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^[1]. LY294002 also inhibits CK2 with an IC₅₀ of 98 nM^[2]. LY294002 is a competitive DNA-PK inhibitor that binds reversibly to the kinase domain of DNA-PK with an IC₅₀ of 1.4 μM. LY294002 is an apoptosis activator^[3].

LY294002 (0-75 μM; 24 hours and 48 hours) remarkably decreases human nasopharyngeal carcinoma CNE-2Z cells in a dose-dependent fashion^[4].
LY294002 (0-75 μM; 24 hours and 48 hours ) induces CNE-2Z cells apoptosis rate in dose-dependent^[4].
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^[4].
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^[6].

LY294002 (10, 25, 50, 75 mg/kg; i.p.; twice weekly; for 4 weeks) significantly reduces mean NPC tumor burden in a dose-dependent manner. LY294002 (10, 25 mg/kg) is less effective in decreasing tumor burden^[4].
LY294002 (1.2 mg/kg per day; i.p.; for 14 days) prevents Leptin (60 ug/kg)-induced adverse effects on spermatozoa in Sprague-Dawley rats^[5].
