摘要:This invention relates to novel method of synthesis of RNA utilizing N-2-acetyl protected guanine as nucleoside base, nucleosides, succinates, phosphoramidites, corresponding solid supports that are suitable for oligo deoxy nucleosides and RNA oligonucleotide synthesis. Our discovery using N-acetyl protected guanine as nucleoside base protecting group, which is significantly faster base labile protecting group, yet significantly more stable than commonly utilized-2-isobutyryl guanosine is a novel approach to obtain highest purity oligonucleotides. This approach is designed to lead to very high purity and very clean oligonucleotide, after efficient removal of the protecting groups, including acetyl group from guanine and to produce high purity therapeutic grade DNA oligonucleotides, RNA oligonucleotides, diagnostic DNA, diagnostic RNA for microarray platform. The deprotection of acetyl protecting groups of the natural deoxy and ribonucleosides occurs under substantially reduced time in contact with mild deprotection conditions such as mild bases, secondary amines for removal of such groups under such conditions would allows synthesis of various DNA and RNA of highest purity for diagnostics and therapeutic application. This approach is designed to lead to high purity large scale therapeutic grade oligonucleotide chimeras which consist of fluoro sugar modification in conjunction with deoxy nucleosides, ribonucleosides, modified base and modified sugar nucleosides. This approach is further designed to use acetyl guanine protecting group when other bases are sensitive nucleoside, and for use in oligo peptide synthesis and for support bound oligo nucleotides.

摘要:This invention relates to synthesis of novel -N-FMOC protected nucleosides, succinates, phosphoramidites, corresponding solid supports that are suitable for oligo deoxy nucleosides and RNA oligonucleotide synthesis. Our discovery using N-FMOC as nucleoside base protecting group, which is highly base labile protecting group is a novel approach to obtain highest purity oligonucleotides. This approach is designed to lead to very high purity and very clean oligonucleotide, after efficient removal of the protecting groups and to produce high purity therapeutic grade DNA oligonucleotides, RNA oligonucleotides, diagnostic DNA, diagnostic RNA for microarray platform. The deprotection of FMOC protecting groups of the natural deoxy and ribonucleosides occurs under very mild deprotection conditions such as mild bases, secondary and tertiary amines for removal of such groups under such conditions would allows synthesis of various DNA and RNA of highest purity for diagnostics and therapeutic application. This approach is further designed to use FMOC protecting group on various base sensitive nucleoside, and for use in oligo peptide synthesis and for support bound oligo nucleotides. DNA oligonucleotides containing 3′-end dA at the 3′-terminal will be produced using the FMOC-dA-supports would lead to much reduced M−1 deletion sequences, and thereby high purity.

摘要:The present invention relates to the technical field of oligonucleotide synthesis. Disclosed are the use of silicon dioxide microspheres in the synthesis of an ultra-long oligonucleotide and a method for synthesizing an ultra-long oligonucleotide, wherein the silicon dioxide microspheres have a specific surface area of less than 1 m2/g, and preferably, the silicon dioxide microspheres have modification groups on the surface. The method for synthesizing an ultra-long oligonucleotide comprises: performing a coupling reaction on a nucleoside phosphoramidite synthesis unit using the silicon dioxide microspheres having modification groups on the surface as carriers under coupling reaction conditions. The prepared carriers can be used to prepare an ultra-long oligonucleotide.

摘要:Provided herein is a simple, one-step, non-enzymatic synthesis of O-Acetyl-ADP-ribose (OAADPR) from NAD and sodium acetate in acetic acid. The extension of this reaction to other carboxylic acids, demonstrates that the reaction between NAD, and NAD analogs produces mixtures of the corresponding 2′- and 3′-carboxylic esters. Included are O-carboxyl-ADP-ribose compounds and corresponding methods of synthesis (e.g., O-propionyl-ADP-ribose, O-succinyl-ADP-ribose, O-malonyl-ADP-ribose), as well as non-adenosine nucleoside compounds.
