专利号:US-12188072-B2 优先权日:2018-03-19 标题 :Compositions and methods for rapid in vitro synthesis of bioconjugate vaccines in vitro via production and N-glycosylation of protein carriers in detoxified prokaryotic cell lysates 发明人:JEWETT MICHAEL CHRISTOPHER; STARK JESSICA CAROL; DELISA MATTHEW P; JAROENTOMEECHAI THAPAKORN 权利人:UNIV NORTHWESTERN; UNIV CORNELL 摘要:Disclosed are methods, systems, components, and compositions for cell-free synthesis of glycosylated carrier proteins. The glycosylated carrier proteins may be utilized in vaccines, including anti-bacterial vaccines. The glycosylated carrier proteins may include a bacterial polysaccharide conjugated to a carrier, which may be utilized to generate an immune response in an immunized host against the polysaccharide conjugated to the carrier. The glycosylated carrier proteins may be synthesized in cell-free glycoprotein synthesis (CFGpS) systems using prokaryote cell lysates that are enriched in components for glycoprotein synthesis such as oligosaccharyltransferases (OSTs) and lipid-linked oligosaccharides (LLOs) including OSTs and LLOs associated with synthesis of bacterial O antigens.

专利号:US-2024092821-A1 优先权日:2020-03-31 标题:Synthesis of oligonucleotides and related compounds 发明人:ZHONG MINGHONG; JIN YI; GALA DINESH; PRHAVC MARIJA 权利人:JANSSEN BIOPHARMA INC 摘要:Methods of synthesizing oligonucleotides via new intermediates on a cleavable support having an azidomethyl moiety are disclosed. The method comprises multiple reaction cycles, each of which comprises sequential coupling a nucleoside or oligonucleotide subunit on a cleavable support having an azidomethyl moiety and a nucleoside phosphoramidite or an oligonucleotide phosphoramidite, capping, oxidation/thiolation and deblocking; followed by orthogonal cleavage of the azidomethyl support while keeping all other protecting groups intact. The method can be used in combination with a support moiety for either solid phase or liquid phase oligo synthesis. The soluble support facilitates homogeneous reactions and efficient separations by simple precipitation. The methods also provide novel intermediates useful in the synthesis of oligonucleotide conjugates.

Hudson,Ali Heidari,Timothy Martin-Chan,Gyeongsu Park,James A. Wisner |发布日期:2019.11.1 摘要:Protecting Groups For Thiouracil (Su) For The Synthesis Of Pseudo-Complementary Peptide Nucleic Acid (Pna) Has Been Evaluated. The 4-Methoxybenzyl-Protecting Group That Has Found Use For Su During Boc-Based Oligomerization Is Also Suitable For Fmoc-Based Oligomerization. Furthermore, It Is Demonstrated That Su Protection Is Unnecessary For The Successful Synthesis Of Thiouracil-Containing Pna. The New 2-Thiothymine
