Himeradine A : synthetic efforts towards himeradine A and related natural products, a Michael reaction focused approach

Creator:: Collett, Nathan D.
Abstract:: Lycopodium alkaloids have generated enormous amounts of interest from the scientific community, both as synthetic targets and for their medicinal properties. Herein is described work towards a unifying approach to large segments of the Lycopodium family. An organocatalyzed intramolecular heteroatom Michael reaction method, for the construction of piperidine and piperizine...

Theoretical and experimental factors affecting the accuracy and precision of atomic absorption measurements

Creator:: Bower, Nathan Wayne
Abstract:: A procedure for evaluating the precision of atomic absorption measurements is presented and applied to 21 elements under varying instrumental conditions. The experimental relative standard deviations (RSD's) in absorbance obtained from repetitive measurements made with a high resolution voltmeter and on-line computer, are compared to those predicted by a recently...

From electrophoresis to dielectrophoresis: designing, fabricating, and evaluating an electroformed ratchet type microfluidic dielectrophoresis device

Creator:: Gonzalez, Carlos F.
Abstract:: Dielectrophoresis (DEP) is a separation method in which a non-uniform electric field is used to induce a dipole moment in a suspended particle. If the polarization of the particle is greater than that of the suspending medium, the particle will move towards the region of higher field strength (positive DEP);...

Hydrogen/deuterium exchange mass spectrometry as a technology platform for studying conformational dynamics in large protein complexes

Creator:: Nirudodhi, Sasidhar N.
Abstract:: Proteins are essential to all biological systems. Proteins participate in numerous cellular processes by interacting with other proteins, other metabolites and membranes in a dynamic environment. Studying the structural and conformational properties of proteins in the solution phase is necessary to understand their protein folding and interaction dynamics. This research...

Active site studies and design of ligands for affinity column separation of 2,5-dihydroxyacetanilide epoxidase (DHAE) I and II

Creator:: Allen, Scott E.
Abstract:: A series of compounds, 7-8 and 20-25, were tested as competitive inhibitors of 2,5-dihydroxyacetanilide epoxidase I (DHAE I) and DHAE II. A Hammett plot was constructed for each enzyme to determine the effect of electron density on inhibition. DHAE I gave a linear, highly correlated plot (r²=0.91) that signifies the...

Enzymatic studies of the prenatal chick, with special reference to the multibple forms of liver soluble NADP-linked isocitric dehydrogenase

Creator:: Cheung, Geoffrey Peter
Abstract:: Levels of activity of glucose-6-phosphate- , 6-phosphogluconate- , and isocitric- dehydrogenase were measured in the soluble and particulate fractions of heart, brain and liver at several ages throughout the development of the chick embryo. Compared to isocitric dehydrogenase, levels of glucosesphosphate- , and 6-phosphogluconate- dehydrogenase are generally low. This suggests...

A unified approach for the total synthesis of C₁₀-functionalyzed Lycopodium alkaloids

Creator:: Saha, Mrinmoy
Abstract:: Lycopodium alkaloids have shown widespread and noteworthy biological activity, consisting of over 250 known natural products. Moreover, their structural complexity and diversity have attracted considerable attention from numerous laboratories including our own. Recently, we have developed a unified approach that would provides access to numerous, previously unprepared C₁₀-functionalized lycopodium alkaloids....

Purification and characterization of a cytoplasmic apyrase plumules of Pisum sativum

Creator:: Nishikawa, Alfred Hirotoshi
Abstract:: The 105,000 x g supernatant fluid (S[subscript HS]) from extracts of pea seedlings (Pisum sativum, var. Alaska) etiolated for 60 hours yielded a very potent adenosine triphosphatase activity. This activity was designated as an apyrase when the reaction stoichiometry indicated that adenosine triphosphate (ATP) was hydrolyzed to adenosine monophosphate (AMP)...

Addition of hydrogen bromide to unsymmetrical olefins

Creator:: Rogers, Charles Junior
Abstract:: In this investigation the addition of hydrogen bromide to 3-methylcyclohexene has been studied in order to see if the theory of hyperconjugation could be extended to include olefins of this type. Since the olefin has an equal number of hydrogens on both carbons carrying the double bond, a mixture of...
