-
Paragraph 0042; 0215, (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.

Regioselective protection of primary hydroxyl group in nucleoside and carbohydrate analogs was accomplished using dimethoxytrityl alcohol (DMTr-OH) or dimethylpixyl alcohol (DMPx-OH) in presence of copper(II)nitrate as a Lewis acid catalyst. Excellent selectivity was observed for the protection of primary hydroxyl group over secondary while glycosidic bond remain unaffected. Utility of this methodology was further exemplified via DMTr- and DMPx-protection of alipahtic acyclic and cyclic diols.

Paragraph 0119, (2018/04/26)
What is described is a trinucleotide cap analog comprising m7G(5′)p3-N1pN2 for increased efficiency of in vitro transcription of m7G(5′)p3-RNA, wherein m7G is N7-methylguanosine or analog, (5′)p3 is a 5′,5′-triphosphate bridge, and N1 or N2 or both ribonucleotide analogs linked to each other by a phosphate, p, and wherein the trinucleotide cap analog increases the efficiency of in vitro transcription.

Synthesis of Leishmania mRNA 5′-cap analogs, m7Gpppm26AmpAm (cap-2), and m7Gpppm26AmpAmpCm (cap-3) is reported. Binding affinities of those cap analogs for LeishIF4E proteins were determined using fluorescence spectroscopy. Cap-3 showed similar affinity to LeishIF4Es compared to the mature trypanosomatids cap structure (cap-4). Copyright Taylor & Francis Group, LLC.

, p. 1629 - 1632 (2007/10/03)
The facile preparation of two novel classes of nucleoside analogs for the inclusion as dimeric non-phosphorous containing subunits in chime fie backbones has been accomplished. The concise preparation of 3'- formylnucleosides and 5'-O-(N-methylhydroxylamino)-nucleosides is reported.
Oligo(2′-O-methylribonucleotides) and their derivatives. II. Synthesis and properties of oligo(2′-O-methylribonucleotides) modified with N-(2-hydroxyethyl)phenazinium and steroid groups at the 5′-terminus

, p. 800 - 806 (2007/10/03)
Oligo(2′-O-methylribonucleotides) modified at the 5′-terminus with a steroid (cholesterol or testosterone) or polycyclic aromatic dye N-(2-hydroxyethyl)phenazinium residue were synthesized. It was shown that the introduction of an N-(2-hydroxyethyl)phenazinium moiety into octa(2′-O-methylribonucleotide) increased the melting temperature of the duplex with the d-target by 9°C. The steroid residue, which was attached to the 5′-position of deca(2′-O-methyluridylate) via a phosphodiester linkage, enhanced the stability of the steroid conjugate complexes with d(pA)16 and (pA)16; this effect was stronger with the cholesterol derivative (ΔTm 5 and 8°C, respectively) than with the testosterone derivative(ΔTm 1 and 4°C).
