The present invention relates to naphthalene diimides, NDIs, and methods of synthesising them. The NDIs have DNA-quadruplex binding and stabilising activity, and potential in treatment of pancreatic, prostate, and other human cancers. The NDIs are a compound of Formula I:

The synthesis together with biophysical and biological evaluation of a series of tetra-substituted naphthalene diimide (ND) compounds, are presented. These compounds are positional isomers of a recently-described series of quadruplex-binding ND derivatives, in which the two N-methyl-piperidine-alkyl side-chains have now been interchanged with the positions of side-chains bearing a range of end-groups. Molecular dynamics simulations of a pair of positional isomers are in accord with the quadruplex stabilization and biological data for these compounds. Analysis of structure-activity data indicates that for compounds where the side-chains are not of equivalent length then the positional isomers described here tend to have improved cell proliferation potency and in some instances, superior quadruplex stabilization ability.
