Cellular and microbial biomolecules

Cellular and microbial biomolecules represent a broad category of targets—including proteins, lipids, and nucleic acids—that are susceptible to chemical modification through oxidative reactions. This target profile is typically associated with non-specific antimicrobial agents such as benzoyl peroxide and hydrogen peroxide, which exert their effects by generating reactive oxygen species (ROS) or free radicals (StatPearls, 2023). These reactive species attack critical cellular structures, such as thiol groups in enzymes and double bonds in membrane lipids, leading to protein denaturation and lipid peroxidation (CDC, 2008). The resulting widespread damage disrupts the structural integrity of the microbial cell membrane and halts essential metabolic processes, ultimately causing rapid cell death (NCBI, 2017). While highly effective as broad-spectrum biocides against bacteria, fungi, and viruses, these agents lack specificity and can also cause oxidative damage to healthy host tissues. Consequently, their therapeutic use is primarily restricted to topical applications for conditions like acne or as antiseptics for wound care and surface disinfection.
