Combined nucleobase and backbone modifications enhance DNA duplex stability and preserve biocompatibility

Abstract:

DNA strands containing a triazole linkage flanked on its 3′-side by an aminoethylphenoxazine nucleobase analogue (G-clamp) have been prepared by solid-phase synthesis followed by CuAAC-mediated click oligonucleotide ligation. The stability of the doubly modified DNA duplexes and DNA-RNA hybrids is greatly increased, whereas a single base pair mismatch located at or adjacent to the modifications is strongly destabilising, making triazole G-clamp a potent mismatch/point mutation sensor. A DNA s...
