Notes: PI-103 is a potent, cell-permeable, ATP-competitive inhibitor of PI3K family members with selectivity toward DNA-PK, PI3K (p110α), and mTORC1. The IC50 values are 2, 8, 20, 26, 48, 83, 88, and 150 nM for DNA-PK, p110α, mTORC1, PI3-KC2β, p110δ, mTORC2, p110β, and p110γ, respectively.{14312} PI-103 exhibits antiproliferative activity against a panel of glioma cell lines in vitro at a concentration of 0.5 µM. It also inhibits growth of established human glioma tumor xenografts in vivo with no observable toxicity.{14311}
