Abstract

Single and multiple incorporations of stereochemically pure modified dinucleoside- phosphoramidates involving substituent groups ending with bis-hydroxyethyl and bis- aminoethyl groups have been performed into pyrimidic triple helix-forming oligo-2′- deoxyribonucleotides designed to bind parallel to the purine strand of the DNA target. The ability of these modified oligo-2′-deoxyribonucleotides to form triple helices has been ...
