Nile Red nucleoside: novel nucleoside analog with a fluorophore replacing the DNA base.
A solvatochromic dye is very useful in studies of local polarity and dynamics in biological systems. A novel solvatochromic chromophore, Nile Red beta-C-2'-deoxyriboside, has been synthesized to act as a photophysical probe, and incorporated site-selectively into an oligodeoxynucleotide. The absorption and fluorescence spectra of Nile Red nucleoside showed a remarkable sensitivity to the solvent polarity.
