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....

Synthesis of novel ambifunctional atropisomeric 2,2',6,6'-tetrasubstituted biphenyls and investigation of their properties and organocatalytic activity

Creator:: Sephton, Mark Alan
Abstract:: Ambifunctional axially chiral 2,2',6,6'-tetrasubstituted biphenyls containing nucleophilic (or basic) functional groups juxtaposed with hydrogen-bond donors were synthesized and their properties studied. Applications for the prepared biaryls as potential organocatalysts for enantioselective carbon-carbon bond forming reactions were examined. Processes investigated included: aldol, Michael, nitroaldol (Henry), and Baylis-Hillman reactions. The novel amidoamine...

A stereochemically controlled approach to the morphine alkaloids: racemization of 8,9-benzo-4,5-dihydro-6,7-pyrido[4,3-d] oxanin-3(2H)-ones

Creator:: Runyan, Mark T.
Abstract:: A method for the control of absolute stereochemistry in morphine syntheses has been demonstrated by the resolution and efficient racemization of the advanced morphine precursor , 9-methoxy-3-methyl-5,6-dihydro-3H-benzofuro[3,2-e]isoquinoline- 7(7aH)-one, I. This was accomplished by the facile coversion of optically resolved I to its ring opened form, 5,6,7,8-tetrahydro-10-methoxy-3-methyl-7-oxo[1]benzoxonino[ 6,7-c]pyridinium tosylate, II, (Equation...

Part I : development and application of an arsenic speciation technique using ion-exchange solid phase extraction coupled with GFAAS ; Part II : investigation of zinc amalgam as a reductant

Creator:: Bos, Mark C.
Abstract:: Two related techniques, based upon ion-exchange solid phase extraction, have been developed for the determination of arsenic speciation. The inorganic arsenic species arsenite (As(III)) and arsenate (As(V)) are separated by anion-exchange and detected with graphite furnace atomic absorption spectrophotometry (GFAAS) with a nickel matrix modifier. The first separation technique, which...
