Structural highlights
Publication Abstract from PubMedThe crystal structure of a complex between the bimolecular human telomeric quadruplex d(TAGGGTTAGGGT)2 and the experimental anticancer drug BRACO-19, has been determined, to 2.5 A resolution. The binding site for the BRACO-19 molecule is at the interface of two parallel-folded quadruplexes, sandwiched between a G-tetrad surface and a TATA tetrad, and held in the site by networks of water molecules. The structure rationalizes the existing structure-activity data and provides a starting-point for the structure-based design of quadruplex-binding ligands Structural basis of DNA quadruplex recognition by an acridine drug.,Campbell NH, Parkinson GN, Reszka AP, Neidle S J Am Chem Soc. 2008 May 28;130(21):6722-4.
