| Description: | On day 1, 50 μL of each test compound dilution in duplicates or a vehicle control was added to each well of a 96-well plate followed by addition of 150 μL of HEK-Blue hTLR2 cell suspension (1×105 cells/well) and incubated at 37° C./5% CO2 for 2 h. Next, 50 μL of an approximate 3×EC50 concentration of each agonist (Pam2CSK4 or Pam3CSK4) was added to the wells containing test compounds or the vehicle control. The plates were then incubated at 37° C./5% CO2 for 18 h. For each assay run, non-treated HEK-Blue hTLR2 cells were treated with serial dilutions of agonists to determine EC50 values for the respective run. On day 2, secreted alkaline phosphatase (SEAP) activity was detected in cell culture supernatants. In brief, 20 μL was collected from each well and transferred to a 96-well plate. Next, 200 μL of Quanti-Blue detection reagent was added to each well. Plates were incubated at room temperature for 15 min and SEAP activity was assessed by spectrophotometer OD reading at 655 nm. Table A shows the activities of the compounds tested in HEK cells using Pam2CSK4 and Pam3CSK4 as agonists. The activities of the compounds against Pam2CSK4 and Pam3CSK4 are presented as IC50 values which were defined as concentrations of the compounds where percent inhibition of the signal induced by agonist is equal to 50%. IC50 values were calculated based on 8-point dilutions for each compound. |
