Description
PI-273 is a first reversibly and specific phosphatidylinositol 4-kinase (PI4KIIα) inhibitor with an IC50 of 0.47 μM. PI-273 can inhibit breast cancer cell proliferation, block the cell cycle and induce cell apoptosis.

How to use
In Vitro:
PI-273 (2 μM; 48 hours) blocks the cell cycle at the G2-M phase. PI-273 (2 μM; 48 hours) induces cell apoptosis in all three Ras wild-type breast cancer cells: MCF-7, T-47D, and SK-BR-3. PI-273 (0.5-2 μM; for 3 days) can suppress the AKT signaling pathway in a dose- and time-dependent manner. PI-273 of 1 μM and 2 μM inhibits the cell proliferation of both MCF-7 and T-47D cells in a time-dependent manner.
In Vivo:
PI-273 (intraperitoneal injection; 25 mg/kg/day; 15 days) profoundly suppresses the tumor volume and weight in the MCF-7 xenografts. PI-273 (0.5 mg/kg (intravenously) or 1.5 mg/kg (intragastrically); 0.08-5 hours) has a half-life of 0.411 hours for intravenous administration and 1.321 hours for intragastrical administration, and the absolute bioavailability of PI-273 is 5.1%.
