Naphthalene-based environmentally sensitive fluorescent 8-substituted 2′-deoxyadenosines: Application to DNA detection
摘要:
We synthesized various C8-naphthylethynylated 2'-deoxyadenosine derivatives and investigated their photophysical properties. Among them, cyano- and N,N-dimethylamino-substituted 8-naphthylethynylated 2'-deoxyadenosine derivatives ((cn)A and (dn)A) showed strong fluorescence with high quantum yields and a remarkable solvatofuorochromicity. In particular, fluorescence of N,N-dimethylamino-substituted (2,6dn)A was not quenched by neighboring guanines (Gs) when incorporated in DNA duplexes, in contrast to (cn)A. We developed a new fluorescent probe containing (2,6dn)A that can be used for the detection of target DNA via a bulge formation regardless of the neighboring sequences. (c) 2012 Elsevier Ltd.

Design and synthesis of environmentally sensitive fluorescent 2-naphthylethynylated 2′-deoxyadenosines: Detection of target DNA via changes in fluorescence intensity and wavelength
Various C2-naphthylethynylated 2'-deoxyadenosines were synthesized as environmentally sensitive fluorescent (ESF) nucleosides and their photophysical properties were examined. Among the ESF nucleosides synthesized, four exhibited strong solvatochromicity, two of which were incorporated into oligodeoxynucleotides (ODNs). These ODN probes were able to detect target DNA through distinct changes in fluorescence intensity and wavelength and acted as effective reporter probes. (C) 2015 Elsevier Ltd. All rights reserved.
