  • Potent anticancer compound.
  • Cell permeable potent DNA topoisomerase I (Topo I) complex inhibitor.
  • Potent apoptosis inducer.
  • Binds reversibly to the DNA topoisomerase I complex, inhibiting the reassociation of DNA after cleavage by topoisomerase I and traps the enzyme in a covalent linkage with DNA. The enzyme complex is ubiquinated and destroyed by the 26S proteasome, consequently depleting cellular topoisomerase I.
  • Prevents DNA re-ligation and therefore causes DNA damage which results in apoptosis.
  • Inhibits mitochondrial topoisomerase I (mtTop1).
  • Blocks the cell cycle at low dose and induces apoptosis in a large number of normal and tumor cell lines by cell cycle-dependent and cell cycle-independent processes.
  • Antiprotozoal and antimalarial compound.
  • Inhibitor of HIV replication and of other viruses.
  • Suppresses nitric oxide (NO) biosynthesis.
  • Shown to suppress TNF-α-induced expression of the inflammasome and cyclooxygenase 2 (COX-2).
