Topotecan is a semi-synthetic derivative of camptothecin and anti-tumor drug that targets topo I. As a topo I poison it induces cleavage complexes.
Irinotecan (CPT-11) is a water soluble, semi-synthetic analogue of 20(S) camptothecin (CPT) with promising activity against a range of tumor types.
Rubitecan (9-nitro-CPT) is a control poison/inhibitor of topo I with promising activity against a range of tumor types.
10-Hydroxy Camptothecin is a control poison/inhibitor of topo I with promising activity against a range of tumor types.
9-Amino Camptothecin is an analog of camptothecin showing promising activity against a range of tumor types. It is provided as a control poison/inhibitor of topo I.
Camptothecin is a topo I poison that both inhibits enzyme activity and stabilizes formation of topo I cleavage complexes.
Etoposide (VP16) is a control poison/inhibitor of topo II. It is also included in the topo II drug screening kit.
Ciproflaxin is a control poison/inhibitor of DNA Gyrase and Topo IV. This is also included in the Topo IV Drug Screening Kit.
Genistein is an isoflavone and inhibitor of tyrosine protein kinases reported to induce topo II dependent cleavages.
