摘要:A process for the synthesis of oligonucleotides using phosphoramidite chemistry is provided. The process employs as activator a 1,1-dioxo-1,2-dihydro-1λ6-benzo[d]isothiazol-3-one, preferably in the presence of an organic base. The 1,1-dioxo-1,2-dihydro-1λ6-benzo[d]isothiazol-3-one is represented by the following structural formula: wherein p is 0 or an integer from 1 to 4; X7 is O or S; R for each occurrence is a substituent, preferably each independently, a halo, a substituted or unsubstituted aliphatic group, —NR11R12, —OR13, —OC(O)R13, —C(O)OR13, or cyano; or two adjacent R groups taken together with the carbon atoms to which they are attached form a six membered saturated or unsaturated ring; R11 and R12 are each, independently, —H, a substituted or unsubstituted aliphatic group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted aralkyl group; and R13 is a substituted or unsubstituted aliphatic group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted aralkyl group. Preferred organic bases are pyridine, 3-methylpyridine, or N-methylimidazole.

摘要:The present invention relates to synthesis, purification and methods to obtain high purity novel 2′-arabino-O-methyl nucleosides and the corresponding phosphoramidites of various arabinonucleoside bases and introduction of such units into defined sequence synthetic DNA and RNA. Various synthetic oligonucleotides, such as HIV integrase inhibitor 14-mer and thrombin binding oligonucleotide, thrombin-1, bearing ara-2′-omethyl modification have been synthesized. It is anticipated the oligonucleotides incorporating these monomers will exhibit biological activities related to antisense approach approach, design of better SiRNA's, diagnostic agents. Similarly, it is anticipated that oligonucleotides incorporating such novel nucleosides will be useful to develop therapeutic candidates designing stable G-quadruplexes and Aptamers for oligonucleotide structure, folding topology, evaluation of biochemical properties and design and develop as therapeutic agents. It is further anticipated that the nucleosides, phosphates and triphosphates of this invention could develop as therapeutic agents.

权利人:AVECIA BIOTECHNOLOGY INC
摘要:A process for the synthesis of an oligonucleotide is provided in which an oligonucleotide is assembled on a swellable solid support using the phosphoramidite approach in the presence of an activator, wherein the activator is not tetrazole or a substituted tetrazole. Preferred activators are pyridinium, imidazolinium and benzimidazolinium salts; benzotriazole and derivatives thereof; and saccharin or a saccharin derivative. Preferred swellable solid supports comprise functionalised polystyrene, partially hydrolysed polyvinylacetate or poly(acrylamide).

摘要:The synthesis of capped/tagged RNA, methods of use and kits providing same are contemplated. Tagged RNA permits isolation of RNA transcripts in vitro. The ability to isolate and purify capped RNA results in improved transcription and translation and provides a tool for identifying RNA-protein interactions. Such capped RNA finds use in therapeutic applications, diagnosis and prognosis and in the treatment of cancers and HIV.

摘要:The present invention provides building blocks and methods for synthesizing very pure RNA in a form that can efficiently be modified at the 3′ end. Reverse RNA monomer phosphoramidites have been developed for RNA synthesis in 5′→3′ direction, leading to very clean oligo synthesis that allows for the introduction of various modifications at the 3′-end cleanly and efficiently. Higher coupling efficiency per step have been observed during automated oligo synthesis with the reverse RNA amidites disclosed herein, resulting in a greater ability to achieve higher purity and produce very long oligonucleotides. The use of the reverse RNA phosphoramidites in the synthetic process of this invention leads to oligonucleotides free of N+1 species.
