We describe the research that led to the discovery of compound 40 (ruzasvir, MK-8408), a pan-genotypic HCV nonstructuralprotein5A (NS5A) inhibitor with a “flat” GT1 mutant profile. This NS5Ainhibitor contains a unique tetracyclic indole core while maintaining the imidazole–proline–valine Moc motifs of our previous NS5Ainhibitors. Compound 40 is currently in early clinical trials and is under evaluation

We describe the impact of proline modifications, in our tetracyclic-indole based series of nonstructuralprotein5A (NS5A) inhibitors, to their replicon profiles. This work identified NS5Ainhibitors with an improved and flattened resistance profiles.

As part of an ongoing effort in NS5A inhibition at Merck we now describe our efforts for introducing substitution around the tetracyclic indole core of MK-8742. Fluoro substitution on the core combined with the fluoro substitutions on the proline ring improved the potency against GT1a Y93H significantly. However, no improvement on GT2b potency was achieved. Limiting the fluoro substitution to C-1 of
