PI3Kα-IN-14 (compound F8), a potent PI3Kα inhibitor, exhibits an IC50 value of 0.14 nM and markedly diminishes mitochondrial membrane potential, resulting in cell cycle arrest at the G1 phase and apoptosis in U87-MG cells. Additionally, it demonstrates significant antiproliferative effects against various tumor cell lines, including PC-3 with an IC50 of 0.28 μM, HCT-116 with an IC50 of 0.57 μM, and U87-MG with an IC50 of 1.37 μM [1].
