Description
Topotecan-d
6 is intended for use as an internal standard for the quantification of topotecan by GC- or LC-MS. Topotecan is an inhibitor of DNA topoisomerase I and a derivative of the DNA topoisomerase I inhibitor camptothecin . Topotecan inhibits DNA topoisomerase I in human MCF-7 breast and DU145 prostate cancer cells with IC
50 values of 13 and 2 nM, respectively, in a cell-based luciferase reporter assay. Topotecan induces cytotoxicity and DNA damage in HT-29 human colon adenocarcinoma cells (IC
50s = 33 and 280 nM, respectively). Formulations containing topotecan have been used in the treatment of small-cell lung cancer.
