    Background
    
    BAMB-4 is an inhibitor of inositol-1,4,5-trisphosphate-3-kinase A (ITPKA) with an IC50 value of 20 µM [1].ITPKA is an InsP3 kinase. It binds to actin filaments and bundles them. This protein regulates actin dynamics as well as inositol phosphate signaling [1].BAMB-4 was almost completely taken up by H1299 cells. BAMB-4 did not belong to typical kinase inhibitors. Its relatively high specificity and high cellular uptake provide the possibility to effectively inhibit InsP3 kinase in vivo. Among InsP3Kinase inhibitors, BAMB-4 exhibit the lowest inhibition frequency. BAMB-4 showed an inhibitory effect only in 1 from 42 tested targets. There was no detected BAMB-4 target in kinase screens. These results indicated that BAMB-4 is not a typical kinase inhibitor. In vitro, data showed that BAMB-4 increased Km and reduced Vmax with respect to InsP3. BAMB-4 at the lowest concentration (10 µM) increased the Km-value for InsP3 by 160%. BAMB-4 at elevated concentrations did not further rise the Km-value for InsP3. BAMB-4 dose-dependently decreased Vmax from 75% to 50%. Decreased Vmax and increased Km in presence of inhibitor indicated that BAMB-4 might belong to mixed type inhibitors. Data showed that BAMB-4 also reduced Vmax and increased Km with respect to ATP [2].There is still no any available result of the application of BAMB-4 in animals.
