TG4104
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…

TG4120
TopoGEN provides this reagent as a control poison/inhibitor of topoisomerase II.  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…

TG4200
HU-331 is a cannabinoid-based quinone with potential anticancer activity.  It has anti-topo IIa activity as a catalytic inhibitor rather than a poison (such as etoposide).    
TG2003H
Tyrosyl-DNA phosphodiesterase-2  (TDP2) functions to remove trapped topoisomerase II/DNA complexes by processing 5′- blocking protein (topo II) at the site of the DNA break (Fig 1). In terms of physiological relevance, there appear to be multiple roles for TDP2, well beyond the repair of type II topoisomerase damage and subsequent…

Tyrosyl-DNA phosphodiesterase-2  (TDP2) functions to remove trapped topoisomerase II/DNA complexes by processing 5′- blocking protein (topo II) at the site of the DNA break (Fig 1).  Assaying this activity can be difficult, requiring labeled oligos and isotopes or complicated detections that are hard to set up.  In many…
