Bacterial and cellular DNA and protein

Bacterial and cellular DNA and proteins represent the primary macromolecular constituents of life, serving as the storage for genetic information and the machinery for cellular processes (Nature Education, 2014). DNA serves as a therapeutic target for various classes of drugs, including alkylating agents like cyclophosphamide and platinum-based compounds like cisplatin (StatPearls, 2023). These agents form covalent adducts or cross-links that inhibit DNA replication and transcription, ultimately triggering programmed cell death (PubMed, 2021). Proteins are targeted by a vast array of specific inhibitors, but in the context of broad 'cellular proteins,' they are often the subject of non-specific denaturation or cross-linking by chemical disinfectants such as glutaraldehyde (CDC, 2008). Such broad-spectrum targeting is commonly employed in antimicrobial strategies to ensure the complete inactivation of pathogens (NIH, 2022). However, because this 'target' encompasses nearly all functional molecules within a cell, drugs acting upon it often suffer from significant toxicity and a narrow therapeutic window. The lack of specificity between pathogen and host or between cancerous and healthy cells leads to severe side effects like mutagenicity and organ damage (PubChem, 2023). Consequently, modern drug discovery typically focuses on specific enzymes or receptors rather than the broad categories of DNA or proteins as a whole.
