生物活性

製品説明 BIO (GSK-3 Inhibitor IX, 6-bromoindirubin-3-oxime, 6-Bromoindirubin-3'-oxime, MLS 2052) is a specific inhibitor of GSK-3 with IC50 of 5 nM for GSK-3α/β in a cell-free assay, shows >16-fold selectivity over CDK5, also a pan-JAK inhibitor with IC50 of 30 nM for Tyk2. BIO induces apoptosis in human melanoma cells.
in vitro BIO (6-bromoindirubin-3'-oxime) is a specific inhibitor of glycogen synthase kinase-3 (GSK-3), with IC50 of 5 nM for GSK-3α/β, shows >16-fold selectivity over CDK5. BIO interacts within the ATP binding pocket of these kinases, reduces β-catenin phosphorylation on a GSK-3-specific site in cellular models, closely mimicks Wnt signaling in Xenopus embryos. [1] In human and mouse embryonic stem cells, BIO maintains the undifferentiated phenotype and sustains expression of the pluripotent state-specific transcription factors Oct-3/4, Rex-1 and Nanog. BIO-mediated Wnt activation is functionally reversible, as withdrawal of the compound leads to normal multidifferentiation programs in both human and mouse embryonic stem cells. [2] BIO promotes proliferation in mammalian cardiomyocytes. [3]6BIO is also a pan-JAK inhibitor, with IC50 values of 0.03, 1.5, 8.0, 0.5 μM for TYK2, JAK1, JAK2 and JAK3. BIO selectively inhibits phosphorylation of STAT3 and induces apoptosis of human melanoma cells. [4]
in vivo BIO suppresses melanoma tumor growth in a mouse xenograft model. [4]
特徴 The first pharmacological agent shown to maintain self-renewal in human and mouse embryonic stem cells.

キナーゼアッセイ 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.
細胞アッセイ 細胞株 COS1, Hepa or SH-SY5Y cells
濃度 ~10 μM
反応時間 12 or 24 h
実験の流れ COS1, Hepa (wild-type, CEM/LM AhR deficient and ELB1 ARNT deficient), or SH-SY5Y cells are grown in 6 cm culture dishes in Dulbecco's Modified Medium (DMEM) containing 10% fetal bovine serum. For treatment, IO (5 μM), BIO (5 or 10 μM), MeBIO (5 or 50 μM), LiCl (20 or 40 mM), or mock solution (DMSO, 0.5% final concentration) is added to medium when cell density reaches ∼70% confluence. After 12 (SH-SY5Y) or 24 hours, the cells, while still in plate, are lysed with lysis buffer (1% SDS, 1 mM sodium orthovanadate, 10 mM Tris [pH 7.4]). The lysate is passed several times through a 26G needle, centrifuged at 10,000 × g for 5 min, and adjusted to equal protein concentration. About 8 μg of each sample is loaded for immunoblotting. Enhanced chemiluminescence is used for detection. The following primary antibodies are used: mouse anti-β-catenin CT (Upstate Biotechnolgies, Clone 7D8, recognizes total β-catenin), mouse anti-phospho-β-catenin (Upstate Biotechnologies, Clone 8E7, recognizes dephosphorylated β-catenin), mouse anti-GSK-3 β, mouse anti-GSK-3 phosphoTyr216, rabbit anti-AhR (Aryl hydrocarbon receptor), and rabbit anti-actin.
