Potent 3-phosphoinositide-dependent protein kinase (PDPK1) inhibitor (IC50 ~ 10 nM). Exhibits no effect on other kinases including Aurora, ROCK, p38 MAPK and PI 3-K. Suppresses T-loop phosphorylation and subsequent activation of PDK1 substrates S6K1, SGK and RSK in vitro; exhibits limited inhibitory effect on Akt activation. Delays melanomagenesis and metastasis in BrafV600E::Pten(-/-) mice. Purity 98%. MW (observed): 462.59
