Synthesis of silyloxyacrolein for [4+3] cycloaddition and preparation of carbonate closomer
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Followed by Funk's method, I synthesized silyloxyacroleins and used them as dienophiles to react with different dienes in [4+3] cycloaddition reaction. ...
Variable-temperature [superscript 1]H-NMR and AB initio study of 5-amino-imidazole-4-carboxamide (AICA) : competing paths for amide-H scrambling
(University of Missouri--Columbia, 2008)
5(4)-aminoimidazole-4(5)-carboxamide (AICA and TAICA) is an important precursor for the synthesis of purines in general and of the nucleobases adenine and guanine in particular. Biotic nucleobase synthesis has been studied ...
The synthesis and characterization of 1,1'-disubstituted ferrocene imine Schiff base ligand systems for use as potential environmental heavy metal cationic sensors
(University of Missouri--Columbia, 2008)
Heavy metals in the environment such as Cd, Hg and Pb are toxic to life forms. They can enter the ecological system through both natural and industrial sources. By developing chemical sensors that can detect these metals, ...
Biologically relevant chemistry of sulfur heterocycles : from redox regulation of PTP1B to the biological activity of s-deoxy leinamycin
(University of Missouri--Columbia, 2008)
Protein tyrosine phosphatase 1B (PTP1B) is an important member of protein tyrosine phosphatase (PTPs) family that shares a conserved catalytic cysteine thiol residue. PTP1B acts as a negative regulator of insulin mediated ...
Oxidative DNA damage by 1-hydroxyphenazine, virulence factor of Pseudomonas aeruginosa : towards a molecular understanding of the bacterial virulence factor 1-hydroxyphenazine
(University of Missouri--Columbia, 2008)
1-Hydroxyphenazine is a secondary metabolite and virulence factor of Pseudomonas aeruginosa. This organism colonizes the airways of the patients of cystic fibrosis and causes progressive destruction of the airways. It is ...
Spectroscopic investigations of the beta-amyloid peptide
(University of Missouri--Columbia, 2008)
The focus of this project is two-fold: examining the native structures of three different fragments of the beta-amyloid (A[beta]) peptide, and attempting to overcome some of the difficulties encountered in such an examination. ...
High valent uranium dioxo and imido complexes : synthesis and structure
(University of Missouri--Columbia, 2008)
Early actinide elements have attracted considerable attention in recent years due to the need for rigorous advancements in spent nuclear fuel recycling and remediation technologies, and for their emerging versatility in ...
Chemical mechanisms underlying the medicinal activity of metabolically-activated N-oxide antitumor agents
(University of Missouri--Columbia, 2008)
Tirapazamine (TPZ) belongs to a new class of bio-reductively activated hypoxiaselective anti-cancer agents and is currently undergoing in various clinical trials including Phase I, II and III. Anti-cancer activity of TPZ ...
Copper (I) coordination networks synthesized with solid-solid reactions
(University of Missouri--Columbia, 2008)
The use of solid-solid reactions in the development of one-, two-, and three dimensional Cu(I) coordination networks are discussed. The solid-solid reactions were monitored by a variety of instrumental techniques to achieve ...
Synthesis and evaluation of [105]Rhodium (III) complexes of phosphine chelate systems
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] [Superscript 105]RH has attractive nuclear and chemical properties to be investigated as a nuclide for development of potential radiopharmaceuticals. ...
Spectroscopic investigations of acrylodan dye interactions with poly(amidoamine) and poly(propyleneimine) dendrimers
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The novel molecular architecture of dendrimers facilitates use in many applications. Using the solvatochromic probe phenol blue, the first direct ...
Spatially resolved and bulk zinc analysis in biological samples of patients at different stages of Alzheimer's disease by high resolution inductively coupled plasma mass spectrometry
(University of Missouri--Columbia, 2008)
One hypothesis that has gained considerable attention in the pathogenesis of Alzheimer's disease (AD) is trace element toxicity, and various elements, including zinc, have become the foci of renewed interest. The first ...
Spectroscopic investigations of dendritic polymers as molecular containers
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Previous research has shown the fluorescent probe phenol blue will associate with the dendritic polymers polypropyleneimine (PPI) and polyamidoamine ...
