体外研究
(In Vitro)

Riluzole 是一种抗惊厥药,属于使用依赖性 Na+ 通道阻滞剂家族,也可抑制 GABA 摄取,IC50 为 43 μM。在 20 μM 时,Riluzole 仅轻微抑制峰值自触 IPSC,但可靠地延长 IPSC。还发现 Riluzole 引起强烈的、浓度依赖性的、容易可逆的对 2 μM GABA 反应的增强。在较高浓度的 Riluzole 下,尤其是 300 μM,GABA 电流在长时间共同暴露于 2 μM GABA 和 Riluzole 时表现出明显的脱敏。Riluzole 增强 GABA 反应的 EC50 约为 60 μM[1]

体内研究
(In Vivo)

在正常幼稚大鼠中,全身注射 Riluzole (8 mg/kg,腹腔注射;n=6 只大鼠) 与在相同大鼠中测试的载体相比,减少了膝关节有害刺激诱发的超声波持续时间,但不减少可听见的发声 (P< 0.05)。全身应用 Riluzole (8 mg/kg,ip;n=19 只大鼠) 与给药前和赋形剂相比显著降低关节炎大鼠的发声 (P<0.05 至 0.001)。与给药前的值相比,将 Riluzole 给药到 CeA 中可显著缩短膝关节伤害性刺激诱发的可听和超声发声的持续时间 (n=8 只大鼠;P<0.05 至 0.01)[2]

动物实验:

请根据您的 实验动物和给药方式 选择适当的溶解方案。

以下溶解方案都请先按照 In Vitro 方式配制澄清的储备液,再依次添加助溶剂:
——为保证实验结果的可靠性,澄清的储备液可以根据储存条件,适当保存;体内实验的工作液,建议您现用现配,当天使用
以下溶剂前显示的百分比是指该溶剂在您配制终溶液中的体积占比;如在配制过程中出现沉淀、析出现象,可以通过加热和/或超声的方式助溶

  • 方案 一

    请依序添加每种溶剂: 10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.5 mg/mL (10.67 mM); 澄清溶液

    此方案可获得 ≥ 2.5 mg/mL(饱和度未知)的澄清溶液。

    1 mL 工作液为例,取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中,混合均匀;再向上述体系中加入 50 μL Tween-80,混合均匀;然后再继续加入 450 μL 生理盐水 定容至 1 mL

    生理盐水的配制:将 0.9 g 氯化钠,溶解于 ddH₂O 并定容至 100 mL,可以得到澄清透明的生理盐水溶液。
  • 方案 二

    请依序添加每种溶剂: 10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.5 mg/mL (10.67 mM); 澄清溶液

    此方案可获得 ≥ 2.5 mg/mL(饱和度未知)的澄清溶液。

    1 mL 工作液为例,取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 900 μL 20% 的 SBE-β-CD 生理盐水水溶液 中,混合均匀。

    2 g SBE-β-CD(磺丁基醚 β-环糊精)粉末定容于 10 mL 的生理盐水中,完全溶解至澄清透明。

Cell Assay
[1]

Two-electrode voltage clamp of Xenopus oocytes expressing exogenous GABAA receptors is performed with a CA-1B high performance oocyte clamp. The extracellular recording solution is ND-96 medium. Riluzole is applied from a common tip via a gravity-driven multibarrel drug-delivery system. Data acquisition and analysis are performed with pCLAMP 6 software[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Administration
[2]

Adult male Sprague-Dawley rats (180 to 350 g) are housed in a temperature-controlled room and maintained on a 12-h day/night cycle with unrestricted access to food and water. Pain behaviors are measured before and 5 h after induction of a mono-arthritis in the left knee joint. To test the effects of systemic (intraperitoneal, i.p.) application of Riluzole, pain behaviors are measured 1 h postinjection of Riluzole in normal and arthritic animals. To determine effects of Riluzole into the amygdala, pain behaviors are measured 15 min after starting Riluzole application through a stereotaxically implanted microdialysis probe. To investigate site of action in the amygdala of systemically applied Riluzole, potassium channel blockers are administered into the amygdala 45 min after systemic application of Riluzole and pain behaviors are measured 15 min later, i.e., 1 h postinjection of riluzole (i.p.)[2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
