Novel Fluoroindenoisoquinoline Non-Camptothecin Topoisomerase I Inhibitors [PDF]
Abstract Contrary to other anticancer targets, topoisomerase I (TOP1) is targeted by only one chemical class of FDA-approved drugs: topotecan and irinotecan, the derivatives of the plant alkaloid, camptothecin. The indenoisoquinolines LMP400, LMP744, and LMP776 are novel noncamptothecin TOP1 inhibitors in clinical trial, which ...

Dual-acting histone deacetylase-topoisomerase I inhibitors [PDF]
Current chemotherapy regimens are comprised mostly of single-target drugs which are often plagued by toxic side effects and resistance development. A pharmacological strategy for circumventing these drawbacks could involve designing multivalent ligands that can modulate multiple targets while avoiding the toxicity of a single-targeted agent.

Discovery of DNA Topoisomerase I Inhibitors with Low-Cytotoxicity Based on Virtual Screening from Natural Products [PDF]
Currently, DNA topoisomerase I (Topo I) inhibitors constitute a family of antitumor agents with demonstrated clinical effects on human malignancies. However, the clinical uses of these agents have been greatly limited due to their severe toxic effects ...

Small DNA circles as bacterial topoisomerase I inhibitors [PDF]
It is demonstrated that small DNA circles showed high inhibitory effect on the activity of bacterial topoisomerase I and the single-stranded regions associated with bending deformation are believed to be the crucial factor for trapping the enzymes.
