NCIt definition : A benzopyridoindole derivative with antineoplastic property. Intoplicine inhibits
activities of both topoisomerase I and II via intercalating DNA helix, thereby hindering
the movements of enzymes along DNA molecules during DNA transcription and replication,
respectively. Furthermore, this agent stabilizes DNA-enzyme complexes during unwinding
processes by both topoisomerases, leading to double- and single-stranded DNA breaks.
Consequently, these effects bring about cell growth inhibition and apoptosis of tumor
cells.;
Alternative definition : NCI-GLOSS: A substance that has been studied in the treatment of some types of cancer.
Intoplicine blocks certain enzymes needed for cell division and DNA repair, and it
may kill cancer cells. It is a type of topoisomerase inhibitor.;
