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.

标题 :Synthesis of N-substituted oligomers

摘要:A solid-phase method for the synthesis of N-substituted oligomers, such as poly (N-substituted glycines) (referred to herein as poly NSGs) is used to obtain oligomers, such as poly NSGs of potential therapeutic interest which poly NSGs can have a wide variety of side-chain substituents. Each N-substituted glycine monomer is assembled from two 'sub-monomers' directly on the solid support. Each cycle of monomer addition consists of two steps: (1) acylation of a secondary amine bound to the support with an acylating agent comprising a leaving group capable of nucleophilic displacement by -NH2, such as a haloacetic acid, and (2) introduction of the side-chain by nucleophilic displacement of the leaving group, such as halogen (as a resin-bound alpha -haloacetamide) with a sufficient amount of a second sub-monomer comprising an -NH2 group, such as a primary amine, alkoxyamine, semicarbazide, acyl hydrazide, carbazate or the like. Repetition of the two step cycle of acylation and displacement gives the desired oligomers. The efficient synthesis of a wide variety of oligomeric NSGs using automated synthesis technology of the present method makes these oligomers attractive candidates for the generation and rapid screening of diverse peptidomimetic libraries. The oligomers of the invention, such as N-substituted glycines (i.e. poly NSGs) disclosed here provide a new class of peptide-like compounds not found in nature, but which are synthetically accessible and have been shown to possess significant biological activity and proteolytic stability.

标 题 :Method for the controlled synthesis of polynucleotide mixtures which encode desired mixtures of peptides
发明人：GEYSEN H MARIO
权利人:CHIRON CORP
摘要:A method to obtain selected individual polynucleotides or mixtures thereof each of which encodes a peptide and at least one polynucleotide of the mixture encodes a peptide having a target property. The polynucleotides of the invention present in the mixture in detectable, retrievable, and clonable amounts are expressed in a host organism for screening for the target activity. The invention features the ability to synthesize controlled random polynucleotides to produce a predetermined mixture of polynucleotides and to avoid synthesis of a stop codon by adjusting the proportions into which the synthesis pool is subdivided and by adjusting the proportions of activated nucleotides added at each coupling step. A polynucleotide encoding a peptide having a target property can be selected and sequenced to deduce the amino acid sequence of the peptide.

The diversity of product compounds is generated by the sequential addition of substituted submonomers. The combinatorial library includes 10 or more, preferably 100 or more, and more preferably 1,000 or more distinct and different compounds.
