The hepatitis C virus (HCV) NS5B polymerase is an attractive target for the development of novel and selective inhibitors of HCV replication. In this paper, the design, synthesis, and preliminary SAR studies of novel inhibitors of HCV NS5B polymerase based on the structure of tegobuvir have been described. The efforts to optimize the antiviral potency and reduce the treatment side effects with respect to genotype 1b resulted in the discovery of compound 3, which exhibited an EC50 of 1.163 nM and a CC50 >200 nM in a cell-based HCV replicon system assay. Additionally, testing for inhibition of the hERG channel showed a marked improvement over tegobuvir and the pharmacokinetic properties of compound 3 indicated that it was worthy of further investigation as a non-nucleoside inhibitor of HCV NS5B polymerase.

Synthesis of filibuvir. Part III. Development of a process for the reductive coupling of an aldehyde and a β-keto-lactone
Ide, Nathan D.,Ragan, John. A.,Bellavance, Gabriel,Brenek, Steve J.,Cordi, Eric M.,Jensen, Grace O.,Jones, Kris N.,France, Danny La,Leeman, Kyle R.,Letendre, Leo J.,Place, David,Stanchina, Corey L.,Sluggett, Gregory W.,Strohmeyer, Holly,Blunt, Jon,Meldrum, Kevin,Taylor, Stuart,Byrne, Ciaran,Lynch, Denis,Mullane, Sandra,O'Sullivan, Maria M.,Whelan, Marcella

Development of a reductive coupling of a β-keto-lactone and an aldehyde is described, in which the Hantzsch ester serves as an inexpensive and convenient reducing agent. Structural features in the β-keto-lactone rendered standard reductive coupling conditions ineffective, requiring development of a specific addition and temperature protocol. Identification of one of the reactants as Ames positive required a single-digit parts per million control strategy for this impurity in the final active pharmaceutical ingredient (API).
