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 invention provides a novel method for the chemical synthesis of 2′,3′-cyclic phosphate and phosphorothioate of mono and terminated oligonucleotides synthesis. The invention also provides a novel method of for the chemical synthesis of 2′,3′- and 3′,5′-cyclic phosphate and phosphorothioate mononucleotide nucleotides. The process is based on quick and efficient cyclization of phosphoramidate moiety and neighboring hydroxyl group. The present invention is directed towards the synthesis of high purity DNA and RNAs, specifically to introduce cyclic phosphate at 3′-end of oligonucleotides. Such DNA and RNA's have extensive application in therapeutics, diagnostics, drug design, and selective inhibition of an RNA sequence within cellular environment, in pre-tRNA cleavage and in ribozyme ligation. The 2′,3′-cyclic phosphate nucleosides are involved in a vast number of applications in molecular biology in general and mammalian cells in particular. The invention also envisions providing kits comprising at least one composition disclosed in the present invention.

摘要:In this method, an oligonucleotide represented by formula (II) [wherein Y 1 , Q, Base, r and r′ are each as defined in claim 1 ] is prepared by using, as a synthesis unit, a novel nucleoside monomer compound represented by formula (I) [wherein X, R 1 , Y, Base, Z, Ar, R 2 , R 3 and n are each as defined in claim 1 ]. The novel nucleoside monomer compound is a nucleoside, the base moiety of which is substituted with an aromatic-hydrocarbon-ring-carbonyl or -thiocarbonyl group having at least one hydrophobic group. The method can dispense with column-chromatographic purification in every reaction, and enables base elongation not only in the 3′-direction but also in the 5′-direction, thus attaining efficient liquid-phase mass synthesis of an oligonucleotide.
