  • Publication number: 20150011001
    Abstract: The present invention provides compositions and methods for the optimization of cleavage of RNA species by RNase H. In some embodiments, the invention provides oligonucleotides that possess two or more regions of differing conformation, and at least one transitional nucleobase positioned between the regions that is capable of modulating transfer of the helical conformation characteristic of the region bound to the 3? hydroxy thereof, to the region bound to the 5? hydroxyl thereof.
    Type: Application
    Filed: June 13, 2014

  • Patent number: 8703728
    Abstract: The present invention relates to bicyclic nucleosides and oligomeric compounds comprising at least one such nucleoside. These oligomeric compounds typically have enhanced binding affinity and nuclease resistance properties compared to unmodified oligomeric compounds. The oligomeric compounds are useful, for example, for investigative and therapeutic purposes.

  • Patent number: 8513404
    Abstract: A process for manufacturing an oligonucleotide which comprises removing ?-eliminating phosphorus-protecting groups, in particular ?-cyanoethyl protective groups from a protected oligonucleotide, wherein said removing comprises contacting the protected oligonucleotide with an amine solution in a solvent which preferably does not consist of pyridine, wherein the conjugate acid of the amine has preferably a pKa of greater than 11.5, and wherein the concentration of the amine in the solution is less than 0.5 mole/liters.
