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...

Studies towards the total syntheses of (+)-phomactins A, D and G

Creator:: Schwartz, Keith D.
Abstract:: Studies towards the total synthesis of (+)-Phomactin A (1), D (6), and G (9), fungal metabolites with unique molecular architecture and pronounced biological activity, are described. These studies resulted in the synthesis of advanced intermediates 354 and 356, which contain all of the carbon atoms of 1, 6 and 9....

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...

Studies Toward the Synthesis of Natural Product Scaffolds

Creator:: 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...

Evaluation of Bacterial F1FO-ATPase Inhibitors for Synergistic Effects

Creator:: Heppe, Kenan G.
Abstract:: F1FO-ATP synthase targeting antimicrobials apoptolidin 1 (A1), (+)-erythromefloquine, and oligomycin were tested in vitro for synergistic minimum inhibitory concentrations against Staphylococcus aureus. Synergy was strictly defined as inhibition by at most 25% the MIC of each participating drug. Ampicillin, with an MIC of 0.8 ug/mL, served as a negative control....

Improvements in synthesis and response techniques of ion-selective sensors

Creator:: Pylypiuk, Nataliia
Abstract:: Two improvements to the established procedures for synthesis and response detection of ion-selective optical sensors (optodes) were introduced. The first improvement addresses the drawback of organic dye (optode-localized chromoionophore) photobleaching. This positively impacts fluorescence response and allows for (1) direct measurement of hydrogen ion activity upon binding with the dye,...

Generating and using terahertz radiation to explore carrier dynamics of semiconductor and metal nanostructures

Creator:: Jameson, Andrew D.
Abstract:: In this thesis, I present studies in the field of terahertz (THz) spectroscopy. These studies are divided into three areas: Development of a narrowband THz source, the study of carrier transport in metal thin films, and the exploration of coherent dynamics of quasi-particles in semiconductor nanostructures with both broadband and...

Part I: Synthesis and evaluation of synosutine as an inhibitor of serotonin, norepinephrine, and dopamine transporters Part II: Asymmetric approach to the tetracyclic core of neomangicol A

Creator:: Juniku, Rajan B.
Abstract:: Part I: Racemic and asymmetric syntheses of a new substance with prospective antidepressant properties were achieved. In vitro assays with synthetic racemates (±)-25 and (±)-26 suggested that the former is a relatively selective inhibitor of serotonin transporter whereas the latter is a more balanced inhibitor of both serotonin and norepinephrine...

Studies toward the total synthesis of sanglifehrin A

Creator:: Suttisintong, Khomson
Abstract:: Studies toward synthesis of subunits of sanglifehrin A, an immunosuppressant featuring a highly substituted [5,5]-spirolactam moiety as well as a 22-membered macrocycle are described. The macrolactone contains a peptidic backbone characterized by an unusual [beta]-substituted (S)-piperazic acid and (S)-m-hydroxyphenylalanine units. These studies resulted in the synthesis of advanced intermediate 358...

Terahertz transmission & spectroscopy of vertically grown multi-walled carbon nanotube forests

Creator:: Maizy, Louis
Abstract:: In this thesis, I present studies in the field of terahertz [THz] spectroscopy. It covers both the generation and detection of ultra-fast broadband THz pulses, as well as the transmission properties of vertically grown multi-walled carbon nanotube forests [MWCNTs]. We have found that these vertically grown MWCNTs respond strongly to...
