LNA-A(Bz) CE Phosphoramidite is the locked nucleic acid (LNA) adenosine building block for oligonucleotide synthesis: a 2'-O,4'-C-methylene-bridged (locked) N6-benzoyladenosine with a 5'-O-(4,4'-dimethoxytrityl) group and a 3'-O-(2-cyanoethyl N,N-diisopropyl)phosphoramidite group. CH65045 is identified by CAS 206055-79-0, molecular formula C48H52N7O8P, molecular weight 885.9, PubChem CID 13009021, and InChIKey HPIDKMAOZZZGOP-LIUGLABVSA-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 N6-benzoyl 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 + N6-benzoyl protection: the acid-labile 5'-DMT is removed each cycle, and the N6-benzoyl base group is removed at final deprotection.

자주 묻는 질문
What is LNA and what does this amidite do?
LNA (locked nucleic acid) contains a rigid 2'-O,4'-C-methylene bridge. This amidite's 3'-phosphoramidite couples to the growing chain, with 5'-DMT removed each cycle and N6-benzoyl removed at final deprotection.
How does LNA differ from 2'-OMe or 2'-F modifications?
They are different sugar-modification chemistries: LNA locks the sugar with a 2'-O,4'-C-methylene bridge, while 2'-OMe and 2'-F are 2'-substituted ribose/deoxyribose analogs. The 2'-OMe and 2'-F amidites are cataloged separately.
