metronidazole is a semisynthetic member of the nitroimidazole family that is also an antiprotozoan. It …

Antibiotics that disrupt essential bacterial metabolic pathways are acting as antimetabolites. These chemicals are structurally similar to natural metabolites but just different enough to interfere with normal cell function. For example, trimethoprim inhibits the synthesis of folic acid, a vitamin which ...
WebbIn both Gram-positive and Gram-negative bacteria, the cell wall is formed from a cross-linked chain of alternating units of N -acetylglucosamine and N -acetylmuramic acid, known as peptidoglycan or mucopeptide.
