Various proteins and DNA

The term Various proteins and DNA is a non-specific descriptor rather than a distinct, valid therapeutic target. It is typically used in pharmacological databases to categorize agents—such as non-selective alkylating agents, cross-linkers, or general antiseptics—that react indiscriminately with a wide array of cellular macromolecules (National Cancer Institute, 2024). Because this designation encompasses a vast and heterogeneous group of molecules, it lacks the specificity required for modern targeted therapy and precision medicine (Nature Reviews Drug Discovery, 2023). Drugs associated with this broad interaction profile, such as certain classical chemotherapeutics, often work by damaging the structural integrity of DNA or inactivating essential enzymes through covalent modification (StatPearls, 2023). Consequently, these agents are frequently associated with significant systemic toxicity and a narrow therapeutic window due to their lack of selectivity between diseased and healthy cells (PubMed, 2022).
