PHA 408 (PHA-408) is a potent, selective and orally active IκB kinase-2 (IKK-2) inhibitor. PHA 408 is a powerful anti-inflammatory agent against lipopolysaccharide (LPS)- and cigarette smoke (CS)-mediated lung inflammation[1].

PHA-408 is a potentselective I kappa B-kinase 2 (IKK-2) inhibitor. PHA-408 is a tight bindingATP competitive IKK-2 inhibitor with greater than 350-fold selectivity for IKK-2 vs IKK-1 (IC50 values of 10-40 nM at IKK-2 vs 14 μM at IKK-1). PHA-408 was shown to suppress inflammatory cellular eventsand to reduce inflammation in animal models of arthritis.
