产品描述 | NS-638 is a Ca2+-channel blocker. It can block K+-stimulated intracellular Ca2+-elevation (IC50: 3.4 μM). |
靶点活性 | Ca2+ channel:3.4 μM |
体外活性 | NS-638 dose-dependently inhibits K+-stimulated [45 Ca2+]-uptake in chick cortical synaptosomes and 2-amino-3-(3-hydroxy-5-methylisoxazol-4-yl)propionic acid (AMPA)- stimulated [3H]GABA-release from cultured cortical neurons (IC50: 2.3 and 4.3 μM), respectively. K+-stimulated intracellular Ca2+-elevation in cultured cerebellar granule cells is equipotently blocked (IC50: 3.4 μM). At this concentration, no effect on Ca2+-induced contractions in K+-depolarized guinea pig taenia coli is observed. NS-638 reversibly blocks N- and L-type Ca2+-channels in cultured chick dorsal root ganglion cells (1-30 μM). |
体内活性 | In the mouse middle cerebral artery occlusion model, NS-638 administered (50 mg/kg, i.p.) at 1 h and 6 h post-ischemia, and once a day for the next two days, results in a 48% reduction in total infarct volume. It does not show protection against ischemic neuronal damage in the gerbil model of bilateral carotid artery occlusion. |
细胞实验 | NS-638 is prepared in 1% DMSO and 1% ethanol. The effect of NS-638 on neuronal Ca2+-channels is evaluated using whole cell patch clamp techniques[1]. |

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。
