Synonym | GNE317; GNE 317; GNE-317 |
Chemical Name | 5-(6-(3-methoxyoxetan-3-yl)-7-methyl-4-morpholinothieno[3,2-d]pyrimidin-2-yl)pyrimidin-2-amine |
In Vitro | Kinase Assay: GNE-317 is a PI3K/mTOR inhibitor, is able to cross the blood-brain barrier (BBB). Cell Assay: GNE-317 is not a substrate of P-gp or BCRP transporter in transfected Madin-Darby canine kidney (MDCK) cells. Binding of GNE-317 to plasma proteins exhibits a free fraction of 14.9 % in mouse plasma, and binding to brain tissues is higher, with a free fraction of 5.4%. GNE-317 shows cytostasis but no cell death to U87 cells. |

In Vivo | GNE-317 (40 mg/kg, p.o.) markedly inhibits the PI3K pathway in mouse brain, causing 40% to 90% suppression of the pAkt and pS6 signals up to 6-hour postdose. GNE-317 (40 mg/kg, p.o.) is efficacious in the U87 and GS2 orthotopic models, achieving tumor growth inhibition of 90% and 50%, respectively. In the GBM10 tumor model, GNE-317 (30 mg/kg, p.o.; 40 mg/kg the first 2 weeks) extends the survival of mice from a median of 55.5 to 75 days. |
Animal model | U87 and GS2 orthotopic tumor-bearing mice. |
Formulation & Dosage | Dissolved in 0.5% methylcellulose/0.2%Tween 80; 40 mg/kg; Oral administration |
