Synthesis Of Novel Antimycobacterials And A Fluorescent Sensor For Simple Carbohydrates, Brian Thomas Walker
Synthesis Of Novel Antimycobacterials And A Fluorescent Sensor For Simple Carbohydrates, Brian Thomas Walker
Theses and Dissertations
Cell surface carbohydrates play an important role in a wide variety of biological processes such as inflammation, tumor metastasis, and viral and bacterial infection. The goal of our research has been two-fold. The first objective was the synthesis of antimycobacterial compounds. A mannose containing tetrasaccharide from the mannan core of lipoarabinomannan (LAM) of Mycobacterium tuberculosis has been synthesized using α-D-methylmannopyranoside as starting material and Koeings-Knorr reactions to couple saccharides. The synthesis was completed in nine steps and in 14% total yield. This compound should be useful in competitive inhibition studies with macrophages or as an immunological marker. We have successfully …
Effect Of Nitric Oxide On Oxygen Consumption Of Skeletal Muscle, Christina Lyn Cox
Effect Of Nitric Oxide On Oxygen Consumption Of Skeletal Muscle, Christina Lyn Cox
Theses and Dissertations
Mammalian cells require a continuous and sufficient supply of oxygen to carry out their functions. The oxygen pathway has an overall direction taking O2 from the air to the mitochondria, which is a result of the mitochondrial O2 consumption (VO2) NO various effects on the mitochondria: at low concentrations for short periods NO specifically and irreversibly inhibits cytochrome c and reversibly inhibits cytochrome c oxidase, to decrease VO2. Thus, NO can modulate VO2 of skeletal muscle. The purpose of the present study was to measure VO2 of the rat spinotrapezius muscle under conditions of altered NO. The methods used provide …
