AMG-548 dihydrochloride, an orally active and selective p38α inhibitor (Ki=0.5 nM), shows slightly selective over p38β (Ki=36 nM) and >1000 fold selective against p38γ and p38δ. AMG-548 dihydrochloride is also extremely potent in the inhibition of whole blood LPS stimulated TNFα (IC50=3 nM). AMG-548 dihydrochloride inhibits Wnt signaling by directly inhibiting Casein kinase 1 isoforms δ and ε.

How to use

In Vitro:

AMG-548 dihydrochloride has a modest selectivity against JNK2 (Ki: 39 nM) and JNK3 (Ki: 61 nM). It is also extremely potent in the inhibition of whole blood LPS stimulated TNFa (IC50: 3 nM) and IL1b (IC50: 7 nM) as well as TNFa induced IL-8 (IC50: 0.7 nM) and IL-1b induced IL-6 (IC50: 1.3 nM) in human whole blood. AMG-548 dihydrochloride (10 μM) inhibits the hDvl2 shift .

In Vivo:

AMG-548 dihydrochloride has rat F of 62% and dog F of 47%. The t1/2 is 4.6 hours in rats and 7.3 hours in dogs.
