LY294002, a well-known PI3K signaling pathway inhibitor, is the first synthetic PI3Kα, δ and β inhibitor with IC50 of 500nM, 570nM and 970nM, respectively. LY294002 is not exclusively selective for the PI3Ks, and could in fact act on other lipid kinases and additional apparently unrelated proteins[1]

When LY294002 was added to NPC cells with different concentrations, levels of phosphorylation (S473) Akt were decreased in treated NPC cells, exhibiting a dose-response effect. LY294002 markedly inhibited NPC CNE-2Z cell growth, proliferation, and induced apoptosis in vitro and in vivo[2]. The PI3k/AKT pathway is constitutively activated in a majority of human pancreatic cancer cell lines and the pathway is a promising target for therapeutic intervention. LY294002 produce apoptosis and antiproliferative effects on pancreatic carcinoma cells in vivo and in vitro[3]

LY294002(1.2 mg/kg) was given together with leptin (60 µg/kg) once daily for 14 days via the intraperitoneal (i.p.) route. The result found that body weight in leptin+LY294002-treated rats decreased significantly and STEH was higher (p < 0.001). Ratio of testicular phosphor-Akt/total Akt was significantly higher in leptin+LY294002-treated rats (p < 0.001). The adverse effects of leptin were prevented by concurrent administration of LY294002, suggest the potential involvement of the PI3K signaling pathway in leptin-induced detrimental effects on spermatozoa[4]
