As a pioneer in oligonucleotide synthesis, Creative Peptides has been working on developing new oligonucleotide-based technologies that can produce compounds with excellent binding affinity and chemical/biological stability. Creative Peptides has advanced equipment, advanced technology and experienced staff to help you synthesize bridged nucleic acid (BNA) oligodeoxynucleotides of interest to ensure your satisfaction in a timely and professional manner.
Bridged nucleic acids (BNA) are modified RNA nucleotides, sometimes referred to as restricted or inaccessible RNA molecules. BNA monomers can contain five-membered, six-membered or even seven-membered bridging structures with "fixed" C3'-endo sugar puckering. The chemical structure of the BNA monomer contains a bridge at the 2',4'-position of ribose to provide the 2',4'-BNA monomer synthesized by the Takeshi Imanishi team. The properties of the bridge can vary according to different types of monomers. BNA monomers can be easily integrated into natural oligonucleotides by standard phosphite amide chemistry, and BNA/DNA and BNA/RNA heterozygous oligonucleotides can be flexibly designed to meet the requirements of high and sequence-specific hybridization with natural nucleic acids and strong nuclease resistance.
So far, the third generation BNA has been developed. 4'-BNA-NC contains a 6-membered ring with a NO bond between the 2'-OH and the 4'-C part of the ribose. It has excellent binding affinity to ssRNA, better binding affinity to dsDNA and excellent enzyme stability to nuclease. As a result, BNA has now become an excellent tool for developing high-value testing systems and therapeutic products. In addition, newer BNA compounds will be introduced in the near future, which brings great hope for the research and application fields based on oligonucleotides.
