| 名稱 | NVP-TAE 226 |
| 描述 | NVP-TAE 226 (TAE226) is an effective FAK inhibitor (IC50: 5.5 nM) and most effective to Pyk2(IC50: 3.5 nM); 10- to 100-fold less effective against IGF-1R, InsR, c-Met, and ALK. |
| 細(xì)胞實(shí)驗(yàn) | Cell cultures are harvested with 0.05% trypsin and seeded in triplicate at 2 × 104 in 24-well culture plates for 24 h before drug treatment. Culture medium is used for mock treatment. Cells are harvested at the indicated day after treatment, and viable cells are counted using the Vi-cell viability analyze(Only for Reference) |
| 激酶實(shí)驗(yàn) | Kinase assay: Kinase activities are assayed in Buffer A or C at 30°C, at a final ATP concentration of 15 μM. Blank values are subtracted and activities calculated as pmoles of phosphate incorporated during a 10 min incubation. Controls are performed with appropriate dilutions of dimethylsulfoxide. In a few cases phosphorylation of the substrate is assessed by autoradiography after SDS-PAGE. GSK-3α/β is purified from porcine brain by affinity chromatography on immobilized axin. It is assayed, following a 1/100 dilution in 1 mg BSA/ml 10 mM DTT, with 5 μl 40 μM GS-1 peptide, a specific GSK-3 substrate, (YRRAAVPPSPSLSRHSSPHQSpEDEEE), in buffer A, in the presence of 15 μM [γ-32P] ATP (3,000 Ci/mmol; 1 mCi/ml) in a final volume of 30 μl. After 30 min incubation at 30°C, 25 μl aliquots of supernatant are spotted onto 2.5 × 3 cm pieces of Whatman P81 phosphocellulose paper, and 20 seconds later, the filters are washed five times (for at least 5 min each time) in a solution of 10 ml phosphoric acid/liter of water. The wet filters are counted in the presence of 1 ml ACS scintillation fluid. |
