General description

A cell-permeable antioxidant and a selective lipoxygenase (LOX) inhibitor (IC50 = 200 nM, 30 µM, and 30 µM for 5-LOX, 12-LOX, and 15-LOX, respectively) over cyclooxygenase (IC50 = 100 µM). Also shown to inhibit platelet-derived growth factor (PDGF)-stimulated DNA synthesis in Swiss/3T3 cells. A powerful hydroxy radical quencher.
