Abstract: The invention provides synthons containing a novel carbamate internucleoside linkage, methods for using such synthons to make oligonucleotides containing such novel carbamate linkages, and oligonucleotides containing such novel carbamate linkages.

Abstract: The invention provides new methods for synthesizing oligonucleotides that allow for deprotection of the oligonucleotides under more mild conditions than existing methods. The invention further provides a nucleoside base protecting group that is stable under oligonucleotide synthesis conditions, but which can be removed under more mild conditions than existing protecting groups, as well as nucleoside synthons having such base protecting groups.

Abstract: The invention provides new processes for synthesizing oligonucleotides that allow for deprotection of the oligonucleotide under more rapid and/or more mild conditions than existing methods. The invention further provides a nucleoside base protecting group that is stable under oligonucleotide synthesis conditions, but which can be removed under more mild conditions than existing protecting groups, as well as nucleoside synthons having such base protecting groups. The invention also provides oligonucleotides containing any of a variety of base labile functionalities and methods for using such oligonucleotides.

Abstract: The invention provides new primary phosphoramidate internucleoside linkages that are less sterically constrained than existing phosphoramidate linkages, as well as oligonucleotides containing such linkages and processes for making and methods for using such oligonucleotides.

Abstract: The invention provides new reagents and an improved process for synthesizing oligonucleotides that contain methylphosphonate internucleoside linkages. The reagents and process utilize a nucleoside base protecting group that is stable under oligonucleotide synthesis conditions, but which can be removed under more mild conditions than existing protecting groups.

Abstract: The invention provides oligonucleotides containing methyl phosphotriester linkages and processes for making and methods for using such oligonucleotides.

Abstract: The present invention provides novel compounds and methods for purifying oligonucleotides. The compounds according to the invention are multimeric oligonucleotides comprising a multimerization domain for inducing multimeric oligonucleotide aggregation, a hybridization domain that is complementary to a target oligonucleotide whose isolation is desired, and a linker domain connecting the multimerization domain and the hybridization domain. Other compounds of the invention comprise dendrimers having oligonucleotides with hybridization domains linked thereto.The methods of the invention comprise contacting the compounds of the invention with a solution containing a target oligonucleotide whose purification is desired. The target oligonucleotide hybridizes to the hybridization domain of the inventive compounds, thereby forming an aggregate. Synthetic failure sequences (N-1, N-2, etc.

Abstract: Disclosed is a composition including an oligonucleotide complexed with a cyclodextrin. The oligonucleotide may be noncovalently associated with the cyclodextrin. Alternatively, the oligonucleotide may be covalently complexed with adamantane which is noncovalently associated with the cyclodextrin. Also disclosed are methods of enhancing the cellular uptake and intracellular concentration of oligonucleotides, methods of increasing the solubility of an oligonucleotide in a cell, and methods of treating a cell for viral infection or to prevent viral infection.
