PI3Kα-IN-33
PI3Kα-IN-33 is an orally active and selective PI3Kα inhibitor with an IC50 of 9.9 nM. PI3Kα-IN-33 blocks the PI3K/Akt/mTOR signaling pathway. PI3Kα-IN-33 induces apoptosis and triggers G2/M-phase arrest via Cyclin B1 and CDK1 downregulation. PI3Kα-IN-33 can be used for the research of colorectal cancer.

PI3Kα-IN-33 (Compound 8b) forms a stable, high-affinity complex with PI3Kα[1].
PI3Kα-IN-33 (48 h) potently inhibits proliferation of multiple cancer cell lines, with the highest activity against HCT-116 colorectal cancer cells (IC50 = 0.53 μM), and has reduced cytotoxicity toward normal HEK293 cells (IC50 = 7.42 μM)[1].
PI3Kα-IN-33 (2.0 μM; 12 h) effectively inhibits the migratory ability of HCT-116 colorectal cancer cells[1].
PI3Kα-IN-33 (0.5-2.0 μM; 2 weeks) inhibits colony formation of HCT-116 colorectal cancer cells in a concentration-dependent manner[1].
PI3Kα-IN-33 (0.5-2.0 μM; 48 h) induces selective G2/M-phase arrest in HCT-116 colorectal cancer cells at concentrations of 0.5, 1.0, and 2.0 μM[1].
PI3Kα-IN-33 (0.5-2.0 μM; 48 h) at concentrations of 0.5, 1.0, and 2.0 μM causes concentration-dependent downregulation of Cyclin B1 and CDK1 in HCT-116 colorectal cancer cells[1].
PI3Kα-IN-33(0.5-2.0 μM; 48 h) at concentrations of 0.5, 1.0, and 2.0 μM triggers concentration-dependent activation of the mitochondrial apoptotic pathway and induction of DNA double-strand breaks in HCT-116 colorectal cancer cells[1].
PI3Kα-IN-33 (0.5-2.0 μM; 24 h) triggers concentration-dependent mitochondrial membrane potential depolarization in HCT-116 colorectal cancer cells[1].
PI3Kα-IN-33 (0.5-2.0 μM; 48 h) induces concentration-dependent apoptosis in HCT-116 colorectal cancer cells, with 33.3% total apoptosis at 2.0 μM[1].
PI3Kα-IN-33 (1.0-5.0 μM; 48 h) concentration-dependently inhibits the PI3K/Akt/mTOR signaling pathway in HCT-116 colorectal cancer cells[1].
PI3Kα-IN-33 blocks the PI3K-Akt-mTOR axis in HCT-116 colorectal cancer cells, driving transcriptional reprogramming of oncogenic and metabolic pathways including suppressed glycolysis and MTORC1 signaling[1].
