In vitro, telaprevir selects subtype-specific resistance pathways for hepatitis C virus GT-1a and GT-1b, as described to have occurred in patients. In GT-1a, the HCV-796 resistance mutation C316Y has low replication capacity (7%) that can be compensated for by the

In the course of investigating the propensity of aromatic acids to react with selected nucleophiles, we came across an interesting difference in yields for two structurally similar thiophene carboxylic acids. Given that these yields were consistent across more than 40

A stereocontrolled synthesis of α-amino-α'-alkoxy ketones is described. This pH-neutral copper(I) thiophene-2-carboxylate (CuTC)-catalyzed cross-coupling of amino acid thiol esters and chiral nonracemic α-alkoxyalkylstannanes gives α-amino-α'-alkoxy ketones in good to excellent yields with complete retention of configuration at the α-amino- and

Further SAR studies on the thiophene-2-carboxylic acids are reported. These studies led to the identification of a series of tertiary amides that show inhibition of both HCV NS5B polymerase in vitro and HCV subgenomic RNA replication in Huh-7 cells. Structural
