Chemical Structure
2'-O-MOE-U
- CAS No.: 163759-97-5
- Formula:C42H53N4O10P
- Molecular Weight:804.86
IUPAC Name: 3-(5,5-difluoro-7-(thiophen-2-yl)-5H-4l4,5l4-dipyrrolo[1,2-c:2',1'-f][1,3,2]diazaborinin-3-yl)-N-(prop-2-yn-1-yl)propanamide
InChIKey: ZLOKLUONKGURQI-UAQIPLLRSA-N
SMILES: COC(C=C1)=CC=C1C(C2=CC=C(OC)C=C2)(C3=CC=CC=C3)OC[C@H]4O[C@@H](N5C(NC(C=C5)=O)=O)[C@H](OCCOC)[C@@H]4OP(N(C(C)C)C(C)C)OCCC#N
Biological Activity: 2'-O-MOE-U is a nucleic acid modification group (Phosphoramidite) with 3'-exonuclease inhibitory activity. 2'-O-MOE-U also exhibits gene silencing activity and double-stranded oligonucleotide stability. By forming steric interactions with 3'-exonuclease residues, 2'-O-MOE-U anchors the 3'-end of the siRNA guide strand in the hAgo2 PAZ domain, thereby regulating double-stranded thermal stability and enhancing base-pairing specificity. 2'-O-MOE-U does not induce IFNα production, can be incorporated at multiple sites of siRNA to enhance RNAi activity, and produces a synergistic effect with 2'-F modification. 2'-O-MOE-U has been widely used in studies related to breast cancer and other diseases[1][2].
