Identification of a Bioactive Aryl Ether from a South African Tunicate

Creator:: White, Cora L.
Abstract:: Chemical compounds produced by organisms, or natural products, are excellent sources of inspiration for anticancer pharmaceutical discovery (Rodrigues et al., 2016). Microtubule targeting agents are a specific class of compounds, often discovered from natural sources, that have been developed as clinically successful anticancer therapies (Steinmetz and Prota, 2018). In the...

Molecular origins of peptide entrapment in polyethylene oxide layers

Creator:: Wu, Xiangming
Abstract:: A more quantitative understanding of peptide entrapment and elution from otherwise protein-repellent polyethylene oxide (PEO) brush layers will provide direction for development of new strategies for drug storage and delivery. Here we describe criteria for peptide integration and structural change within the PEO brush, and discuss the reversibility of peptide...

Biochemical Studies of Pactamycin Biosynthesis in Streptomyces pactum

Creator:: Eida, Auday
Abstract:: Ribomimetic natural products have long been known for their important biological activities. Structurally, they contain a densely functionalized cyclopentane unit that resembles ribose. Pactamycin, the prominent member of this class of natural products, is a potent protein synthesis inhibitor produced by the soil bacterium Streptomyces pactum. In pactamycin, the aminocyclopentitol...

Mass Spectrometry-based Analysis of Superwarfarins and their Metabolites and the Investigation of Novel Treatments for Poisoned Victims

Creator:: Nosal, Daniel Grzegorz
Abstract:: Superwarfarins are anticoagulant rodenticides that are 100 times more potent and 15 times more persistent than warfarin. They have been used since the 1980s and cause over 10,000 cases of accidental and intentional poisonings per year. Apart from inducing uncontrollable bleeding, by inhibiting the vitamin K cycle, superwarfarins can disrupt...

Secondary Metabolism in Tolypocladium : Characterization, Ecology, Evolution and Regulation

Creator:: Blount, Rheannon Rua
Abstract:: An increased understanding of secondary metabolism in fungi is important for both biological and societal reasons. The ascomycete genus, Tolypocladium, is an ideal system to explore secondary metabolism characterization, ecology, evolution and regulation. The genus produces and has the genomic potential to produce a wide array of metabolites. Paired with...

Strategies for the Synthesis of Nitrogeous Compounds : Aminal Radical Reaction and Pyridinium Oxide Cycloadditions

Creator:: Lu, Yi
Abstract:: Pharmaceuticals, molecular catalysts, and secondary metabolites often contain nitrogen. The problems faced synthesizing compounds which contain nitrogen was because of the Lewis base reactivity of nitrogen lone pairs, and the acidic protons of some nitrogenous functional groups. We developed two methods for the synthesis of nitrogeous compounds. Additionally, we successfully...

Characterization and Validation of Neisseria gonorrhoeae Proteins GmhAGC and NGO1985 as Molecular Targets for Development of Novel Anti-gonorrhea Therapeutic Interventions

Creator:: Wierzbicki, Igor H.
Abstract:: The sexually transmitted disease gonorrhea, caused by the Gram-negative bacterium and obligate human pathogen Neisseria gonorrhoeae, remains a significant health and economic burden worldwide. In the absence of a protective vaccine, antimicrobial agents are the only pharmacological intervention for patients with gonorrhea. However, due to the remarkable ability of gonococcus...

Characterization of the Mechanistic Basis for the Cytotoxic Activity of Select Macrocyclic Natural Products against Glioblastoma Cells

Creator:: Serrill, Jeffrey D.
Abstract:: Natural products from both terrestrial and marine sources represent a significant source of novel drug leads, and have previously been developed into clinically-approved agents for the treatment of various human diseases. This work represents the biological characterization of the mechanistic basis for activity of several natural product structures in models...

Biosynthesis and modification of the antibiotic enduracidin

Creator:: Goebel, Neal C.
Abstract:: The continued propagation of antibiotic resistance requires the development of new therapeutics. The lipopeptide antibiotic enduracidin has demonstrated high activity against Gram-positive pathogens including methicillin-resistant Staphylococcus aureus. In addition to a lack of cross-resistance with existing antibiotic classes, enduracidin has no known transferrable resistance mechanism. The development of enduracidin as...

Biological characterization of coibamide A, a marine natural product from a Panamanian cyanobacterium

Creator:: Hau, Andrew M.
Abstract:: Coibamide A is a methyl-stabilized cyclic depsipeptide with a lariat side chain that was isolated from a marine cyanobacterium as part of an International Cooperative Biodiversity Groups program based in Panama. Previous testing of this potent and selective growth-inhibitory agent in the National Cancer Institute (NCI) in vitro 60 human...
