产品描述 | KN-93 phosphate is a novel membrane-permeant synthetic inhibitor of purified neuronal CaMK-II with K i of 370 nM. KN-93 phosphate inhibits serum-induced fibroblast cell growth in a comparable dose-dependent fashion to its inhibition of CaMK-II activity. |
靶点活性 | CaMK II:0.37 μM(Ki) |
体外活性 | After 2 days of KN-93 treatment, 95% of cells are arrested in G1. G1 arrest is reversible; 1 day after KN-93 release, a peak of cells had progressed into S and G2-M. KN-93 also blocks cell growth stimulated by basic fibroblast growth factor, platelet-derived growth factor-BB, and epidermal growth factor in NIH 3T3 fibroblasts [1]. KN-93 inhibits the H +, K + -ATPase activity but strongly dissipates the proton gradient formed in the gastric membrane vesicles and reduces the volume of luminal space [2]. KN-93 (0.5 μM) prevents increased LV developed pressure during action potential prolongation and early afterdepolarizations. Ca 2+ -independent CaM kinase activity is increased during early afterdepolarizations. The increase in CaM kinase activity is prevented by pretreatment with KN-93 [3]. |
激酶实验 | Measurement of activities of autophosphorylated/non-autophosphorylate CaMKII: CaMKII activity is measured utilizing syntideII as a substrate. Purified CaMKII is pre-incubated in the assay mixture ( 35 mM Hepes-Na ( pH 8.0 ), 10 mM MgC12, 0.5 μM CaM, 5 μM ATP, 1 mM CaCl2 or 1 mM EGTA, total 25 μL) at 30 °C for 2 minutes. After this pre-incubation, the protein substrate/radioactive ATP mixture is added to the same test tube and the preparation is further incubated at 30 °C, for 5 minutes ( final assay condition; 35 mM Hepes-Na (pH 8.0), 10 mM MgCl2, 0.125 μM CaCl2, 20 μM syntideII, 11.25 μM [ γ-32P] ATP, 10 % DMSO and indicated concentrations of KN-93, supplemented with 0.25 mM CaCl2 and 2 mM EGTA (for autophosphorylated samples) or 0.25 mM EGTA and 2 mM CaCl2 (for nonautophosphorylated samples ), total 100 μL ). The reaction is terminated by adding of 25 μL of 100 % ( w/v ) ice-cold TCA. After centrifugation, 80 μL of the supernatant is applied to phosphocellulose paper. The filters are then washed with 75 mM H3P04 for 15 min with continuous agitation. After 4-cycles of washing, the radioactivity retains on the filter paper is quantified in a liquid scintillation counter. |
细胞实验 | NIH 3T3 fibroblasts are cultured on polystyrene dishes in DMEM and fetal bovine serum, supplemented with penicillin/streptomycmn in a 5% CO2 humidified chamber at 37 癈. Cell growth is measured by using the MTT dye reduction method. (Only for Reference) |

请在以下方框中输入您的动物实验信息后点击计算,可以得到母液配置方法和体内配方的制备方法: 比如您的给药剂量是10 mg/kg,每只动物体重20 g,给药体积100 μL,一共给药动物10 只,您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。
母液配置方法:2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL), 如您需要配置的浓度超过该产品的溶解度,请先与我们联系。
体内配方的制备方法:取 50 μL DMSO 主液,加入 300 μL PEG300, 混匀澄清,再加 50 μL Tween 80,混匀澄清,再加 600 μL ddH2O, 混匀澄清。
