5'-ODMT cEt N-Bz A Phosphoramidite (Amidite) is a nucleoside phosphoramidite monomer for synthesizing locked nucleic acid (LNA) analog oligonucleotides. It acts as a building block for antisense oligonucleotides (ASOs), targeting complementary RNA sequences. This compound features a 2',4'-constrained ethyl (cEt) modification, which enhances hybridization affinity, improves mismatch discrimination with RNA, and significantly increases resistance to exonuclease digestion. It mediates RNase H-dependent mRNA degradation or inhibits translation by forming stable hybrids, thereby regulating gene expression.
- Used in antisense drug development and gene therapy.
- Applicable in molecular biology techniques, including PCR and primer extension.
- Aids in gene silencing and small RNA research.
