生物活性
靶点	PDK1 PDK-1, IC50:10 nM
描述	PDK1 (3-phosphoinositide-dependent protein kinase 1) plays an important role in growth factor signalling cascades by phosphorylating and activating a group of protein kinases belonging to the AGC [PKA (protein kinase A)/PKG (proteinkinase G)/PKC (protein kinase C)]-kinase family. GSK2334470 inhibits PDK1 with an IC_₅₀ of ~10 nM. Addition of GSK2334470 to HEK (human embryonic kidney)-293, U87 or MEF (mouse embryonic fibroblast) cells ablated T-loop residue phosphorylation and activation of SGK isoforms and S6K1 induced by serum or IGF1 (insulin-like growth factor 1). GSK2334470 also inhibited T-loop phosphorylation and activation of Akt, but was more efficient at inhibiting Akt in response to stimuli such as serum that activated the PI3K (phosphoinositide 3-kinase) pathway weakly. GSK2334470 inhibited activation of an Akt1 mutant lacking the PH domain (pleckstrin homology domain) more potently than full-length Akt1, suggesting that GSK2334470 is more effective at inhibiting PDK1 substrates that are activated in the cytosol rather than at the plasma membrane. GSK2334470 also suppressed T-loop phosphorylation and activation of RSK2 (p90 ribosomal S6 kinase 2), another PDK1 target activated by the ERK (extracellular-signal-regulated kinase) pathway^[2]. Furthermore, chemical inhibition of PDK1 using the specific inhibitor GSK2334470 (1 µM) resulted in total abrogation of the EGF-induced intracellular calcium increase and inositol phosphates accumulation in MDA-MB-231 cells^[3].
