An orally bioavailable pyridone derivative with antifibrotic, anti-inflammatory, and antioxidant activities; inhibits TGF-β1-stimulated increases in collagen type I, fibronectin, and Hsp47 expression in A549 lung cancer cells in a concentration-dependent manner; inhibits fibrosis and inhibits increases in collagen content, fibrocyte pool size, and the levels of chemokines CCL2 and CCL12 at 300 mg/kg in lung in a mouse model of pulmonary fibrosis induced by bleomycin; inhibits fibrosis and increases in hepatocyte apoptosis, lobular inflammation, and hepatic expression of the fibrosis-related genes Col1a1, Timp1, Tgfb1, Pdgfb, and Fgf2 in a mouse model of NASH at 280 mg/kg; inhibits NADPH-dependent lipid peroxidation in sheep liver microsomes and scavenges hydroxyl radicals (IC50s = ~6 and ~2.5 mM, respectively)
