Fig 2. The clemizole-SCH503034 combination is synergistic across genotypes and in HCV-infected cells.
The antiviral effect of the clemizole-SCH503034 combination was determined using (A) genotype 1b luciferase reporter-linked replication assays, and (B) focus formation assays in cells infected with cell culture-grown HCV. Assays were performed following 72hr of treatment. Differential surface plot at the 95% confidence level are shown (generated using MacSynergyII). Peaks above the theoretical additive plane indicate synergy, whereas depressions below it indicate antagonism. The colors indicate the level of synergy/antagonism.
