Abstract

Abstract Triplex forming 3′-protected pyrimidine oligo (2′-O-methylribonucleotides) containing minor groove binders (MGB) and triplex specific intercalator, benzoindoloquinoline (BIQ), at the 5′-terminus were synthesized. The resulting conjugates formed stable complexes with a target dsDNA due to the simultaneous binding to the minor and major grooves and BIQ intercalation. The dissociation constants and the thermal ...
