摘要: The PI3K/Akt signaling pathway is a key in cell proliferation, growth, survival, protein synthesis, and glucose metabolism. It has been recognized recently that inhibiting this might provide viable therapy for cancer. A series of bis(morpholino-1,3,5-triazine) derivatives were prepared optimized to the highly efficacious PI3K/mTOR inhibitor 1-(4-{[4-(dimethylamino)piperidin-1-yl]carbonyl}phenyl)-3-[4-(4,6-dimorpholin-4-yl-1,3,5-triazin-2-yl)phenyl]urea 26 (PKI-587). Compound shown excellent activity vitro vivo, with antitumor efficacy both subcutaneous orthotopic xenograft tumor models when administered intravenously. structure−activity relationships vivo analogues are described.
