Abstract:
:The DNA binding characteristics of a mono-, di- and trimeric derivative of 9-aminoacridine were studied. The length of the linking carboxamidoalkyl chains was selected to allow bis- or tris-intercalation according to the excluded-site model. Measurements of DNA unwinding angle using closed circular DNA showed that the trimeric derivative behaves as a tris-intercalating agent. Nevertheless the increase of DNA binding affinity on going from dimer to trimer was found to be relatively small. This is probably related to the large structural constraint for DNA binding of the trimeric derivative. The nature of the linking chain for the design of high-affinity DNA poly-intercalating agents appears therefore critical.
