(In Vitro)

Riluzole 是一種抗驚厥藥,屬于使用依賴性 Na+ 通道阻滯劑家族,也可抑制 GABA 攝取,IC50 為 43 μM。在 20 μM 時(shí),Riluzole 僅輕微抑制峰值自觸 IPSC,但可靠地延長(zhǎng) IPSC。還發(fā)現(xiàn) Riluzole 引起強(qiáng)烈的、濃度依賴性的、容易可逆的對(duì) 2 μM GABA 反應(yīng)的增強(qiáng)。在較高濃度的 Riluzole 下,尤其是 300 μM,GABA 電流在長(zhǎng)時(shí)間共同暴露于 2 μM GABA 和 Riluzole 時(shí)表現(xiàn)出明顯的脫敏。Riluzole 增強(qiáng) GABA 反應(yīng)的 EC50 約為 60 μM[1]。

體內(nèi)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) 與在相同大鼠中測(cè)試的載體相比,減少了膝關(guān)節(jié)有害刺激誘發(fā)的超聲波持續(xù)時(shí)間,但不減少可聽見的發(fā)聲 (P< 0.05)。全身應(yīng)用 Riluzole (8 mg/kg,ip;n=19 只大鼠) 與給藥前和賦形劑相比顯著降低關(guān)節(jié)炎大鼠的發(fā)聲 (P<0.05 至 0.001)。與給藥前的值相比,將 Riluzole 給藥到 CeA 中可顯著縮短膝關(guān)節(jié)傷害性刺激誘發(fā)的可聽和超聲發(fā)聲的持續(xù)時(shí)間 (n=8 只大鼠;P<0.05 至 0.01)[2]。

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.
