This disclosure concerns novel compounds of Formula (I) as defined in the specification and compositions comprising such novel compounds. These compounds are useful antiviral agents, especially in inhibiting the function of the NS5A protein encoded by Hepatitis C virus (HCV). Thus, the disclosure also concerns a method of treating HCV related diseases or conditions by use of these novel compounds or a composition comprising such novel compounds.

Particles comprising a branched polymer and either a block copolymer or a linear dendritic hybrid represent a category of useful materials. They may be used in for example drug delivery applications. They may be prepared by a method comprising the steps of: dissolving the branched polymer and block copolymer or linear dendritic hybrid, and optionally other component(s),in a solvent to form a solution; adding said solution to a different liquid; and removing said solvent to form a dispersion of co-precipitated particles.

Diastereoselective oxidative coupling of ketones through a silyl bis-enol ether intermediate by anodic and photocatalytic oxidation is reported. These methods provide several 1,4-diketones in good yields without the need for stoichiometric metal oxidants. The strategic use of a silicon tether enables the coupling of both aromatic and aliphatic ketones as well as the synthesis of quaternary centers

Branched polyesters carrying dendrons are a useful class of nanomaterials which exhibit good handling properties and stability, can degrade to a high extent, and are effective encapsulation materials. They can be used to make nanoprecipitated particles which may for example be used in therapy. Furthermore, these materials can be synthesised by economical and tailorable processes. The materials can be prepared by the ring-opening polymerisation (ROP) of monofunctional lactone monomers and difunctional lactone monomers, using dendron initiators.
with one or two equivalents of -butyllithum and various dienes (furans, pyrroles, cyclopentadienes, fulvenes) to form mono- or bis-cycloadducts. Highly substituted arenes can be obtained by removing the oxygen or nitrogens bridges from the furan or pyrrole adducts. By choice of conditions, two identical or two different rings can be fused to the di-aryne epuivalent. Improved short syntheses of permethylnaphthalene
