Preferred Label : Topotecan Hydrochloride;
NCIt synonyms : topotecan hydrochloride (oral); Hycamptamine; Topotecan HCl; (S)-10-[(dimethylamino)methyl]-4-ethyl-4,9-dihydroxy-1H-pyrano[3',4':6,7] indolizino[1,2-b]
quinoline-3,14-(4H,12H)-dione Monohydrochloride;
NCIt related terms : Hycamtin;
NCIt definition : The hydrochloride salt of a semisynthetic derivative of camptothecin with antineoplastic
activity. During the S phase of the cell cycle, topotecan selectively stabilizes topoisomerase
I-DNA covalent complexes, inhibiting religation of topoisomerase I-mediated single-strand
DNA breaks and producing potentially lethal double-strand DNA breaks when complexes
are encountered by the DNA replication machinery. Camptothecin is a cytotoxic quinoline-based
alkaloid extracted from the Asian tree Camptotheca acuminata.;
Alternative definition : NCI-GLOSS: A drug used to treat certain types of ovarian cancer, lung cancer, and
cervical cancer. Hycamtin is a type of topoisomerase inhibitor.;
