Structure of the first parallel DNA quadruplex-drug complex. Clark, G. R, Pytel, P. D, Squire, C. J, & Neidle, S. Journal of the American Chemical Society, 125(14):4066–7, May, 2003. ISBN: 1236712374
Paper doi abstract bibtex The first crystal structure of a drug (daunomycin) bound to a parallel-stranded intermolecular telomeric G4 quadruplex (d(TGGGGT)4) has been determined to high resolution. A planar assemblage of three daunomycin molecules stacks onto the 5' end of the G4 column, with the daunosamine substituents occupying three of the four quadruplex grooves. The surface area of the terminal G-quartet in this parallel DNA quadruplex, presently occupied by three daunomycins, is sufficiently large that it could easily accommodate other potential telomerase inhibitors such as substituted porphyrins or telomestatin.
