5'-O-DMT-2'-O-MOE-N2-isobutyrylguanosine is 2'-O-(2-methoxyethyl)guanosine carrying a 5'-O-(4,4'-dimethoxytrityl) (DMT) group and an N2-isobutyryl base-protecting group. CH64128 is identified by CAS 251647-50-4, molecular formula C38H43N5O9, molecular weight 713.8, PubChem CID 135741311, and InChIKey XDLPRZLZAFJSMA-BEGXHNNXSA-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 N2-isobutyryl group masks the guanine 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.
N2-isobutyryl base protection: the isobutyryl group masks the guanine exocyclic amine during synthesis and is removed at final deprotection.

常见问题

How does it differ from 2'-O-MOE-N2-isobutyrylguanosine?

Both carry an N2-isobutyryl-protected 2'-O-MOE guanosine, 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.
