  • Patent number: 10527629
    Abstract: The present invention relates to a set of two or more mass labels. Each mass label comprises: X-L-M-Re; X is a reporter moiety having exact mass; L is a bond cleavable by collision in a mass spectrometer; M is a mass modifier; Re is a) a reactive functionality for attaching the mass label to an analyte or b) the analyte. Each mass label in the set has the same integer mass; wherein the set comprises two or more subsets of mass labels, each subset comprising one or more mass labels; wherein, when the subset comprises two or more mass labels, the exact mass of the reporter moiety X of each mass label in the subset is different from the exact mass of the reporter moiety X of the mass labels in the same subset and in all other subsets; each mass label is distinguishable by mass spectrometry.

  • Publication number: 20150057449
    Abstract: One embodiment of the invention provides polyisobutylene (PIB) oligormers that are end-functionalized with ruthenium (Ru) catalysts. Such nonpolar catalysts can be dissolved in nonpolar solvents such as heptane, or any other nonpolar solvent that is otherwise not latently biphasic (i.e., if two or more solvent components are present, they remain miscible with each other throughout the entire reaction process, from the addition of substrate through to the removal of product). Substrate that is dissolved in the nonpolar solvent with the catalyst is converted into product. The lower solubility of the product in the nonpolar solvent renders it easily removable, either by extraction with a more polar solvent or by applying physical means in cases where the product precipitates from the nonpolar solvent. In this manner the catalysts are recycled; since the catalysts remain in the nonpolar solvent, a new reaction can be initiated simply by dissolving fresh substrate into the nonpolar solvent.

  • Publication number: 20140243509
    Abstract: Tissue slices and whole organisms offer substantial challenges to fluorescence imaging. Autofluorescence and absorption via intrinsic chromophores, such as flavins, melanin, and hemoglobins, confound and degrade output from all fluorescent tags. An “optical window,” farther red than most autofluorescence sources and in a region of low hemoglobin and water absorbance, lies between 650 and 900 nm. This valley of relative optical clarity is an attractive target for fluorescence-based studies within tissues, intact organs, and living organisms. Novel fluorescent tags were developed herein, based upon a genetically targeted fluorogen activating protein and cognate fluorogenic dye that yields emission with a peak at 733 nm exclusively when complexed as a “fluoromodule”. This tool improves substantially over previously described far-red/NIR fluorescent proteins in terms of brightness, wavelength, and flexibility by leveraging the flexibility of synthetic chemistry to produce novel chromophores.

    Abstract: Described is a pretargeting method, and related kits, for targeted medical imaging and/or therapeutics, wherein use is made of abiotic reactive chemical groups that exhibit bio-orthogonal reactivity towards each other. The invention involves the use of [4+2] inverse electron demand (retro) Diels-Alder chemistry in providing the coupling between a Pre-targeting Probe and an Effector Probe. To this end one of these probes comprises an electron-deficient tetrazine or other suitable diene, and the other an E-cyclooctene which has a flattened structure as a result of the position of at least two exocyclic bonds.

  • Publication number: 20140093935
    Abstract: Mitigation of photo-induced damage in excitation illuminated reactions and analyses utilizing such reactions results in an enhanced performance for the reactions and the analyses. There is provided a novel class of triplet-state quenchers for mitigating photo-induced damage which are both simple in structure and effective at preventing and/or reducing photo-induced damage to reaction components of excitation illuminated reaction mixtures. Also provided are methods of using the compounds of the invention, devices and kits incorporating the compounds of the invention.

  • Publication number: 20140088308
    Abstract: Chelating monomers and fluoride-releasing compositions are disclosed that may be incorporated into dental composite restorative materials, dental bonding agents or other dental materials, to produce materials with high fluoride release rates, and high fluoride recharge capability. Such dental restorative materials may help reduce the level of dental caries in patients, particularly the level of caries occurring on the margins of the restorative materials.

  • Publication number: 20140081012
    Abstract: Pharmaceutical, chemical and biological agents containing a reversible disulfide linker are described. These agents can also be covalently bound or contained in delivery vehicles for delivering the agents to desired targets or areas. Also described are delivery vehicles which contain an agent having a reversible disulfide linker and to vehicles that are covalently linked to the agent containing a reversible disulfide linker. The modifications described herein can modify properties of the agents and vehicles, thereby providing desired solubility, stability, hydrophobicity and targeting while the reversibility of the linker can leave the agent to which it is attached free from residual chemical groups after being reduced.

  • Publication number: 20140031562
    Abstract: A method of performing a chemical reaction includes reacting an allyl donor and a substrate in a reaction mixture, and forming a homoallylic alcohol in the reaction mixture. The substrate may be an aldehyde or a hemiacetal. The reaction mixture includes a ruthenium catalyst, carbon monoxide at a level of at least 1 equivalent relative to the substrate, and water at a level of at least 1 equivalent relative to the substrate, and an amine at a level of from 0 to 0.5 equivalent relative to the substrate. The reaction mixture may also include a halide, and the equivalents of the amine may be similar to those of the halide. The reacting includes maintaining the reaction mixture at a temperature of at least 40° C. The method may be catalytic in metal, environmentally benign, amenable to large-scale applications, and applicable to a wide range of substrates.
