Intracellular cytoskeletal or DNA target

Intracellular cytoskeletal or DNA target is a broad pharmacological classification encompassing structural proteins and nucleic acids essential for cellular integrity and replication. The cytoskeletal component primarily involves tubulin, which forms microtubules necessary for the mitotic spindle; drugs such as taxanes (e.g., paclitaxel) and vinca alkaloids (e.g., vincristine) target these to arrest the cell cycle (StatPearls, "Antineoplastic Agents"). DNA targets include the double helix itself or enzymes like topoisomerases and DNA polymerases; agents such as cisplatin or doxorubicin induce DNA damage or inhibit repair, leading to apoptosis (NIH, National Cancer Institute). These targets are fundamental to the mechanism of action of many traditional chemotherapeutic agents used in oncology (Alberts et al., "Molecular Biology of the Cell"). Because this term aggregates multiple distinct molecular systems, it is categorized as a functional group rather than a single specific therapeutic target.
