生物活性

LY294002 is a broad-spectrum inhibitor of PI3K with IC50s of 0.5, 0.57, and 0.97 μM for PI3Kα, PI3Kδ and PI3Kβ, respectively. LY294002 also inhibits CK2 with an IC50 of 98 nM. LY294002 is a competitive DNA-PK inhibitorr that binds reversibly to the kinase domain of DNA-PK with an IC50 of 1.4 μM. LY294002 is an apoptosis activator.

体外研究

LY294002 (0-75 μM; 24 hours and 48 hours) remarkably decreases human nasopharyngeal carcinoma CNE-2Z cells in a dose-dependent fashion.
LY294002 (0-75 μM; 24 hours and 48 hours ) induces CNE-2Z cells apoptosis rate in dose-dependent.
LY294002 (10-75 μM) significantly decreases p-Akt (S473) expression levels and up-regulates caspase-9 activity in CNE-2Z cells. Total Akt protein level is not difference with different concentration.
LY294002 (5, 10, 100 µM; for 2 hours) treatment partially suppresses Lysophosphatidic acid (LPA)-induced (20 µM; for 4 hours) nuclear translocation of YAP, accompanied by a reduction in p-AKT levels.
