3-Phosphoinositide-dependent protein kinase 1 (PDK1) is a serine-threonine kinase that phosphorylates and activates a range of other kinases, including PKB, PKA, and certain isoforms of PKC. BX-795 is a potent, ATP-competitive inhibitor of PDK1 in vitro (IC50 = 11 nM) and in cells (IC50 = 300 nM). At comparable concentrations, BX-795 also inhibits ERK8, MAPK-interacting kinase 2, Aurora B, Aurora C, MAP/microtubule affinity-regulating kinases 1-4, TNF receptor associated factor-associated NF-κB activator-binding kinase 1, IκB kinase ε, and additional kinases.
