    Product Description

    GSK256066 is a potent phosphodiesterase 4 (PDE4) inhibitor (IC50s = 4.9, 3.2, 3.8, and 1.1 pM for PDE4A, PDE4B, PDE4C, and PDE4D, respectively).1 It is greater than 380,000-fold selective for PDE4 over PDE1-3, -5, and -6 and greater than 2,500-fold selective over PDE7. GSK256066 inhibits LPS-induced TNF-α production in human peripheral blood monocytes (IC50 = 0.01 nM) and human whole blood (IC50 = 126 pM). Intratracheal administration of GSK256066 inhibits LPS-induced pulmonary neutrophilia in rats (ED50 = 1.1 µg/kg). It inhibits ovalbumin-induced pulmonary eosinophilia in rats (ED50 = 0.4 µg/kg) and LPS-induced pulmonary neutrophilia in ferrets (ED50 = 18 µg/kg).2

    WARNING This product is not for human or veterinary use.
