Table 2 Summary of compound-induced unwinding of the SC I conformation of pUC19

From: The interactions of novel mononuclear platinum-based complexes with DNA

Compound DNA unwinding angle (°) Drug concentration at coalescence point (μM)α rb(c) (drug: nucleotide at coalescence point)
Cisplatin 13 2.5 ± 0.0 1.0 × 10− 1 ± 2.0 × 10− 3
[Pt(RR-DACH)Cl2] 15.5 ± 1.9 2.2 ± 0.3 8.7 × 10− 2 ± 1.1 × 10− 2
[Pt(RR-DACP)Cl2] 16.9 ± 0.0 1.9 ± 0.0 7.8 × 10− 2 ± 2.0 × 10− 4
[Pt(SS-DACP)Cl2] 13.8 ± 0.6 2.4 ± 0.1 9.5 × 10− 2 ± 4.0 × 10− 3
[Pt(4FH)Cl2] 0.2 ± 0.0 184.5 ± 34.2 7.4 ± 1.4
  1. αThe drug concentration at the coalescence point indicates when the OC plasmid migrates at the same position as the SC I form. The rb (c) values represent the drug to nucleotide ratio at the coalescence point. For all experiments, the amount of nucleotide sample incubated with each compound was 1 × 10− 9 mol. All values in the table were averaged from three separate experiments and are shown with their respective SEM values
