Indomethacin, an anti-inflammatory agent, inhibits Cox-1 and Cox-2 (cyclooxygenases) with selectivity for Cox-1 (IC50 of 230 nM) over Cox-2 (IC50 of 630 nM). Additionally, Indomethacin displays adipogenic actions via binding and activation of PPARγ (peroxisome proliferator-activated receptor γ), a ligand-activated transcription factor known to play an important role in adipogenesis. Other studies show Indomethacin to stabilize cholesterol-dependent nanoclusters and enhance phase separation in biological membranes, which could consequentially effect plasma membrane assembled cell signaling cascades. Indomethacin is an activator of PPAR α.
