Abstract In this study we investigated the effects of picolinic acid, a catabolite of L-tryptophan, on the production of L-arginine-derived reactive nitrogen intermediates in the murine macrophage cell line ANA-1. ANA-1 macrophages did not produce nitrite (NO2-) constitutively, but accumulated detectable levels of NO2- on exposure to IFN-gamma. Picolinic acid, although ineffective by itself, augmented IFN-gamma-induced NO2- production. The activity of picolinic acid was evident at 1 mM and reached its maximum at 4 mM. Picolinic acid also augmented the IFN-gamma-dependent expression of TNF-alph

Quinolinate phosphoribosyltransferase (QPRTase, E.C. 2.4.2.19) is considered to be a unique enzyme in that it is thought to catalyse two distinct chemical reactions. Both the transfer of a phosphoribosyl group from 5-phosphoribosyl-1- pyrophosphate onto the nitrogen of quinolinic acid and the subsequent decarboxylation of the intermediate to form nicotinic acid mononucleotide are thought to be catalysed by the QPRTase system. Analogues of quinolinic acid were designed as potential inhibitors of QPRTase. These contain acidic groups at the 2- and 3- positions but are unable to decarboxylate. How

Abstract:
Quinolinate phosphoribosyltransferase (QPRTase, EC 2.4.2.19) is an intriguing enzyme which appears to catalyse two distinct chemical reactions; transfer of a phosphoribosyl moiety from 5-phosphoribosyl-1-pyrophosphate to the nitrogen of quinolinic acid and decarboxylation at the 2-position to give nicotinic acid mononucleotide. The chemical mechanism of QPRTase is not fully understood. In particular, enzymatic involvement in the decarboxylation step is yet to be conclusively proven. QPRTase is neurologically important as it degrades the potent neurotoxin, quinolinic acid, implicated in disease

Abstract:
Characterising the geochemistry and speciation of major contaminant radionuclides is crucial in order to understand their behaviour and migration in complex environmental systems. Organic complexing agents used in nuclear decontamination have been found to enhance migration of radionuclides at contaminated sites; however, the mechanisms of the interactions in complex environments are poorly understood. In this work, radionuclide speciation and sorption behaviour were investigated in order to identify interactions between four key radionuclides with different oxidation states (Cs(I) and Sr(II)

<p>Diabetes mellitus is one of the most threatening epidemics of modern times with rapidly increasing incidence. Vanadium and peroxovanadium compounds have been shown to exert insulin–like actions and, in contrast to insulin, are orally applicable. However, problems with side–effects and toxicity remain. The exact mechanism(s) by which these compounds act are not yet fully known. Thus, a better understanding of the aqueous chemistry of vanadates and peroxovanadates in the presence of various (bio)ligands is needed.</p><p>The present thesis summarises six papers dealing mainly with aqueous spec
