GSK 256066 Trifluoroacetate

Research use only, not for human use.

A potent, selective PDE4 inhibitor with pIC50 of 11.5, 11.3, 11.4, and 11.9 for PDE4B, A, C, and D, respectively.

A potent, selective PDE4 inhibitor with pIC50 of 11.5, 11.3, 11.4, and 11.9 for PDE4B, A, C, and D, respectively; displays >380,000-fold selectivity over PDE1/23/5/6/7; inhibits TNFα production by lLPS-stimulated human peripheral blood monocytes with IC50 of 0.01 nM; inhibites LPS-induced pulmonary neutrophilia with ED50 of 1.1 ug/kg (aqueous suspension) and 2.9 ug/kg (dry powder formulation) in rats.COPD Phase 2 Discontinued.

GSK256066 Trifluoroacetate is an exceptionally high-affinity inhibitor of PDE4 designed for inhaled administration. GSK256066 Trifluoroacetate is highly selective for PDE4, with >380,000-fold versus PDE1/2/3/5/6 and >2500-fold against PDE7, and inhibits PDE4 isoforms A-D with equal affinity.GSK256066 Trifluoroacetate inhibits tumor necrosis factor α production by lipopolysaccharide (LPS)-stimulated human peripheral blood monocytes with IC50 of 0.01 nM.

GSK256066 Trifluoroacetate (0.3-100 μg/kg; intratracheally) inhibits the eosinophil number increased in the bronchoalveolar lavage (BAL) in a dose-dependent fashion, in lipopolysaccharide (LPS)- and ovalbumin (OVA)-induced acute pulmonary inflammation rat models..GSK256066 Trifluoroacetate inhibits LPS-induced pulmonary neutrophilia, and no emetic episodes are observed in ferrets. Animal Model:Male Brown Norway rats(180-200 g) Dosage: 0.3-100 μg/kg Administration: Intratracheally; 30 minutes before and 6 hours after ovalbumin challenge Result:Inhibited the increase in eosinophil number in the BAL in a dose-dependent fashion.
