Roflumilast | PDE4 inhibitor

Roflumilast (162401-32-3) is a potent and selective phosphodiesterase (PDE4) inhibitor, IC50=0.7, 0.9, 0.7, 0.2 nM for PDE4A1, PDE4A4, PDE4B1 and PDE4B2 respectively.1 Clinically useful agent for treatment of COPD.2 Improves sensory gating in humans3 and improves memory in rodent models4. Mimics calorie restriction effects via activation of AMPK/SIRT1 and protects against diabetic nephropathy.5 Reduces weight gain by increasing energy expenditure and improves glucose metabolism in mice.6
