AMG-548

Research use only, not for human use.

AMG-548 is a potent and selective inhibitor of p38α with Ki of 0.5 nM, dispalys weak inhibition for p38β (Ki=3.6 nM), and >5,000-fold selectivity over p38γ and p38δ.

AMG-548 is a potent and selective inhibitor of p38α with Ki of 0.5 nM, dispalys weak inhibition for p38β (Ki=3.6 nM), and >5,000-fold selectivity over p38γ and p38δ; shows >1,000-fold selectivity over other 36 kinases, and is efficacious in acute and chronic models of arthritis. Rheumatoid Arthritis Discontinued.

AMG-548 shows >1000 fold selective against p38γ (Ki=2600 nM) and p38δ (ki=4100 nM). AMG-548 has an modest selectivity against JNK2 (ki=39 nM) and JNK3 (ki=61 nM). AMG-548 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 (IC5050=1.3 nM) in human whole blood. AMG-548 (10 μM) inhibits the hDvl2 shift.

AMG-548 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.
