5'-ODMT cEt N-Bz A Phosphoramidite (Amidite)

5'-ODMT cEt N-Bz A Phosphoramidite (Amidite) is a nucleoside phosphoramidite monomer used to synthesize locked nucleic acid (LNA) analog oligonucleotides. It can be used as a building block of antisense oligonucleotides (ASOs) to target complementary RNA sequences. 5'-ODMT cEt N-Bz A Phosphoramidite (Amidite) locks the furanose ring into an N-type conformation through 2',4'-constrained ethyl (cEt) modification, enhancing hybridization affinity and mismatch discrimination with RNA, while significantly improving the resistance of oligonucleotides to exonuclease digestion. 5'-ODMT cEt N-Bz A Phosphoramidite (Amidite) mediates RNase H-dependent mRNA degradation or inhibits translation by forming a stable hybrid with RNA, thereby achieving gene expression regulation. 5'-ODMT cEt N-Bz A Phosphoramidite (Amidite) is mainly used in the development of antisense drugs, gene function research and oligonucleotide synthesis related to disease treatment[1][2].
