NCIt definition : 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, cositecan
exhibits enhanced tissue penetration and bio-availability compared to water-soluble
camptothecins.;
