| Description | Campathecin is a potent DNA enzyme topoisomerase I inhibitor, with an IC50 of 679 nM. |

Topoisomerase I:679 nM (IC50) |
| In Vitro | [3H]BrCPT labeling of topoisomerase I is enhanced greatly by the presence of DNA; very little labeling of isolated topoisomerase I or isolated DNA occurrs. Even in the presence of DNA, [3H]BrCPT labeling of topoisomerase I is inhibited by camptothecin, suggesting that both CPT and BrCPT bind to the same site on the DNA-topoisomerase I binary complex[1]. With increasing concentrations of camptothecin, closed circular pRR322 DNA (form I) is converted to nicked circular DNA (form 11). This apparent nicking activitv of camptothecin required DNA topoisomerase I[2]. |
| Kinase Assay | Each reaction mixture (200 μL, total volume) contained 2 μg of supercoiled pDPT2789 DNA (2.4 nM plasmid concentration), 50 mM Tris-HCl, pH 7.5, 120 mM KCl, 10 mM MgCl2, 0.5 mM EDTA, 0.05% dimethyl sulfoxide, 1% methanol, 100 μg/mL BSA, 4.3 ng of calf thymus topoisomerase I (0.26 nM), and a CPT derivative. The reaction mixture is incubated at 37°C, and at the indicated times 20-μL aliquots are removed and terminated by the addition of 5 μL of SDS/Ficoll stop mix (final concentrations, 0.5% SDS, 2% Ficoll, 0.025% bromphenol blue). The samples are loaded onto a 1% agarose gel and analyzed by electrophoresis. |
