Cellular proteins and membrane lipids

Cellular proteins and membrane lipids are the primary structural and functional components of biological cells, with proteins acting as catalysts and receptors while lipids form the essential semi-permeable membranes (Karger, 2025). Although not a specific, single therapeutic target, these macromolecules are the primary sites of damage in oxidative stress-related pathologies, such as neurodegeneration and cardiovascular disease, where reactive oxygen species (ROS) induce lipid peroxidation and protein carbonylation (MDPI, 2020). Therapeutic strategies often involve protecting these components using antioxidants like edaravone or vitamin E to maintain cellular homeostasis (Xavron, 2021). Conversely, certain antimicrobial agents like daptomycin and general antiseptics exert their effects by non-specifically disrupting the integrity of these cellular constituents to induce lysis (RSC, 2017). Furthermore, photodynamic therapy (PDT) leverages the generation of ROS to cause widespread, non-specific damage to these molecules within malignant cells to trigger apoptosis (MDPI, 2020).

Drugs targeting these components typically act through non-specific physical disruption of the lipid bilayer or through the generation/scavenging of reactive oxygen species that chemically modify protein and lipid structures.
