Kinase assay | Initial rate constants were measured at 21 ℃ in the presence of 100 mM HEPES (pH 7.5), 0.3 mg/mL poly(Glu-Tyr) peptide substrate, 10 mM MgCl2, 1 mg/mL bovine serum albumin, 5% DMSO, 20 nM MET-KD and various concentrations of ATP and SGX523. Total reaction volumes (20 μL) were quenched with 20 μL Kinase-Glo detection buffer. Luminescence was detected in a plate-reading luminometer and the results were analyzed by nonlinear regression. |
Cell lines | MDCK cells |
Preparation method | The solubility of this compound in DMSO is >18 mg/mL. General tips for obtaining a higher concentration: Please warm the tube at 37 ℃ for 10 minutes and/or shake it in the ultrasonic bath for a while. Stock solution can be stored below - 20 ℃ for several months. |
Reacting condition | 0.04, 0.12, 0.36 and 3.0 μM; overnight |
Applications | In MDCK canine kidney epithelial cells, SGX-523 prevented HGF-induced cell scattering. |
Animal models | Nude mice bearing GTL16 gastric cancer cell xenografts |
Dosage form | 10, 20, 30, 100 mg/kg, b.i.d., or 60 mg/kg, q.d.; p.o. |
Applications | At the dose of ﹥ 10 mg /kg twice daily, SGX523 significantly retarded the growth of GTL16 xenografts. In addition, SGX523 substantially inhibited MET kinase activity. |
Other notes | Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
产品描述 | SGX-523 is a novel, potent, ATP-competitive, and highly-selective Hepatocyte growth factor receptor (MET) inhibitor with IC50 value of 4 nM [1]. SGX523 inhibits MET autophosphorylation in gastric cancer cell line GTL16 and human lung carcinoma cell line A549, with IC50 of 40 nM and 12 nM, respectively [1]. Additionally, tumor regression was observed in gastic cancer cell line GTL16 and human GBM cell line U87MG derived mouse xenograft models that are treated with SGX-523 by oral gavage [1]. SGX523 has been shown to inhibit the phosphorylateion of MEK, MAPK, AKT in brain cancer cell lines including U87, U373, DAOY, as well as glioma stem cells 1228. The inhibition of MEK in brain cancer cells and stem cells led to cell proliferation, G1/S cell cycle progression, cell migration, and cell invasion [2]. References: |
