A drug being studied in the treatment of cancer. It belongs to a family of drugs called topoisomerase inhibitors. It is related to the anticancer drug camptothecin.
A synthetic silicon-containing agent related to camptothecin with antineoplastic properties. Cositecan stabilizes the cleavable complex between topoisomerase I and DNA, resulting in DNA breaks and consequently triggering apoptosis. Because it is lipophilic, karenitecin exhibits enhanced tissue penetration and bio-availability compared to water-soluble camptothecins.
Karenitecin has been defined 3 different ways in documents like Glossary of Cancer Terms, NCI Drug Dictionary, NCI Dictionary of Cancer Terms.
