Abstract
The HSP90 protein is an important target in cancer. We report here that stable quadruplex DNAs can be formed from a promoter sequence in the HSP90 gene, on the basis of melting, circular and NMR studies, and show that these can be selectively targeted by non-macrocyclic quadruplex-stabilizing phenyl bis-oxazole derivatives. These do not bind significantly to duplex DNA and show low stabilization of the human telomeric quadruplex. These results suggest an approach to targeting HSP90 at the DNA level.
