PDK-1 (3-Phosphoinositide-dependent protein kinase 1), a member of the protein A, G and C (AGC) family of proteins, is a Ser/Thr protein kinase. PDK-1, is the pivotal node in the PI3K pathway, has a key role in insulin and growth-factor signalling through phosphorylation and subsequent activation of a number of other AGC kinase family members, such as protein kinase B.

PDK-1 is responsible for the regulation of cell proliferation and migration and it also has been found to play a key role in different cancers, pancreatic and breast cancer amongst others. Many cancer-driving mutations induce activation of PDK-1 targets including Akt, S6K (p70 ribosomal S6 kinase) and SGK. Thus, PDK1 is a critical activator of multiple pro-survival and oncogenic protein kinases, for which it has garnered considerable interest as an oncology drug target.

    PF-5177624
    		Inhibitor
    PF-5177624 is a specific and potent inhibitor of PDK1, a key enzyme in the PI3K/AKT signaling pathway that is frequently dysregulated in breast cancer. PDK1 phosphorylates AKT at T308 and other substrates, activating downstream signaling pathways that are important for tumor progression. PF-5177624 blocks IGF-1-stimulated PDK1 activity and downstream AKT and p70S6K phosphorylation, reducing cell proliferation and transformation in breast cancer cells.

    mIDH1-IN-2
    		Inhibitor
    mIDH1-IN-2 is a brain-penetrant isocitrate dehydrogenase 1 (IDH1) inhibitor. mIDH1-IN-2 shows subnanomolar potency against IDH1 R132H and R132C (IC50 = 80.0 and 58.0 nM) and minimal activity against wt-IDH1/2. mIDH1-IN-2 also inhibits PDK1 (IC50 = 0.61 μM) and reduces PDH phosphorylation dose-dependently. mIDH1-IN-2 can inhibit cells proliferation, induces S phase arrest and promotes apoptosis. mIDH1-IN-2 can be used for the research of cancer, such as glioma.

    BX795 (Standard)
    		Inhibitor
    BX795 (Standard) is the analytical standard of BX795 (HY-10514). This product is intended for research and analytical applications. BX795 is a potent and selective inhibitor of PDK1, with an IC50 of 6 nM. BX795 is also a potent and relatively specific inhibitor of TBK1 and IKKε, with an IC50 of 6 and 41 nM, respectively. BX795 blocks phosphorylation of S6K1, Akt, PKCδ, and GSK3β, and has lower selectivity over PKA, PKC, c-Kit, GSK3β etc. BX795 modulates autophagy.
