Product Introduction
Bioactivity
英文名: OSI-930
描述: OSI-930 是 Kit,KDR 和 CSF-1R (c-Fms)的口服选择性抑制剂,IC50分别为 80 nM,9 nM 和 15 nM。它具有抗肿瘤活性,靶向肿瘤中的癌细胞增殖和血管生成。它还适度抑制 Flt-1,c-Raf 和 Lck,并且对 PDGFRα/β,Flt-3和 Abl 具有较弱的抑制活性。
细胞实验: For assays of cell proliferation and apoptosis, cells are seeded into 96-well plates and incubated for 2 to 3 days in the presence of OSI-930 at various concentrations. Inhibition of cell growth is determined by luminescent quantitation of the intracellular ATP content using CellTiterGlo. Induction of caspase-dependent apoptosis by OSI-930 is quantitated by an enzymatic caspase 3/7 assay. Inhibition of angiogenesis by OSI-930 is monitored using the rat aortic ring endothelial sprout outgrowth assay. Sections of aorta are prepared from CO2-euthanized male rats and cultured in vitro in a collagen matrix in the presence or absence of OSI-930. The collagen matrix is prepared from type 1 rat tail collagen solubilized in 0.1% acetic acid at 3 mg/mL, which is combined with 0.125 volume collagen buffer (0.05 N NaOH, 200 mM HEPES, 260 mM NaHCO3), 0.125 volume of medium 199, 0.0125 volume of 1 M NaOH, and 1% GlutaMax. Aortic rings are embedded in 0.4 mL of this matrix in six-well plates, to which 0.5 mL endothelial basal medium and the appropriate amount of OSI-930 is added; the rings are then incubated for 10 days and the resultant angiogenic sprout outgrowth is digitally quantitated from images by measurement of the sprout-containing area within a series of concentric rings around the aortic tissue area.(Only for Reference)
激酶实验: Protein kinase assays : Protein kinase assays are either done in-house by ELISA-based assay methods (Kit, KDR, PDGFRα, and PDGFRβ) or by a radiometric method. In-house ELISA assays used poly(Glu:Tyr) as the substrate bound to the surface of 96-well assay plates; phosphorylation is then detected using an antiphosphotyrosine antibody conjugated to HRP. The bound antibody is then quantitated using ABTS as the peroxidase substrate by measuring the absorbance at 405/490 nm. All assays uses purified recombinant kinase catalytic domains that are either expressed in insect cells or in bacteria. The Kit and EGFR protein used for in-house assays are prepared internally; other enzymes are obtained. Recombinant Kit protein is expressed as an NH2-terminal glutathione S-transferase fusion protein in insect cells and is initially purified as a nonphosphorylated (nonactivated) enzyme with a relatively high Km for ATP (400 μM). In some assays, an activated (tyrosine phosphorylated) form of the enzyme is prepared by incubation with 1 mM ATP for 1 hour at 30 °C. The phosphorylated protein is then passed through a desalting column to remove the majority of the ATP and stored at ?80 °C in buffer containing 50% glycerol. The resultant preparation has a considerably higher specific activity and a lower Km for ATP (25 μM) than the initial nonphosphorylated preparation. The inhibition of Kit autophosphorylation by OSI-930 is assayed by incubation of the nonphosphorylated enzyme at 30 °C in the presence of 200 μM ATP and various concentrations of OSI-930. The reaction is stopped by removal of aliquots into SDS-PAGE sample buffer followed by heating to 100 °C for 5 minutes. The degree of phosphorylation of Kit is then determined by immunoblotting for both total Kit and phosphorylated Kit.
体外活性: 在HMC-1, NCI-SNU-5, COLO-205和U251移植瘤模型中,口服OSI-930(200 mg/kg)能够够抑制肿瘤细胞增殖.
