Bacterial cell wall and membrane protein

The term "Multiple bacterial targets including cell wall/membrane proteins" refers to a broad set of bacterial structures that are essential for bacterial survival and pathogenicity and serve as well-established therapeutic targets for antibacterial drugs. The bacterial cell wall—primarily composed of peptidoglycan in both Gram-positive and Gram-negative bacteria—and associated membrane proteins are crucial for maintaining cell structure, protecting against environmental stress, and enabling infection. A variety of antibiotic classes target distinct steps in the assembly and maintenance of the bacterial cell wall (e.g., β-lactams, glycopeptides inhibit peptidoglycan synthesis), or disrupt cell membrane integrity (e.g., polymyxins, lipopeptides), leading to bacterial death. Additional therapeutics, such as monoclonal antibodies, can target virulence-associated cell-surface proteins or neutralize secreted toxins. These targets are absent from human cells, which reduces the risk of mechanism-based toxicity, but misuse of antibiotics rapidly leads to the development of resistance, posing major public health challenges[1][2][3][4].
