Selective Recognition Of Quadruplex Dna By Small Molecules, Elizabeth W. White
Chemistry Dissertations
Structure-specific recognition of nucleic acids is a promising method to reduce the size of the recognition unit required to achieve the necessary selectivity and binding affinity for small molecules. It has been demonstrated recently that G-quadruplex DNA structures can be targeted by organic cations in a structure-specific manner. Structural targets of quadruplexes include the planar end surfaces of the G-tetrad stacked columns as well as four grooves. The significant structural differences between quadruplex DNA and duplex DNA make quadruplex DNA a very attractive target for highly selective, structure-specific drug design. We have used a variety of biophysical techniques including circular …
