QUICK LINKS

Rubitecan is a compound that has garnered attention in the field of cancer research due to its potential to interfere with the replication of DNA in rapidly dividing cells. It is a derivative of camptothecin, which is known for its topoisomerase I inhibitory activity, a critical enzyme in DNA replication. Studies involving Rubitecan focus on understanding its mechanism of action, specifically how it stabilizes the complex between topoisomerase I and DNA, leading to DNA damage and cell death. Research also delves into the compound′s ability to induce apoptosis in various cancer cell lines. Additionally, Rubitecan is used in the synthesis of analogs that may possess improved solubility or efficacy.
