A 3-fluoro-6-methylaniline nucleoside was synthesized and incorporated
into an oligonucleotide, and its ability to form mercury-mediated base
pairs was studied. UV melting experiments revealed increased duplex
stability with thymine, guanine, and cytosine opposite to the probe and a
clear nucleobase-specific binding preference (T > G > C > A).
Moreover, the 3-fluoro group was utilized as a spin label that showed
distinct 19F NMR resonance shifts depending on the
complementary nucleobase, providing more detailed information on
Hg(II)-mediated base pairing.
