product name AP-III-a4 (ENOblock)
Description: AP-III-a4 (also known as ENOblock) is a novel small molecule which is the first, nonsubstrate analogue that directly binds to enolase and inhibits its activity (IC50=0.576 uM); inhibit cancer cell metastasis in vivo. In HCT116 cells, AP-III-a4 induces cell death under hypoxia, and inhibits cancer cell migration and invasion by down-regulation of AKT and Bcl-xL expression. In Huh7 hepatocytes and HEK kidney cells, AP-III-a4 induces glucose uptake and inhibits phosphoenolpyruvate carboxykinase (PEPCK) expression.

In vitro activity: In HCT116 cells, AP-III-a4 induces cell death under hypoxia, and inhibits cancer cell migration and invasion by down-regulation of AKT and Bcl-xL expression. In Huh7 hepatocytes and HEK kidney cells, AP-III-a4 induces glucose uptake and inhibits phosphoenolpyruvate carboxykinase (PEPCK) expression. Kinase Assay: A single unit of enolase is defined as the amount of enzyme that produces 1 μmol of phosphoenol pyruvate from phospho-D-glycerate/min in standard assay. Enolase activity assay is measured at 37°C by incubating pure enolase (3–9 U) in a buffer containing 50 mM imidazole-HCl (pH 6.8), 2.0 mM MgSO4 and 400 mM KCl in the absence or presence of ENOblock or NaF. The reaction is initiated by adding 1 μmol of 2-phospho-D-glycerate, and the OD is measured after 10 min of reaction time with a spectrophometer at 240 nm. Cell Assay: 3 x 105 HCT116 cells are seeded in a 6 well plate. 24 h later, cells are treated with compound of interest (with or without prior induction of hypoxia for 4 h) for 24 h using triplicate wells. Cells are then trypsinized and resuspended in 2.5 mL PBS. A 100 μL aliquot is taken for staining with 0.2% trypan blue solution and counted using a hemocytometer. 150 cells are counted and dead cells are classified as those that could not exclude trypan blue. |

| In Vivo | In a HCT116-xenotransplanted zebrafish tumor xenograft model, AP-III-a4 (10 μM) inhibits cancer cell migration and invasion processes. In vivo, AP-III-a4 (10 μM) also causes downregulation of PEPCK expression and induction of glucose uptake, and inhibits adipogenesis and foam cell formation. |
