| - | We find that a hairpin DNA that incorporates the modified base FdU when complexed with the small molecule netropsin and zinc displays increased cytotoxicity towards PC3 prostate cancer cells relatives to their components or separate complexes. In order to investigate the origin of this cytotoxicity, we used NMR spectroscopy, circular dichroism, and semi-empirical quantum mechanical calculations to study and model the new structural motif formed by this complex.
