Microbial cellular components (Non-specific oxidative damage)

Microbial cellular components subject to non-specific oxidative damage serve as the primary target for a variety of broad-spectrum antiseptic and disinfectant agents [StatPearls, 2023]. These targets encompass a wide array of essential biomolecules, including membrane lipids, transport proteins, metabolic enzymes, and genomic material [DrugBank, 2024]. Oxidizing agents, such as hydrogen peroxide and benzoyl peroxide, exert their antimicrobial effects by generating reactive oxygen species (ROS) or through direct chemical oxidation of thiol groups and unsaturated fatty acids [PubMed, 2021]. This indiscriminate attack leads to the rapid loss of membrane integrity, denaturation of proteins, and fragmentation of DNA, effectively neutralizing bacteria, viruses, and fungi [NIH, 2022]. Because these agents hit multiple vital components simultaneously, the development of microbial resistance is significantly hindered compared to site-specific antibiotics [Microbiology Society, 2020]. However, the non-selective nature of this mechanism also poses risks to host tissues, often resulting in localized cytotoxicity or irritation, which restricts their therapeutic application primarily to topical or environmental use [PubChem, 2024].
