  • Patent number: 7923582
    Abstract: The present invention features a chemoselective ligation reaction that can be carried out under physiological conditions. In general, the invention involves condensation of a specifically engineered phosphine, which can provide for formation of an amide bond between the two reactive partners resulting in a final product comprising a phosphine moiety, or which can be engineered to comprise a cleavable linker so that a substituent of the phosphine is transferred to the azide, releasing an oxidized phosphine byproduct and producing a native amide bond in the final product. The selectivity of the reaction and its compatibility with aqueous environments provides for its application in vivo (e.g., on the cell surface or intracellularly) and in vitro (e.g., synthesis of peptides and other polymers, production of modified (e.g., labeled) amino acids).

  • Publication number: 20110077389
    Abstract: Novel CE-phosphoramidites and CPG reagents have been synthesized from a serinol backbone. These reagents are useful to introduce functional groups or directly label oligonucleotides. The versatile serinol scaffold allows for labeling at any position (5? or 3? termini, or any internal position) during automated DNA synthesis. Multiple labels or functional groups can be achieved by repetitive coupling cycles. Optimal spacer arms and protected label moieties have been specially designed. Further, the natural 3-carbon atom internucleotide phosphate distance is retained when inserted internally.

  • Patent number: 7745614
    Abstract: A universal linker structure is provided, in which a functional group and activating leaving group are placed on a tether, allowing the placement of an electrophile at the end of any nucleic acid sequence. The electrophile on the tether can react with a second nucleic acid carrying a nucleophile when the two nucleic acids are hybridized near one another, resulting in release of the leaving group, and creation of a functional change. The linker can be designed to destabilize the ligation product without slowing the rate of reaction. This lowers product inhibition, and the target DNA or RNA can become a catalyst for isothermally generating multiple signals for detection. This enhanced signal is demonstrated in solution experiments and in solid supported assays. The universal linkers of the present invention are simple and inexpensive to prepare, and can be appended to any polynucleotide in automated steps on a standard DNA synthesizer.

  • Publication number: 20080318767
    Abstract: A phosphazene-supported catalyst in which a support is bonded to a group represented by the general formula (1): wherein n, Zn?, a, b, c, d, R, R1 and D are all defined. The phosphazene-supported catalyst is highly effective to catalyze various organic reactions, and further has no reduction of activity even after recovery and reuse of the catalyst, thus it being economically advantageous. In addition, the polymerization of cyclic monomers, substitution of substituents, carbon-carbon bond forming reactions and the like can be conducted with extremely high efficiency.

  • Publication number: 20080214801
    Abstract: The present invention features a chemoselective ligation reaction that can be carried out under physiological conditions. In general, the invention involves condensation of a specifically engineered phosphine, which can provide for formation of an amide bond between the two reactive partners resulting in a final product comprising a phosphine moiety, or which can be engineered to comprise a cleavable linker so that a substituent of the phosphine is transferred to the azide, releasing an oxidized phosphine byproduct and producing a native amide bond in the final product. The selectivity of the reaction and its compatibility with aqueous environments provides for its application in vivo (e.g., on the cell surface or intracellularly) and in vitro (e.g., synthesis of peptides and other polymers, production of modified (e.g., labeled) amino acids).
