Cellular DNA and membranes

Cellular DNA and membranes refer to the fundamental molecular structures that constitute the genetic blueprint and the physical boundaries of a cell, respectively. These components are critical therapeutic targets; DNA is primarily targeted in cancer therapy by agents like cisplatin and doxorubicin that induce structural damage to halt cell division [4, 7]. Biological membranes are targeted by antimicrobial agents, such as daptomycin or amphotericin B, which disrupt ionic gradients or physical stability to induce cell death. These structures are also the primary sites of collateral damage from oxidative stress and radiation, which has led to the development of cytoprotective agents like amifostine designed to shield them in healthy tissues [8, 10]. Because DNA and membranes are ubiquitous across all cell types, pharmacological interventions targeting them often face challenges related to systemic toxicity, genotoxicity, and a lack of high specificity for diseased versus healthy tissue [8, 10].

Drugs targeting these components act through DNA alkylation, intercalation, or strand breakage to inhibit replication, or by disrupting membrane integrity through pore formation and depolarization.
