Biochem/physiol Actions

GSK256066 is a reversible and cAMP-competitive phosphodiesterase 4 (PDE4) inhibitor that targets all PDE4 subtypes with high affinity (IC50 = 53.7 pM against 2 nM [3H]-rolipram for binding HRBS in rat brain cytosol), potency and selectivity (pIC50 ≥11.31/11.5/11.42/11.94 against PDE4A/B/C/D vs. pIC50 = 5.73/5.92/5.93/5.39/5.28/8.11 against PDE1/2/3/5/6/7 by SPA assays). GSK256066 effectively inhibits LPS-induced TNFα production from human whole blood and isolated PBMCs (pIC50 = 126 and 10 pM, respectively) in vitro and acute pulmonary neutrophilia in rats in vivo (ED50 = 1.1 μg/kg, administered intratracheally 2 hrs priror to LPS). GSK256066 is shown to be more potent than Cilomilast (SB-207499) and Roflumilast in both cell-free and cell-based assays.

Oral phosphodiesterase (PDE) 4 inhibitors have demonstrated clinical efficacy in chronic obstructive pulmonary disease and asthma. Preclinical and clinical investigation of inhaled PDE4 inhibitors is ongoing. 6-({3-[(Dimethylamino)carbonyl]phenyl}sulfonyl)-8-methyl-4-{[3-methyloxy)phenyl]amino}-3-quinolinecarboxamide (GSK256066) is an exceptionally high-affinity and selective inhibitor of PDE4 designed for inhaled

CD8 lymphocytes play an important role in the pathogenesis of COPD. Corticosteroids and phosphodiesterase 4 (PDE4) inhibitors are anti-inflammatory drugs used for COPD treatment. Little is known of the combined effect of these drugs on COPD CD8 cells. We studied

Crystallography driven optimisation of a lead derived from similarity searching of the GSK compound collection resulted in the discovery of quinoline-3-carboxamides as highly potent and selective inhibitors of phosphodiesterase 4B. This series has been optimized to GSK256066, a potent PDE4B

Oral phosphodiesterase (PDE) 4 inhibitors such as roflumilast have established the potential of PDE4 inhibition for the treatment of respiratory diseases. However, PDE4 inhibitor efficacy is limited by mechanism-related side effects such as emesis and nausea. Delivering the inhibitor by
