产品描述 Linopirdine (DuP 996) is a TRPV1 agonist. Linopirdine is an orally active and selective M-type K+ current (IM; Kv7; KCNQ Channels) inhibitor (IC50: 2.4 μM). Linopirdine is a cognitive enhancer. It acts by stimulating release of acetylcholine and other neurotransmitters.Linopirdine is a putative cognition-enhancing drug that increases acetylcholine release in rat brain tissue.
靶点活性 K+ current, M-type:2.4 μM
体外活性 Linopirdine is a well known blocker of voltage-gated potassium channels from the Kv7 (or KCNQ) family that generate the so called M current in mammalian neurons. Kv7 subunits are also expressed in pain-sensing neurons in dorsal root ganglia, in which they modulate neuronal excitability. Linopirdine acts as an agonist of TRPV1 (transient receptor potential vanilloid type 1), another ion channel expressed in nociceptors and involved in pain signaling. Linopirdine induces increases in intracellular calcium concentration in human embryonic kidney 293 (HEK293) cells expressing TRPV1, but not TRPA1 and TRPM8 or in wild-type HEK293 cells. Linopirdine also activates an inward current in TRPV1-expressing HEK293 cells that is almost completely blocked by the selective TRPV1 antagonist capsazepine. At low concentrations linopirdine sensitizes both recombinant and native TRPV1 channels to heat, in a manner that is not prevented by the Kv7-channel opener flupirtine. Linopirdine exerts an excitatory action on mammalian nociceptors not only through inhibition of the M current but also through activation of the capsaicin receptor TRPV1[4].
体内活性 Linopirdine (i.v.; 0.1-6 mg/kg; increasing doses) transiently (10-15 min) and dose-dependently enhances MAP by up to 15%[2].

TargetMol Calculator 体内实验配液计算器

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。
