Backbone Oligo Modification by Type
November 22, 2024 by Dawn Lam
What backbone chemistries have been used for stereopure oligonucleotides? Traditional oligonucleotide synthesis using standard phosphoramidite methods does not control stereochemistry, resulting in a stereorandom phosphorothioate (PS) mixture where each linkage may adopt either R or S configuration. Studies in retinal disorders, CNS diseases, and muscular atrophy have demonstrated that stereopure oligonucleotides can significantly impact biological […]
