Large Stabilization of a DNA Duplex by the Deoxyadenosine Derivatives Tethering an Aromatic Hydrocarbon Group
摘要:
Novel deoxyadenosine derivatives tethering a phenyl or naphthyl group by means of an amido linker have been synthesized, and these derivatives, stacking on the 5' end of a DNA duplex, provide free energy contributions equal to or greater than that of the Watson-Crick A/T base pair.

6-(Nâ²-Arylcarbamoyl)-2â²-deoxyadenosine-H-phosphonates displayed molecular recognition towards cationic phenothiazinium and phenoxazinium dyes in aqueous solutions; studies have shown that binding is driven mainly by aromatic interactions and that size and shape-complementarity of the aromatic rings in host and guest provides selectivity.
