Used as an experimental antitumor agent, particularly in the treatment of solid tumors such as colon, lung, and liver cancers. It functions by inhibiting topoisomerase I, an enzyme critical for DNA replication and cell division, leading to cancer cell death. Its nitro group enhances stability and may improve tissue penetration, making it a candidate for targeted chemotherapy. Research also explores its potential in drug delivery systems like nanoparticles to increase efficacy and reduce side effects.
