PDE4 3.2 pM (IC50) |
GSK256066 is an exceptionally high-affinity inhibitor of PDE4 designed for inhaled administration[1].
?
GSK256066 is highly selective for PDE4, with >380,000-fold versus PDE1/2/3/5/6 and >2500-fold against PDE7[1].
?
GSK256066 inhibits PDE4 isoforms A-D with equal affinity (PDE4B: pIC50≥ 11.5, PDE4A: pIC50≥11.31, PDE4C: pIC50≥11.42, PDE4D: pIC50≥11.94)[1].
?
GSK256066 inhibits TNF-α production by lipopolysaccharide (LPS)-stimulated human peripheral blood monocytes with IC50 of 0.01 nM[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
? GSK256066 also inhibits LPS-induced increases in exhaled nitric oxide (ED50=92 μg/kg)[2].
? GSK256066 inhibits pulmonary eosinophilia in rats exposed to ovalbumin (ED50=0.4 μg/kg)[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
-
Animal Model:Male Brown Norway rats (180-200 g)[2]
