PI-273 (2 μM; 48 hours) blocks the cell cycle at the G2-M phase[1].
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[1].
PI-273 (0.5-2 μM; for 3 days) can suppress the AKT signaling pathway in a dose- and time-dependent manner[1].
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[1].
