The effect of NSAIDs on the viability of BxPC-3 and MIA PaCa-2 cells.
Notes: The most potent COX inhibitor meclofenamic acid showed the highest antiproliferative activity on both BxPC-3 and MIA PaCa-2 cell line (EC50 values after 72 h of drug exposure were 16,0 μM for BxPC-3 and, 43,5 μM for MIA PaCa-2 cells). The rank order of the activity of tested NSAIDs on BxPC-3 cell viability was as follows: meclofenamic acid>celecoxib>mefenamic acid>parecoxib>niflumic acid; on MIA PaCa-2 cell viability: meclofenamic acid>parecoxib>celecoxib>mefenamic acid=niflumic acid. Acetylsalicylic acid and salicylic acid had no effect on the viability of cancer cells (data not shown). The asterisks (*) indicate p<0.05.
Abbreviations: EC50, half maximal effective concentration; NSAIDs, non-steroidal anti-inflammatory drugs.
