Bridged nucleic acid
WebBNAs are a recently developed class of artificial nucleic acid analogs with high affinity to ssRNA, DNA, dsDNA. They contain a five-membered or six-membered bridged structure with a "fixed" C3'-endo sugar puckering. This bridge binds to the 2', 4'-position of the ribose to obtain a 2', 4'-BNA monomer. WebAbstract. 2′-O,4′-C-Ethylene-bridged nucleic acid (ENA) phosphoramidites are highly promising modified nucleic acid monomers discovered by Daiichi Sankyo. To increase the productivity of manufacturing, we have developed a highly efficient synthetic method for …
