Table 2. IC50 Values of Test Compounds in the PGE2/PGD2 and LTB4 Assays.
Inhibition of COX pathway as determined by LC–MS/MS analyses of the combined production of COX-derived PGD2 and PGE2 in RBL-1 cells upon stimulation with arachidonic acid in the presence or absence of test compounds.
Inhibition of 5-LOX pathway as determined by LC–MS/MS analyses of the production of 5-LOX-derived LTB4 in RBL-1 cells upon stimulation with arachidonic acid in the presence or absence of test compounds. *The data represent the calculated IC50 values and associated 95% confidence intervals as determined from triplicate samples at each concentration after a sigmoidal curve fit using GraphPad Prism software.
