Etodolac (Lodine) is a selective Cyclooxygenase-2 (COX-2)?inhibitor with an IC50 of 53.5 nM.? Etodolac, a non-steroidal anti-inflammatory drug (NSAID), has been reported to treat osteoarthritis and rheumatoid arthritis.
Etodolac was able to abolish the cell size decrease and block caspase-3/7 activity in TNFα-induced isolated rabbit articular chondrocytes [1]. However, studies have shown that etodolac at 24h could induce cell death in human malignant rhabdoid tumor cells (FRTK-1) in a dose-dependent manner. Additionally, etodolac has shown to increase caspase-8, -9 and -3 activity 3 at 24 or 48 h in FRTK-1 [2].
