Description

General description

A cell-permeable morpholino-thienopyrimidine compound that acts as a potent and isoform-selective inhibitor of PI 3-kinases (IC₅₀ = 2 nM, 16 nM, 660 nM, and 220 nM for p110α, p110β p110γ, and PI 3-K C2β, respectively) and inhibits non-PI 3-K kinases only at much higher concentrations (IC₅₀ ≥3.4 µM for Cdk2/E, KDR, PKA, and PKCα). Shown to inhibit cell proliferation (IC₅₀ = 580 nM) and serum-stimulated Akt phosphorylation (IC₅₀<3 µM) in A375 melanoma cells.
