Optimization of triple-helix-directed DNA cleavage by benzoquinoquinoxaline-ethylenediaminetetraacetic acid conjugates.

Abstract

The formation of triple-helical structures of DNA is based on sequence-specific recognition of oligopyrimidine.oligopurine stretches of double-helical DNA. Triple-helical structures can be stabilized by DNA-binding ligands. Benzoquinoquinoxaline (BQQ) derivatives are among the most potent intercalating-type agents known to stabilize DNA triple-helical… (More)
