摘要:The present invention describes a novel method for the solid phase synthesis of polyamides containing imidazole and pyrrole carboxamides. The polyamides are prepared on a solid support from aromatic carboxylic acids and aromatic amines with high stepwise coupling yields (>99%), providing milligram quantities of highly pure polyamides. The present invention also describes the synthesis of analogs of the natural products Netropsin and Distamycin A, two antiviral antibiotics. The present invention also describes a novel method for the solid phase synthesis of imidazole and pyrrole carboxamide polyamide-oligonucleotide conjugates. This methodology will greatly increase both the complexity and quantity of minor-groove binding polyamides and minor-groove binding polyamide-oligonucleotide conjugates which can be synthesized and tested.

摘要:This invention provides a method for monitoring the transcriptional synthesis of RNA, and to an apparatus therefor. Specifically, the invention resides in monitoring the initiation and termination of a transcription reaction for RNA synthesis, as well as the synthesis of full-length RNA by measuring the fluorescence of a pair of oligonucleotide probes of two types having a base sequence that continuously hybridizes to a part of a base sequence of the RNA synthesized by transcription, the pair of oligonucleotide probes comprising a donor probe labeled with an energy donor fluorescent molecule and an acceptor probe labeled with an energy acceptor fluorescent molecule.

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 discloses novel methods for the synthesis of oligonucleotides with nucleoside phosphoramidites on solid supports. The methods comprise the stepwise chain assembly of oligonucleotides on supports with 5′-acyl phosphoramidites. The synthesis cycles consist of a front end deprotection step which is conducted with a solution of a primary amine or a phenolate, a phosphoramidite coupling step with a 5′-acyl nucleoside phosphoramidite in the presence of an activator, a phosphite oxidation step and an optional capping step. The novel methods improve the quality of synthetic oligonucleotides due to the irreversibility of the front end deprotection step, which prevents the formation of deletion sequences, and due to the avoidance of acidic reagents in the synthesis cycles, which prevent the formation of depurination side products. The invention further discloses novel nucleoside phosphoramidite compositions wherein the phosphoramidites carry acyl front end protective groups which are cleavable with primary amines or phenolates. The invention is applicable to the synthesis of oligodeoxyribonucleotides, oligoribonucleotides and oligonucleotides with modifications in their sugar or phosphate groups.

摘要:The compounds of the invention are exemplified by the class of diglycolate synthesis supports particularly useful as support reagents for the direct synthesis of 3'-labeled polynucleotides. Generally, the compounds of the invention have the structure ##STR1## where T is an acid-cleavable hydroxyl protecting group, e.g., 4,4'-dimethoxytrityl; L 1 is a linker for connecting a 3'-terminal nitrogen to carbon; L 2 and L 3 are linkers for connecting oxygen and carbon; W is a solid support, e.g., CPG or polystyrene; L 4 is a linker for connecting the solid support to nitrogen; R 1 and R 2 are nitrogen substituents, e.g., hydrogen, lower alkyl, nitrogen protecting group, or label; and R 3 through R 7 are carbon substituents, e.g., hydrogen or lower alkyl. In a first particularly preferred embodiment, the synthesis supports of the invention are exemplified by compounds having the structure ##STR2## where DMT is 4,4'-dimethoxytrityl and W is polystyrene. In a second particularly preferred embodiment, the synthesis supports of the invention are exemplified by compounds having the structure ##STR3## where DMT and W are defined above.
