Used primarily in cancer research and therapy, this compound functions as a topoisomerase I inhibitor, disrupting DNA replication in tumor cells. It serves as a precursor or active form in the development of chemotherapeutic agents targeting solid tumors, including colorectal, ovarian, and lung cancers. Its derivatives are explored for improved solubility and reduced toxicity while maintaining potent antitumor activity. Also investigated for use in drug delivery systems such as liposomes or nanoparticles to enhance tumor targeting and bioavailability.
