CAY10505 is a phosphoinositide 3-kinase gamma (PI3Kγ) specific inhibitor and improves hypertension-associated vascular endothelial dysfunction.
cay10505 is a potent and selective pi3kγ inhibitor (ic50= 30 nm)pi3k (phosphatidylinositol-4,5-bisphosphate 3-kinase) is a family of enzymes involved in cellular functions such as cell growth, proliferation, differentiation, motility, survival and intracellular trafficking, which in turn are involved in cancer. it plays a key role in pi3k/akt/mtor pathway.in neurons treated with 3.5 μm ba, 200 nm cay10505 partially reduced the baicalein-induced akt phosphorylation. [1]in hypertensive rats, cay10505 at 0.6 mg.kg-1 p.o. exhibited the following effects 1) effectively reduced mabp; 2) significantly ameliorated vascular endothelium dysfunction in hypertensive rats in combination of doca; 3) prominently increased serum nitrite and/or nitrate concentrations.4) prevented hypertension-induced attenuation of ach-induced endothelium-dependent relaxation.[2]
