| Description: | The Dengue virus type 2 strain New Guniea C (NG-C) and the Dengue virus type 4 strain H241 were purchased from ATCC (Manassas, Va.; item numbers VR-1584 and VR-1490, respectively). 24 hours prior to dosing, Huh-7.5 cells were plated in 96 well plates at a density of 1.5×105/ml in DMEM medium supplemented with 10% fetal bovine serum, 1% HEPES buffer, 1% Penicillin/Streptomycin and 1% non-essential amino acids (all Mediatech, Manassas, Va.). At the day of infection, serially diluted compounds were added to cells and incubated for 4 hours. After the end of the 4 hour pre-incubation period, cells were infected with either Dengue virus type 2 NG-C or Dengue virus type 4 H241. The virus inoculum was selected to cause 80-90% cytopathic effect in five to six days. Infected cells were incubated for five (NG-C) to six (H241) days at 37° C., 5% CO2. To develop the assay, 100 μl media was replaced with 100 μl CellTiter-Glo reagent (Promega, Madison, Wis.), and incubated for 10 min at room temperature. Luminescence was measured on a Victor X3 multi-label plate reader. Potential compound cytotoxicity was determined using uninfected parallel cultures. |
