Sample concentration which caused 50% inhibition of TNF-induced NFκB activity treated with solvent (DMSO) only. N-Tosyl-L- phenylalanine-chloromethyl ketone (TPCK) and BAY-11 were used as a positive controls (IC50 = 3.8 and 2.0 μM, respectively).
Compounds 28, 30, 31, and 33 inhibited COX-1 with IC50 values of 0.87±0.04, 0.68±0.2, 2.8±0.67, and 2.0±0.57 μM, respectively. Compound 31 inhibited COX-2 with and IC50 value of 7.5±1.6 μM.
