EHT 1864 2HCl 相关产品
| 产品描述 | EHT 1864 (EHT 1864 2HCl) is a Rac family GTPase inhibitor that blocks activation by direct binding to Rac1, Rac1b, Rac2, and Rac3 (Kd=40/50/60/250 nM). EHT 1864 inhibits Rac, Ras, and Tiam-induced growth transformation of NIH-3T3 fibroblasts. |
| 靶点活性 | Rac1:40 nM(Kd), Rac2:60 nM(Kd), Rac1b:50 nM(Kd), Rac3:250 nM(Kd) |
| 体外活性 | 方法: U87-MG 细胞用 EHT 1864 (10-25 µM) 处理 5 min,通过 pull-down 检测活化 Rac1 或 RhoA 的水平。 |
| 体内活性 | 方法: 为检测体内抗肿瘤活性,将 EHT 1864 (100 mg/kg) 腹腔注射给携带 BT-474 异种移植物的 NSG 小鼠,每天两次,持续两周。 |
| 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) |
