Exhibits anti-inflammatory and immunomodulatory effects by inhibiting lipid mediator and cytokine release from inflammatory cells and interfering with PDGF- and TGF-β1-induced proliferation and migration of vascular medial smooth muscle cells; inhibits PGD2 (IC50 = 0.1 mM), PGE2 (IC50 = ~1-20 µM), TXB2 (IC50 = ~10-50 µM), TGF-β1 (IC50 = ~100-200 µM), and IL-8 (IC50 = ~100 µM).
