Phosphatidylinositol 4-kinase III beta is a cellular lipid kinase pivotal to pathogenesis of various RNA viruses. These viruses hijack the enzyme in order to modify the structure of intracellular membranes and use them for the construction of functional replication machinery. Selective inhibitors of this enzyme are potential broad-spectrum antiviral agents, as inhibition of this enzyme results in the arrest of replication of PI4K III beta-dependent viruses. Herein, we report a detailed study of novel selective inhibitors of PI4K III beta, which exert antiviral activity against a panel of single-stranded positive-sense RNA viruses. Our crystallographic data show that the inhibitors occupy the binding site for the adenine ring of the ATP molecule and therefore prevent the phosphorylation reaction.
Evaluation of the 2-Substituent Effect on the Reactivity of the 8-Haloimidazo[1,2-<i>a</i>]pyridine Series towards Suzuki-Type Cross-Coupling Reaction
The purpose of this work was to complete a general study that we initiated on the influence of a 2-substitution on the reactivity of 8-haloimidazo[1,2-a]pyridines towards a Suzuki cross-coupling reaction, using conventional reactants in order to obtain easily performed (hetero)arylation methods with a high degree of flexibility with regard to functional groups.

as solubility, are important when prioritising compounds for progression on a drug discovery project. There is limited literature around the systematic effects of core changes on thermodynamic solubility. This work details the synthesis of nitrogen containing 6,5-bicyclic heterocyclic cores which are common scaffolds in medicinal chemistry and the analysis of their physicochemical properties, particularly
