生物活性

Tetrahydropalmatine (DL-Tetrahydropalmatine) hydrochloride possesses analgesic effects. Tetrahydropalmatine hydrochloride acts through inhibition of amygdaloid release of dopamine to inhibit an epileptic attack in rats[1].

IC50 & Target

Dopamine[1]

体内研究
(In Vivo)

Tetrahydropalmatine (THP), an active component isolated from corydalis (a Chinese herbal medicine), possesses analgesic effects. Picrotoxin treatment alone has a significant effect on the following activity measure: there is an increase in horizontal motion time (HMT), vertical motion time (VMT), clockwise turnings (CT), anticlockwise turning (ACT) and a decrease in freezing time (FT). Tetrahydropalmatine treatment alone causes a decrease in HMT, VMT and total distance traveled (TDT), but an increase in FT. Pretreatment of rats with an i.p. dose of 10 mg/kg or 15 mg/kg of Tetrahydropalmatine significantly attenuates the Picrotoxin-induced enhancement in HMT, VMT, CT, ACT and TDT, as well as reduction in FT. Another 48 rats under urethane anesthesia are randomly divided into six groups, each of eight rats. The s.c. injection of Picrotoxin causes an increase in amygdaloid release of dopamine (DA), while i.p. injection of Tetrahydropalmatine at 10 mg/kg has an insignificant effect on amygdaloid release of DA. Again, the Picrotoxin-induced increase in amygdaloid release of DA is significantly attenuated by pretreatment with Tetrahydropalmatine. The Picrotoxin-induced augmented amygdaloid release of DA is almost completely abolished by pretreatment with Tetrahydropalmatine 30 min before s.c. injection of Picrotoxin[1].

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 (6.38 mM); 澄清溶液; 超声助溶

    此方案可获得 2.5 mg/mL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 (6.38 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。

    20% SBE-β-CD in Saline 的配制(4°C,储存一周):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。

Animal Administration
[1]

Rats[1]
Male Sprague-Dawley rats, weighing 250-320 g, are used in the present study. The animals are housed in a temperature-regulated (22±1°C) room on 12:12 h light/dark cycles with food and water available ad libitum. The light is turned on at 06:00 h and turned off at 18:00 h. At least two major groups of animals are studied. (1) Vehicle-treated rats: received an i.p. injection of 0.9% saline plus Picrotoxin (3-4 mg/kg, s.c.). (2) Tetrahydropalmatine-treated rats: receive an injection of Tetrahydropalmatine (10 mg/kg, i.p.) plus Picrotoxin (3-4 mg/kg, s.c.). The effects of s.c. administration of Picrotoxin or Tetrahydropalmatine on locomotor activity are assessed in unanesthetized rats. On the other hand, the effects of Picrotoxin or Tetrahydropalmatine on amygdaloid DA release are assessed in rats under urethane (1.4 g/kg, i.p.) anesthesia[1].
Seventy-two unanesthetized rats are randomly divided into nine groups, each of eight rats. The animals are adapted to the behavior apparatus for 30 min before an injection of Picrotoxin (3 or 4 mg/kg, s.c.), Tetrahydropalmatine (10 or 15 mg/kg, i.p.) or saline. Then, the locomotor activities of these rats are recorded during the 30-min period following the injections[1].

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.
