  • Publication number: 20080176813
    Abstract: The present invention provides a six membered, at least partially unsaturated, carbocyclic nucleoside compound, including the (?) enantiomer, the (+) enantiomer, and pharmaceutically acceptable salts and esters thereof. The compounds are represented by formula (I), wherein Z represents one double bond in the six membered carbocylic ring, B is a heterocyclic ring, such as a pyrimidine or purine base, X is an azido, F or OR2, R1 and R2 are the same or different and represent the same or different protecting groups, hydrogen, alkyl, alkenyl, acyl or phosphate moieties, and wherein the alkyl moiety is a saturated, optionally unsubstituted hydrocarbon having from 1 to 20 carbon atoms, the alkenyl moiety is an unsaturated congener of the alkyl group, and the acyl moiety is analkanoyl or aroyl moiety.

  • Publication number: 20080069971
    Abstract: The present invention is related to the localised/patterned deposition and/or desorption of (bio)molecules using microelectronic structures. Often pre-existing structures needed for proper functioning of the device (e.g. sensors, . . . ) can be used as individually addressable control structures to achieve localised deposition through thermal and/or electrochemical spotting, thereby reducing the need for and simplifying additional processing steps to achieve localised/patterned deposition. If these multi-purpose structures are not available, additional control structures can be implemented, using microelectronic VLSI production technology.

  • Publication number: 20080038745
    Abstract: The present invention is related to compounds comprising six-membered rings capable of being incorporated into nucleic acids. Particularly, the six-membered ring is a derivative of cyclohexane, cyclohexene, tetrahydropyran, tetrahydrothiopyran or piperidine. These compounds may be used to build up oligomeric compounds. The invention is further related to uses of these oligomeric compounds for hybridization and as probes. In addition, methods for the detection of nucleic acids are provided wherein the oligomeric compounds are used.
