Triplex-mediated recognition of Py.Pu base pairs in DNA is a greater challenge than for Pu.Py base pairs as fewer hydrogen bonds are presented for binding in the major groove. Initial studies on m-aminophenyl-modified analogues of the bicyclic nucleoside N-methyl-3H-pyrrolo[2,3-d]pyrimidin-2(7 H)-one suggest that selective recognition of the CG base pair is possible.
