Abstract:
ABSTRACT We studied the biochemical mechanisms associated with inhibition and resistance to a 4,5-dihydroxypyrimidine carboxylate that inhibits the hepatitis C virus (HCV) RNA-dependent RNA polymerase NS5B. On the basis of the structure of the pharmacophore, it has been suggested that these compounds may act as pyrophosphate (PPi) mimics. We monitored nucleotide incorporation events during the elongation phase and showed that the polymerase activity of wild-type NS5B was inhibited by the dihydroxypyrimidine at a 50% inhibitory concentration (IC50) of 0.73 μM.

Les virus de l'ordre des Bunyavirales constituent un problème de santé publique en raison du manque d’options thérapeutiques et de leur répartition mondiale. La protéine L gouvernant le système de réplication virale possède une activité endonucléase responsable du mécanisme du vol-de-coiffe permettant la transcription. Cette enzyme clé a été identifiée comme une cible thérapeutique de choix pour développer des antiviraux. Son mécanisme d’hydrolyse de l’ARN médié par les ions Mg2+ permet de développer des inhibiteurs chélateurs de métaux de type dicéto-acide (DCA). La synthèse guidée par la cib

碩士<br>國立臺北科技大學<br>化學工程研究所<br>101<br>This thesis focuses on the preparation of based metal–organic frameworks based on nucleobases via a self-assembly strategy. Two uracil-derivatives, 4,6-dihydroxypyrimidine (H2dhp) and 2,4-dihydroxypyrimidine-5-carboxylic acid (H3dhpca), were selected for use as potential organic ligands. The assembly of CaII, NiII ions with 4,6-dihydroxypyrimidine (H2dhp) in water or alcohol at ambient temperature led to the formation of the discrete molecule [Ni(Hdhp)2(H2O)4] (1) and a 2D metal–organic frameworks {[Ca(Hdhp)2(H2O2)]•THF}n (2).
