Both ITC and CD spectroscopy data indicate that the abietane diterpenes of this study exhibit strong binding to DNA, likely preferring a DNA-groove binding mode. Binding constants (<em>K</em>) were found to be in the order of 10<sup>6–8</sup> M<sup>−1</sup> and were strongly enthalpically driven. The binding of all compounds to DNA was accompanied by large negative enthalpy changes (more than −20 kcal/mol) and negative entropy changes.

This is significant given the reports that the identity of the substituent at position-7 is a strong determinant for bioactivity. Although the specific CD data observed was compound-dependent, most showed strong signal perturbations around one or both of the DNA signature wavelengths (245 and 280 nm). However, we do not attribute these perturbations to DNA intercalation.
