DNA-binding metallo-intercalators are positively charged, planar, polycyclic, aromatic compounds that unwind the DNA double helix and insert themselves between DNA base pairs. Metallo-intercalators insert themselves between two intact base pairs without expelling or replacing the original nitrogenous bases; the hydrogen bonds between the nitrogenous bases at the site of intercalation remain unbroken. In addition to π-stacking between the aromatic regions of the intercalator and the nitrogenous bases of DNA, intercalation is stabilized by van der Waals, hydrophobic, electrostatic, and entropic interactions. This ability to bind to specific DNA base pairs allows for potential therapeutic applications of metallo-intercalators.
