To identify novel Tdp1 inhibitors, we developed a high-throughput assay that uses electrochemiluminescent (ECL) substrates. Subsequent to screening of 1981 compounds from the 'diversity set' of the NCI-Developmental Therapeutics Program, here we report that furamidine inhibits Tdp1 at low micromolar concentrations. Inhibition of Tdp1 by furamidine is effective both with single- and double-stranded substrates but is slightly stronger with the duplex DNA. Surface plasmon resonance studies show that furamidine binds both single- and double-stranded DNA, though more weakly with the single-stranded substrate DNA. Thus, the inhibition of Tdp1 activity could in part be due to the binding of furamidine to DNA. However, the inhibition of Tdp1 by furamidine is independent of the substrate DNA sequence. The kinetics of Tdp1 inhibition by furamidine was influenced by the drug to enzyme ratio and duration of the reaction. Comparison with related dications shows that furamidine inhibits Tdp1 more effectively than berenil, while pentamidine was inactive. Thus, furamidine represents the most potent Tdp1 inhibitor reported to date."xsd:string |
