Typically, 0.24 μg of supercoiled pUC19 plasmid DNA (Bayou Biolabs, Harahan, LA) was incubated with 5 U of human topoisomerase I enzyme (TopoGEN Inc., Port Orange, FL) for 5 min at 37 °C in 1× Topo I reaction buffer. The appropriate amount of compound was then added and the reaction mixture incubated for a further 1 hr at 37 °C. The reaction was terminated using 0.5% SDS and 0.5 mg/mL proteinase K. Subsequent incubation for an additional 15 min was followed by enzyme and compound extraction using a mixture of phenol/chloroform/isoamyl alcohol (25:24:1). The remaining DNA sample was then run on an agarose gel (1%) at 75 V for 3 h, stained with ethidium bromide, and photographed (type 667 film).

-6 M in bp, 1.4 mL) over 24 s at 300 s intervals using a 250 μL syringe rotating at 290 rpm. Samples were degassed at 20 °C using a ThermoVac apparatus (MicroCal) before use. Each peak corresponded to the decrease in the power supplied to keep the temperatures of the sample and reference cells the same for each injection and represents the heat given off. In each case, response signals were corrected for the small heat of dilution associated with titrating the drug into the buffer. The heat of dilution for titrating buffer into DNA was found to be negligible. The heat released on binding was directly proportional to the amount of binding. A binding isotherm of heat released versus the molar ratio was constructed and the data fitted by non-linear least square fitting analysis to a model based on a single set of identical binding sites.

m) studies were conducted on a Varian Cary 100 Bio UV-visible spectrophotometer attached to a temperature controller. Experiments were performed in 20 mM sodium phosphate buffer, pH 7.0. Melting profiles were obtained by measuring the absorbance at 260 nm as a function of temperature (25-95 °C) at a ramp rate of 0.5 °C/min. The concentration of DNA (calf thymus) was generally 10 μM (bp) with a DNA/drug ratio of 3:1.

Experimental partition coefficient (log P) for each NDI compound was determined by the Shake-flask method by preparing a saturated solution in water, followed by thorough mixing with an equal volume of n-octanol. The mixture was then allowed to partition and equilibrate overnight. Subsequent spectrophotometric determination of the relative NDI concentration in n-octanol versus water layers yielded the n-octanol/water log P.
