Licofelone (ML-3000) is a dual COX/5-lipoxygenase (5-LOX) inhibitor (IC50=0.21/0.18 μM, respectively) for the treatment of osteoarthritis. Licofelone exerts anti-inflammatory and anti-proliferative effects. Licofelone induces apoptosis, and decreases the production of proinflammatory leukotrienes and prostaglandins.
