Biological Activity for PIK 90

PIK 90 is a potent inhibitor of PI 3-K α/γ/δ kinases (IC50 = 11, 18, 47, 58 and 64 nM against p110α, p110γ, PI 3-KC2α, p110δ and PI 3-KC2α, respectively) as well as PIKKs (IC50 = 13 nM against DNA-PK). It inhibits the fMLP-stimulated phosphorylation of Akt and impairs polarity and chemotaxis in dHL60 cells. It suppresses insulin-stimulated phosphorylation of Akt and rpS6 in 3T3-L1 adipocytes and L6 myotubes in vitro and prevents insulin-induced blood glucose reduction in mice in vivo. PIK 90 can be used in combination with other small molecules and proteins for mesendoderm induction in protocols to differentiate iPSCs into organ-specific mesenchyme.
