Microbial membrane and protein targets

Microbial membrane and protein targets represent a broad set of essential components within bacteria, fungi, viruses, and protozoa that are targeted by non-specific antimicrobial agents, particularly antiseptics and disinfectants (McDonnell & Russell, 1999). These targets include the lipid bilayer of the cell membrane, which maintains structural integrity and electrochemical gradients, as well as a wide array of functional proteins such as enzymes and transport proteins. Unlike targeted antibiotics that inhibit specific metabolic pathways, agents hitting these targets often cause rapid, widespread damage through oxidation, denaturation, or disruption of membrane permeability (Bigliardi et al., 2017). This multi-target approach is highly effective at preventing the development of resistance and provides broad-spectrum activity against a diverse range of pathogens. Commonly used drugs that interact with these targets include povidone-iodine, which halogenates proteins and lipids, and chlorhexidine, which disrupts the cytoplasmic membrane. In clinical practice, these targets are primarily exploited for topical antisepsis, wound care, and surface disinfection to reduce the risk of infection (StatPearls, 2023).
