Structural and dynamical effects induced by the anticancer drug topotecan on the human topoisomerase I - DNA complex

This research delves into the molecular mechanisms by which topotecan, an anticancer drug belonging to the camptothecin family, exerts its therapeutic effect. The study focuses on the interaction of topotecan with human topoisomerase I, an enzyme crucial for DNA replication, transcription, and chromosomal segregation. The researchers explore the structural and dynamical effects of topotecan on the topoisomerase I-DNA complex, providing insights into its mode of action. The study highlights the critical role of topoisomerase I in fundamental cellular processes, making it a prime target for anticancer drugs. Camptothecins, including topotecan, bind to the covalent intermediate formed between the enzyme and DNA, effectively trapping the complex and inhibiting the religation process. This disruption leads to the formation of lethal double-strand DNA breaks, ultimately triggering cell death.
