  • Gene Activation Strategies in Filamentous Fungi for Natural Products Discovery

    Creator:
    Adpressa, Donovon A.
    Abstract:
    Fungi have long been a prolific source of clinically approved drugs. The antibiotic penicillin, the cholesterol lowering statins, and the immunosuppressant cyclosporine have changed the treatment of human diseases in the last century. Recently, genome analysis of filamentous fungi has revealed that the biosynthetic potential for natural product expression is...

    Lusk, Jason S.
    Abstract:
    Part 1: A Diels-Alder Approach to the Synthesis of Novel Analogues of the Natural Product Siamenol Due to the prevalence of biaryl motifs in natural product synthesis, the Carter research group has been exploring the utility of a Diels-Alder approach to biaryl synthesis. The Diels-Alder approach involves a [4+2] cycloaddition...

  • Studies toward the total synthesis of alkaloids : nagelamide A and D, agelastatin D, dragmacidin A-C, salacin and almazoles

    Creator:
    Tonsiengsom, Sorasaree
    Abstract:
    Studies toward the total syntheses of highly potent cytotoxic alkaloids including the bromopyrrole alkaloids and indole alkaloids were conducted and are described. Studies carried out in the course of this dissertation consist of five total syntheses of natural products that include bromopyrrole alkaloids nagelamide A, D and agelastatin D as...

  • Pactamycin Inspired Drug Discovery: A Synthetic and Chemoenzymatic Approach

    Creator:
    Brumsted, Corey J.
    Abstract:
    Pactamycin, first reported in 1962, is a potent antitumor antibiotic produced by the soil bacterium Streptomyces pactum. Structurally, it contains a cyclopentitol core unit, a 3-aminoacetophenone (3AAP), a 6-methylsalicylic acid (6-MSA), and a N,N-dimethyl urea. The aminocyclopentitol ring is derived from glucose, possibly via N-acetyl glucosamine (GlcNAc), the 3-aminoacetophenone (3AAP)...

  • Rationalization and innovative design of asymmetric organocatalysts through computational investigation

    Creator:
    Johnston, Ryne Connell
    Abstract:
    My work on computing complex catalyzed organic transformations reveals that only a few subtle chemical factors, e.g. non-classical hydrogen bonding, (hyper)conjugation and steric effects, common across different catalyst manifolds are critical for catalysis and selectivity. Rational manipulation and exploitation of these factors has led to improved catalyst designs, which has...
