TG4110 |
Camptothecin is a topo I poison that both inhibits enzyme activity and stabilizes formation of topo I cleavage complexes (Hsiang et al J. Biol. Chem. 260:14873-14878, 1985). TopoGEN provides this reagent as a control inhibitor/poison of topoisomerase I. For in vitro cleavage detection, we recommend that the drug… Read more (+) Camptothecin is a topo I poison that both inhibits enzyme activity and stabilizes formation of topo I cleavage complexes (Hsiang et al J.

20(S)camptothecin has shown promising activity against a range of tumour types. This CPT derivative 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.
