become the targets for HCV chemotherapy. The current treatment involves pegylated interferon-α/ribavirin-based treatment and a combination of direct-acting antivirals. NS5B is a critical enzyme for the replication of HCV RNA and is an interesting target for the screening and design of small molecule inhibitors to interfere in the HCV viral replication. Methods: Screening of a library of compounds in a replicon

The present invention relates to a process for the preparation of value added chemicals such as ethyl levulinate from a glucose or other sugars catalyzed by a mixture of a Lewis and a Bronsted acid catalyst.
A series of seven symmetric difuryl-diynes were synthesized by a route delivering an anti-configurated product as the major product. The gold-catalyzed conversion of the individual anti- and syn-diastereomers was investigated. The anti-diastereomer in a desymmetrization reaction chemoselectively delivered dihydroindenediols with a furyl and a 2-oxopropyl side chain. The syn-diastereomer was completely converted into oligomeric/polymeric material. Thus, it was not necessary to separate the minor amount of the syn-diastereomers from the product mixtures in order to isolate the dihydroindenediols.
A polymer scale deposition preventive agent for use in polymerization of a monomer having an ethylenically unsaturated double bond, comprising an alkali metal salt and/or ammonium salt of a sulfonation product of a condensate comprising (A) an aromatic amine compound and (B) an aldehyde compound as essential condensation components. Deposition of polymer scale in a polymerization vessel can be effectively prevented, not only on the areas in the liquid-phase region but also on the areas around the interface between the gas phase and the liquid phase. Products such as sheets formed from the polymeric product have very few fish eyes, and have very little initial discoloration, and therefore are of high quality. The use of the agent makes it unnecessary to remove polymer scale for every polymerization run, thereby improving productivity.
