Figure Lengend Snippet: (A-B) Primary human foreskin fibroblasts were infected with VACV at high (MOI = 2, A) or low (MOI = 0.01, B) multiplicity of infection and treated with 10 μM ZW-2038, 40 μg/mL AraC (positive control), or vehicle control. Cell pellets were collected at 24 hpi (A) and 48 hpi (B) and infectious virus titers were quantified by plaque assay. (C) HFFs were infected with MOI = 0.01 of vLGluc in the presence of vehicle or a series of concentration of ZW-2038 or tecovirimat. Gaussia luciferase activities were measured at 24 hpi to determine the EC 50 value. Non-linear regression was used to calculate EC 50 values. (D) HFFs were treated with vehicle or a series of concentration of ZW-2038. CCK8 assay was performed at 24 h post treatment to calculate the CC 50 value. All data represent mean ± SD of at least three independent biological replicates. Statistical analysis was performed using one-way ANOVA with Dunnett’s post hoc test. ****p<0.0001.
Article Snippet: Tecovirimat was purchased from TargetMol and was dissolved in DMSO for all experiments.
