Photoinduced electron transfer (PeT)-based hybridization probe is a linear and quencher-free oligonucleotide (ON) probe for DNA or RNA detection. In this report, we designed and synthesized novel adenosine analogues for PeT-based hybridization probe. In particular, the analogue containing a piperazinomethyl moiety showed effective quenching property under physiological conditions. When the probe containing the analogue was hybridized with a complementary DNA or RNA, the fluorescence increased 3- or 4-fold, respectively, compared to the single-stranded state.
