Cellular biomolecules (non-specific)

Cellular biomolecules (non-specific) refers to a broad classification of biological components, including proteins, lipids, and nucleic acids, that are affected by chemical agents without high molecular selectivity. Unlike targeted therapies that interact with specific binding pockets of a single receptor or enzyme, agents acting on non-specific biomolecules typically induce widespread chemical changes such as alkylation, cross-linking, or oxidative damage [1]. This category is most relevant in the context of traditional cytotoxic chemotherapy, such as alkylating agents that damage DNA throughout the genome to arrest cell division, and antiseptics that denature a wide array of microbial proteins and membranes [2][3]. In drug development, non-specific interaction is often associated with high toxicity and a narrow therapeutic window because the drug cannot distinguish between pathological and healthy cellular environments [4]. Consequently, while these interactions are therapeutically exploited in oncology and sterilization, they represent a significant challenge for safety and precision medicine [5].
