α-LNA (locked nucleic acid with α-D-configuration): Synthesis and selective parallel recognition of RNA

α-LNA is presented as a stereoisomer of LNA (locked nucleic acid) with α-D-configuration. Three different approaches towards the thymine α-LNA monomer as well as the 5-methylcytosine α-LNA monomer are presented. Different α-LNA sequences have been synthesised and their hybridisation with complementary DNA and RNA has been evaluated by means of thermal stability experiments and circular dichroism spectroscopy. In a mixed pyrimidine sequence, α-LNA displays unprecedented parallel-stranded and selective RNA binding. Furthermore, a remarkable selectivity for hybridisation with RNA over DNA is indicated.

Synthesis and evaluation of α-LNA

Three different synthetic routes to the α-configured LNA thymine monomer starting from D-allose or D-arabinose were investigated. The introduction of one or four α-LNA monomers into α-DNA had a destabilizing effect on the duplexes. However, a fully modifi
