产品描述 | EHT 1864 is a effective Rac family GTPase inhibitor for Rac1/Rac1b/Rac2/Rac3 (Kd: 40/50/60/250 nM). |
靶点活性 | Rac2:60 nM(Kd), Rac1b:50 nM(Kd), Rac3:250 nM(Kd), Rac1:40 nM(Kd) |
体外活性 | EHT 1864 selectively inhibits Rac-induced lamellipodia formation, and specifically reverses cell transformation induced by constitutively activated mutants of Rac1 and Tiam1. EHT 1864 strongly impaires oncogenic Ras-induced cell proliferation in NIH 3T3 cells stably expressing H-Ras(61L) protein. [1] EHT 1864 also reduces both extracellular and intracellular levels of Aβ peptides by inhibiting the γ-secretase-dependent cleavage of APP. [2] In cultured hippocampal pyramidal neurons, EHT 1864, via inhibition of Rac1, rescues the phenotype induced by Rich2 knock-down. [3] |
体内活性 | EHT 1864 (40 mg/kg i.p.) significantly reduces Abeta 40 and Abeta 42 levels in guinea pig brains. [2] |
激酶实验 | Inhibitor:GTPase binding analyses: For inhibitor:GTPase binding analyses, aliquots of small GTPase solution (containing 1 μM inhibitor) are titrated into a solution of 1 μM inhibitor in the cuvette. Changes in fluorescence anisotropy are monitored at λex = 360 nm, λem = 440 nm, 30 s after each addition. All data analysis and curve fitting were performed using Microsoft Excel and QuantumSoft's ProFit for Mac OS X. |
细胞实验 | NIH 3T3 cells stably expressing oncogenic Ras are plated in 96-well plates. The cells are cultured for up to 4 days in complete growth medium, either alone, or supplemented with 5 μM EHT 1864. Cell growth is then assessed using the conversion of MTT to a formazan product. Briefly, the MTT reagent (from a 5 mg/ml solution diluted in PBS) is added to the wells at a final concentration of 0.5 mg/ml, and the cells are further incubated for 4 h at 37°C. The medium is then removed, and the reaction is terminated by adding 100 μl/well Me2SO. The absorbance is read at 570 nm using a microplate reader.(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。
