5'-O-DMT-2'-O-MOE-N4-benzoyl-5-methylcytidine is 2'-O-(2-methoxyethyl)-5-methylcytidine carrying a 5'-O-(4,4'-dimethoxytrityl) (DMT) group and an N4-benzoyl base-protecting group; its base is 5-methylcytosine. CH64127 is identified by CAS 182496-01-1, molecular formula C41H43N3O9, molecular weight 721.8, PubChem CID 15864052, and InChIKey BYSCLUAIKFEFAH-LZURGKRNSA-N.

It is a 2'-O-MOE-modified RNA phosphoramidite precursor context: the acid-labile 5'-DMT group is removed at the start of each chain-elongation cycle, and the N4-benzoyl group masks the cytosine exocyclic amine and is removed at final deprotection. In the cited structure and stability literature, 2'-O-MOE ribonucleosides/residues are discussed in RNA-affinity and nuclease-resistance studies and as flanking residues in gapmer antisense oligonucleotides.

应用背景

5'-DMT 5'-OH protection: the acid-labile 4,4'-dimethoxytrityl group protects the 5'-hydroxyl and is removed at the start of each RNA chain-elongation cycle.
2'-MOE sugar modification: cited structure and stability literature discusses 2'-O-MOE residues in RNA-affinity and nuclease-resistance studies.
N4-benzoyl base protection (5-methylcytosine base): the benzoyl group masks the cytosine exocyclic amine during synthesis and is removed at final deprotection; the base is 5-methylcytosine.

常见问题

How does it differ from 2'-O-MOE-N4-benzoyl-5-methylcytidine?

Both are N4-benzoyl-protected 2'-MOE 5-methylcytidines, but this one also has a 5'-O-DMT group on the 5'-hydroxyl (as a phosphoramidite precursor). The non-DMT form is cataloged separately.
