Bacterial proteins and cutaneous biomolecules

Bacterial proteins and cutaneous biomolecules represent a broad category of molecular targets for oxidizing antimicrobial agents, most notably in the treatment of acne vulgaris. This target group includes essential proteins within bacteria such as Cutibacterium acnes and various lipids and proteins found within the human skin's stratum corneum and sebaceous glands (StatPearls: Benzoyl Peroxide, 2023). The therapeutic utility of targeting these molecules lies in the induction of radical-mediated oxidation, which non-specifically disrupts bacterial cell membranes and metabolic enzymes, thereby reducing microbial load and associated inflammation (PubChem: CID 2334). Drugs like benzoyl peroxide act by decomposing to release reactive oxygen species (ROS), which then react with these biomolecules to cause lethal oxidative damage to the pathogens (DrugBank: DB00302). While effective as an antimicrobial strategy, the non-specific nature of this interaction can also lead to the oxidation of host cutaneous biomolecules, resulting in common side effects like skin dryness, erythema, and irritation.
