Cyclic amide bioisosterism: Strategic application to the design and synthesis of HCV NS5B polymerase inhibitors.
Bioorg.Med.Chem.Lett., 20:4614-4619, 2010

PubMed Abstract: Conformational modeling has been successfully applied to the design of cyclic bioisosteres used to replace a conformationally rigid amide bond in a series of thiophene carboxylate inhibitors of HCV NS5B polymerase. Select compounds were equipotent with the original amide series. Single-point mutant binding studies, in combination with inhibition structure-activity relationships, suggest this new series interacts at the Thumb-II domain of NS5B. Inhibitor binding at the Thumb-II site was ultimately confirmed by solving a crystal structure of 8b complexed with NS5B.
