Sequence selective formation of 1,N6-ethenoadenine in DNA by furan-conjugated probe

1,N6-Ethenoadenosine derivatives have been applied as fluorescence probes in various fields of biochemistry and molecular biology. We developed a 1,N6-ethenoadenosine-forming reaction at a target adenine in DNA duplex and applied it to a mutation diagnosis. Furan-derivatized oligodeoxyribonucleotides were synthesized and fluorescence properties were studied in the presence of complementary strand under oxidative conditions. Strong emissions at 430 nm were observed in the presence of the complementary strand with an adenine in front of furan moiety.
