  • Himeradine A : synthetic efforts towards himeradine A and related natural products, a Michael reaction focused approach

    Creator:
    Collett, Nathan D.
    Abstract:
    Lycopodium alkaloids have generated enormous amounts of interest from the scientific community, both as synthetic targets and for their medicinal properties. Herein is described work towards a unifying approach to large segments of the Lycopodium family. An organocatalyzed intramolecular heteroatom Michael reaction method, for the construction of piperidine and piperizine...

  • Development of organocatalyzed, intramolecular heteroatom Michael addition and application towards alkaloid synthesis

    Creator:
    Carlson, Erik
    Abstract:
    Effective methods for the enantiopure formation of substituted piperidine rings are significantly important due to their presence in alkaloid products. A valuable method to form these ring systems would be via an intramolecular heteroatom Michael addition from the corresponding enone or enal. Described herein is a methodolgy that has been...

  • Aqueous complexation of citric acid and DTPA with selected trivalent and tetravalent f-elements

    Creator:
    Brown, M. Alex
    Abstract:
    Carboxylic acids have played an important role in the field of actinide (An) and lanthanide (Ln) separations and the reprocessing of irradiated nuclear fuel. Recent bench-scale experiments have demonstrated that 3-carboxy-3-hydroxypentanedioic acid (citric acid) is a promising aqueous complexant that can effectively aid in the separation of transition metals from...

  • Graphite intercalation compounds containing fluoroanions

    Creator:
    Katinonkul, Watcharee
    Abstract:
    New chemical synthesis strategies have been investigated for the preparation of acceptor-type graphite intercalation compounds (GIC's) with fluoroanions in order to obtain new materials and to develop a better understanding of the synthetic approaches and properties of the products. New GIC's containing borate chelate anion such as bis(oxalato)borate, CxB[OC(O)C(O)O]₂•δF, are...

  • Proteomic approach to the analysis of DNA-binding proteins using mass spectrometry

    Creator:
    Stapels, Martha Degen
    Abstract:
    In proteomic studies, separate experimental protocols have been necessary to identify proteins, determine their function, and predict their three-dimensional structure. In this study, a function-based separation of proteins was conceived to fractionate proteins prior to enzymatic digestion. In the initial demonstration of this technique, a DNA substrate was used to...

  • Mass spectrometric analysis of UV-crosslinked protein-nucleic acid complexes

    Creator:
    Doneanu, Catalin E.
    Abstract:
    The DNA-binding domains of E. coli uracil-DNA glycosylase (Ung) and human replication protein A (hRPA) were studied using a general protocol developed in our laboratory for probing protein-DNA interactions. The procedure involves purification and mass spectrometric analysis of the nucleopeptide-products of a tryptically digested UV-crosslinked protein-nucleic acid complex. In the...

  • Bioactivity Screening and Gene Activation Strategies in Fungi

    Creator:
    Coddington, Nathan C.
    Abstract:
    Natural products from plants, bacteria, and fungi play an important role in society. Over the last 35 years, natural products and their derivatives have inspired over 60% of all FDA approved small-molecule drugs, and are among the top prescribed therapeutics.1-2 Fleming’s discovery of the fungal antibiotic penicillin started the “Golden...

  • New Graphite Intercalation Chemistry with Ethers and Amines

    Creator:
    Zhang, Hanyang
    Abstract:
    Novel donor-typed ternary graphite intercalation compounds (GICs) are synthesized and characterized containing (1) pyrrolidinium cations with DMSO co-intercalates; (2) alkali metal cations with crown ether co-intercalates; and (3) alkali metal cations with polyethylene glycol co-intercalates. Structural and compositional data are obtained for the stable products. A new ether-amine co-intercalate exchange...

  • Graphite intercalation compounds containing tetra-n-alkylammonium cations

    Creator:
    Sirisaksoontorn, Weekit
    Abstract:
    Novel donor-type graphite intercalation compounds (GICs) containing tetra-n-alkylammonium (TAA) cations have been synthesized by using both ion-exchange and electrochemical methods. Structural and compositional data of the resulting TAA-GICs are investigated by using powder X-ray diffraction (PXRD), one-dimensional electron density calculations, thermogravimetric and elemental analyses, and capillary zone electrophoresis (CZE). A...
