Target	PI3Kα:22.0 nM (IC50) PI3Kδ:39.8 nM (IC50) PI3Kβ:129.0 nM (IC50) PI3Kγ:717.3 nM (IC50) mTOR:152.0 nM (IC50) DNA-PK:70.6 nM (IC50)
In Vitro	ETP-45658 (10 μM; 4 h) decreases in the phosphorylation of FOXO3a, Gsk3-β and p70 S6K in U2OS cells[1]. ETP-45658 inhibits the proliferation of MCF7, PC3, 786-O, HTC116, and U251 cells, with EC50s of 0.48 μM, 0.49 μM, 2.62 μM, 3.53 μM, and 5.56 μM, respectively[1]. ETP-45658 (10 μM; 24 h) induces a clear G1 arrest of PC3 cells[1]. ETP-45658 inhibits the mutant PI3Kα proteins, H1047R and E545K, with IC50s of 16.8 nM and 13.1 nM, respectively[1]. ETP-45658 (5 nM-11.1 μM; 1 h) induces a dose-dependent increase of GFP-FOXO nuclear translocation in U2foxRELOC cells[1]. ETP-45658 (10 μM; 1 h) decrease the expression of cyclin D1 and p-Akt on serine 473 in U2OS cells[1]. Western Blot Analysis[1] Cell Line: U2OS cells Concentration: 10 μM Incubation Time: 4 hours Result: Caused a 95% decrease in the phosphorylation of FOXO3a at threonine 32 and a 55% reduction on Gsk3-β at serine 9. Reduced the phosphorylation of the mTOR substrate p70 S6K.
In Vivo	ETP-45658 (22.7 mg/kg) decreases the level of phosphorylated Akt on serine 473 in the mammary ducts of transgenic mice[1].
