5'-(E)-VP-2'-OMe-A (Bz) Phosphoramidite is a 5'-terminal building block for a 5'-(E)-vinylphosphonate phosphate-mimic motif: a 2'-O-methyl-N6-benzoyladenosine carrying a protected 5'-(E)-vinylphosphonate group at the 5'-position and a 3'-O-(2-cyanoethyl N,N-diisopropyl)phosphoramidite. Its PubChem-backed identity includes CAS 2419895-65-9, molecular formula C40H57N7O12P2, molecular weight 889.9, and PubChem CID 172878654.

Cited literature describes 5'-(E)-vinylphosphonate (5'-VP) as a metabolically stable mimic of the natural 5'-monophosphate, where the bridging 5'-oxygen is replaced by a vinyl carbon. Because the 5'-position carries the vinylphosphonate in place of the usual 5'-DMT, this monomer is the 5'-terminal residue, added last. Cited 2'-OMe literature provides RNA-binding and nuclease-stability context for the 2'-O-methyl group, and N6-benzoyl protection is removed during final deprotection. The protected vinylphosphonate amidite format is cited for solid-phase synthesis.

用途情報

5'-phosphate mimic context: provides a 5'-(E)-vinylphosphonate at the 5'-terminus, described in cited literature as a metabolically stable 5'-phosphate mimic.
5'-terminal residue: the vinylphosphonate occupies the 5'-position (in place of 5'-DMT), so this monomer is added last in the synthesis.
2'-OMe modification: cited 2'-OMe literature provides RNA-binding and nuclease-stability context; N6-benzoyl protection is removed during final deprotection.

よくある質問

Why is this monomer a 5'-terminal residue, and why are there two phosphorus atoms?

The vinylphosphonate occupies the 5'-position (in place of the usual 5'-DMT), so it is added last, at the 5'-end. The two phosphorus atoms are the vinylphosphonate group and the 3'-phosphoramidite coupling group.
