Abstract

We have synthesized various substituted 8-arylethynylated 2′-deoxyguanosine derivatives. Among them, acetyl substituted deoxyguanosine analogue 4c showed a remarkable solvent dependent fluorescence property, that is, an intense fluorescence in non-polar solvents but extremely weak fluorescence in polar solvents like methanol. By using solvatofluorochromic deoxyguanosine analogue 4c, we have developed highly thymine (T) selective fluorescent DNA probes that can sense T opposite 4c in a target DNA regardless of the flanking sequences. We were able to demonstrate that 4c can be used as a T specific base-discriminating fluorescent (BDF) nucleoside in homogeneous fluorescence assay.
