产品描述 | A 438079 hydrochloride (A-438079 HCl) is a potent and selective P2X7 receptor antagonist with pIC50 of 6.9. |
靶点活性 | P2X7:6.9(pIC50) |
体外活性 | A-438079可部分明显抑制6-OHDA诱导的纹状体DA存量的消耗.用A-438079预处理降低HC模型中疼痛行为指数.触发癫痫发作60分钟后腹腔注射A-438079(5和15 mg/kg)可减少海马内癫痫发作的严重程度和神经元死亡.神经病大鼠模型静脉注射80 μMol/kg A-438079,可减少不同类别脊髓神经元有害和无害的诱发活性. |
体内活性 | A-438079在浓度达100 μM时对P2X7受体也有选择性。A-438079在稳定表达大鼠P2X7受体的1321N1细胞中,可阻断10 μM BzATP-引起的细胞内钙离子浓度变化,IC50为321 nM。 |
激酶实验 | Human astrocytoma cells, 1321N1, are grown to stably express rat P2X7, human P2X4, P2X2a, P2X2/3, P2X1, P2Y1?and P2Y2 recombinant receptors. Agonist, BzATP, 2,3-O-(4-ben-zoylbenzoyl)-ATP or ATP-induced changes in intracellular Ca2+?concentrations are assessed in all of the cell lines using the Ca2+?chelating dye, Fluo-4, in conjunction with a Fluorometric Imaging Plate Reader. The cells are plated out the day before the experiment onto poly-D-lysine-coated black 96 well plates. After the agonist addition, changes in intracellular Ca2+ concentrations are recorded, per second, for 3 min. Ligands are tested at 11 half-log concentrations from 10-10 to 10-4 M. BzATP or ATP concentrations corresponds to the EC70?values for each receptor to enable comparison of antagonist potencies across the multiple P2 receptor subtypes. A 438079 is added to the cell plate and ?uorescence data are collected for 3 min before the addition of agonist, subsequently, data are then collected for another 2 min. The pEC50 or pIC50 values are derived from a single curve ?t. |

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。
