[structure: see text] Oligonucleotides with a novel, 2'-O-[2-(guanidinium)ethyl] (2'-O-GE) modification have been synthesized, using a novel protecting group strategy for the guanidinium group. This, modification enhances the binding affinity of oligonucleotides to RNA as, well as duplex DNA (DeltaT(m) 3.2 degrees C per modification). The 2'-O-GE, modified oligonucleotides exhibited exceptional resistance to nuclease, degradation. The crystal structure of a palindromic duplex formed by a DNA, oligonucleotide with a single 2'-O-GE modification was solved at 1.16 A, resolution.
