Biological Activity

Indomethacin is a potent and nonselective inhibitor of COX1 and COX2, with IC50s of 18 nM and 26 nM for human COX-1 and COX-2, respectively, in CHO cells. Indomethacin inhibits lipopolysaccharide (LPS)-induced PGE2 production (COX-2) in a human whole blood assay with a potency (IC50=0.68±0.17 μM), and suppresses coagulation-induced TXB2 production (COX-1) (IC50=0.19±0.02 μM). Indomethacin blocks COX-1 with an IC50 of 20±1 nM in U937 cell microsomes at a low arachidonic acid concentration (0.1 μM).

Cell Experiment
Cell lines GES-1 cells
Preparation method Viability assay
Cellular proliferative viability was detected using the MTT assay. Briefly, GES-1 cells (1 × 10^5 cells/well) were seeded in a 96-well plate to adhere for 24 h, and then pretreated with oleanolic acid, ursolic acid, 3-O-acetyl ursolic acid, betulinic acid, 3-O-acetyl pomolic acid, maslinic acid, and TA (1.563, 3.125, 6.25, 12.5, 25, and 50 µM) for 6 h, then continued or treated with indomethacin (IND) in the concentration of 700 μM for 18 h. Next MTT solution (20 µL, 5 mg/mL) was added to each well and incubated for 4 h at 37 °C. Then the medium was discarded and 150 mL DMSO was added to dissolve the formazan crystals. Finally, viable cells were detected by measuring absorbance at 570 nm using a Microplate Reader.
