  • In vivo Reactions of Tetrazines Incorporated through Genetic Code Expansion

    Creator:
    Blizzard, Robert J.
    Abstract:
    The inverse electron demand Diels Alder reaction between tetrazines and strained alkenes is an exceptionally useful tool in functionalizing to biomolecules since it is orthogonal to the chemistry of most living systems and have exceptionally high rate constants. In particular reactions between strained trans-cyclooctenes (sTCO) and tetrazines can achieve second...

  • Gadusol Production in Saccharomyces cerevisiae

    Creator:
    Holzwarth, Garrett
    Abstract:
    Gadusol is a UV-B-absorbent compound found in fish and other marine organisms where it is presumed to play a role as a sunscreen and antioxidant. In light of commercial potential as a replacement for problematic synthetic sunscreens, a process to produce recombinant gadusol in the yeast Saccharomcyces cerevisiae was investigated....

  • Tracking Excited State Proton Transfer and Inhibition with Ultrafast Raman and Transient Absorption Spectroscopy

    Creator:
    Oscar, Breland G.
    Abstract:
    In this dissertation, excited state proton transfer (ESPT) and its inhibition in solution and protein environments are revealed using both femtosecond transient absorption (fs-TA) spectroscopy and femtosecond stimulated Raman spectroscopy (FSRS). Using a tunable Raman pump to enhance transient vibrational features of the photoacidic chromophore HPTS in methanol and methanol...

  • Dietary organosulfur and organoselenium compounds as HDAC inhibitors

    Creator:
    Nian, Hui
    Abstract:
    Histone deacetylase (HDAC) inhibitors have the potential to de-repress epigenetically silenced genes in cancer cells, leading to cell cycle arrest and apoptosis. Dietary HDAC inhibitors derived from natural phytochemicals are promising anticancer agents. In this thesis, metabolites from natural organosulfur and organoselenium compounds, i.e. allyl mercaptan (AM), β-methylselenopyruvate (MSP) and...
