Аннотация:Novel DNA intercalating anticancer drug curaxin CBL0137 significantly inhibited in vitro DNA methylation by eukaryotic DNA methyltransferase Dnmt3a catalytic domain (Dnmt3a-CD) at low micromolar concentrations (IC50 3 – 9 µM). CBL0137 reduced the binding affinity of Dnmt3a-CD to its DNA target, causing up to four-fold increase in the Kd of the enzyme/DNA complex. Binding of CBL0137 to Dnmt3a-CD was not observed. The observed decrease in methylation activity of Dnmt3a-CD in the presence of CBL0137 can be explained by curaxin’s ability to intercalate into DNA.
