specific and selective p110α inhibitor with IC50 of 32,30 and p110α/H1047R, respectively. A66 S potently blocks phosphorylation lines tested demonstrates that some cell types are highly than 100 fold less active against the other class-I PI 3-kinase 200 protein kinases when tested at 10 micromolar. This p110alpha inhibitor available for research purposes. A66 S is
