LNA-G(dmf) CE Phosphoramidite is the locked nucleic acid (LNA) guanosine building block for oligonucleotide synthesis: a 2'-O,4'-C-methylene-bridged (locked) N2-dimethylformamidine-guanosine with a 5'-O-(4,4'-dimethoxytrityl) group and a 3'-O-(2-cyanoethyl N,N-diisopropyl)phosphoramidite group. CH65049 is identified by CAS 709641-79-2, molecular formula C44H53N8O8P, molecular weight 852.9, PubChem CID 161667440, and InChIKey ACJXYPZQPQPGNE-KPKUBJDASA-N.

The cited LNA literature discusses locked 2'-O,4'-C-methylene sugar structures in relation to oligonucleotide binding affinity and nuclease resistance. As a phosphoramidite, the 3'-phosphoramidite couples to the growing chain, the acid-labile 5'-DMT is removed each cycle, and the N2-dmf base group is removed at final deprotection.

응용 맥락

  • LNA coupling monomer: the 3'-O-(2-cyanoethyl N,N-diisopropyl)phosphoramidite is the reactive group that couples to the growing oligonucleotide chain in automated solid-phase synthesis.
  • Locked (LNA) sugar: the cited LNA literature discusses the 2'-O,4'-C-methylene bridge in relation to oligonucleotide binding affinity and nuclease resistance.
  • 5'-DMT + N2-dmf protection: the acid-labile 5'-DMT is removed each cycle, and the N2-dimethylformamidine base group is removed at final deprotection.

자주 묻는 질문

What residue identity does this LNA amidite provide?

It provides the locked (LNA) guanosine residue identity through its 3'-phosphoramidite coupling group, with 5'-DMT removed each cycle and N2-dmf removed at final deprotection.

How does it differ from the LNA-G(iBu) amidite?

Both are LNA (locked) guanosine phosphoramidites, but this one uses an N2-dimethylformamidine (dmf) base protection rather than isobutyryl. The isobutyryl amidite is cataloged separately.
