9-Amino Camptothecin Description
9-Amino-20-(R,S)-camptothecin (also known as 9-amino campthecin) is an analogue of camptothecin. Like other CPT congeners, it shows some promising activity against a range of tumor types. This compound causes cell toxicity by stabilizing a ternary complex between the nuclear enzyme topoisomerase I (topo I) and double-stranded DNA, leading to single and double strand breaks. TopoGEN provides this reagent as a control poison/inhibitor of topoisomerase I. For in vitro cleavage detection, we recommend that the drug be tested over a wide range of uM concentrations; however, cleavages are strongly influenced by the amount of topoisomerase in the reaction as well as the type of assay being employed (SDSK+ vs. Radioactive End Labeled DNA vs. testing for plasmid cleavages). Note that large amounts of enzyme will be required to detect cleavage complex, compared to assays that measure catalytic activity.
Molecular Formula: C20H17N3O4
Molecular Weight: 363.37
The drug is supplied already suspended in DMSO at 10 mM (0.25 ml) and is ready for use. The drug is pre-tested and shown to induce topo cleavages using purified human topoisomerase from TopoGEN.
