    • Compounds were assayed in the fluorescence enzymatic assay using HCV NS3/4A 1a protease domain. Conditions: 0.75 nM enzyme (1a domain), 2 μM NS4A, 0.5 μM peptide substrate (Ac-DE-Dap(QXL520)-EE-Abu-ψ-[COO]AS-C(5-FAMsp)- NH2 is the FRET substrate purchased from Anaspec, Inc. San Jose, CA) in 50 mM HEPES, 20% sucrose, 5 mM DTT, and 0.05% NP-40. Wavelengths of 490 ex and 520 em were used on a Molecular Devices plate reader to measure initial rates. Compounds were also assayed for activity in the HCV genotype 1a and 1b subgenomic (NS3-NS5B) replicon model systems. The genotype 1b ET cell line is stably transfected with RNA transcripts harboring a I389luc-ubi-neo/NS3-3'/ET replicon with firefly luciferase-ubiquitin-neomycin phosphotransferase fusion protein and EMCV-IRES driven NS3-NS5B polyprotein containing cell culture adaptive mutations. The genotype 1a replicon is a stable cell line licensed from Apath LLC, modified to contain the firefly luciferase gene. The cells were grown in DMEM supplemented with 10% fetal calf serum (SAFC Biosciences, Lenexa, KS), 1× GlutaMax-1, penicillin (100 IU/mL)/streptomycin (100 μg/mL), 1× nonessential amino acids, and 500 μg/mL geneticin (all from Life Technologies, Bethesda, MD). The cells were plated at 5 × 103 cells/well in 384-well plates containing compounds. The final concentration of compounds ranged from 170 pM to 10 μM, with a final DMSO concentration of 1%. Luciferase activity was measured after 48 h by adding Steady-Glo (Promega, Madison, WI). Percent inhibition at each compound dose was calculated relative to the no compound control. EC50s were determined from an 11-point dose response curve and 3-fold serial dilutions for each compound, using a standard four parameter logistic fit equation.
