A new isoindoline-derived benzimidazole nitroxide spin label, ImUm, was synthesized and incorporated into RNA oligoribonucleotides. ImUm is the first example of a conformationally unambiguous spin label for RNA, in which the nitroxide N-O bond lies on the same axis as the single bond used to attach the rigid isoindoline-based spin label to a uridine base. This results in minimal displacement of the nitroxide upon rotation of this single bond, which is a useful property for a label to be used for distance measurements. Continuous-wave (CW) EPR measurements of RNA duplexes containing ImUm indicate a restricted rotation around this single bond, presumably due to an intramolecular hydrogen bond between the benzimidazole N-H and O4 of the uracil. Orientation-selective pulsed electron-electron double resonance (PELDOR, also called double electron-electron resonance, or DEER) distance measurements between two spin labels in two RNA duplexes showed in one case a strong orientation dependence, further confirming the restricted motion of the spin labels in RNA duplexes.

Paragraph 0053; 0059; 0061; 0294; 0369; 0394, (2021/06/22)
Various embodiments provide STOPS? polymers that are S-antigen transport inhibiting oligonucleotide polymers, processes for making them and methods of using them to treat diseases and conditions. In some embodiments the STOPS? modified oligonucleotides include an at least partially phosphorothioated sequence of alternating A and C units having modifications as described herein. The sequence independent antiviral activity against hepatitis B of embodiments of STOPS? modified oligonucleotides, as determined by HBsAg Secretion Assay, is an EC50 that is less than 100 nM.

5-Formyl-2'-O-methyluridine was incorporated into the various positions of oligonucleotide 26-mers containing the NF-κB binding sequence. Some of them showed binding selectivity toward the homo- and heterodimers of subunits of NF-κB.
