Design of a nonnatural deoxyribonucleoside for recognition of GC base pairs by oligonucleotide-directed triple helix formation

The deoxyribonucleoside 1-(2-deoxy-β-D-ribofuranosyl)-3-methyl-5-amino-1H-pyrazolo[4,3-d]pyrimidin- 7-one (P1) was designed such that two specific hydrogen bonds would form with guanine (G) of a Watson-Crick guanine-cytosine (GC) base pair in the major gr
