体外研究
(In Vitro)

Imperatorin 是一种植物次生代谢产物,属于香豆素类,特别是呋喃香豆素类。Imperatorin 通过 α1β2γ2S 受体增强 GABA 诱导的氯离子电流(IGABA)。Imperatorin 对 IGABA 的增强作用在 100 μmol 时分别为 50.5 %和 300 μmol 时为 109.8 %。Imperatorin 和 Phellopterin,发现于白芷的根部,在体外抑制 [3H] 地西泮与大鼠脑 GABAA 受体的苯二氮?类位点结合,Imperatorin 的 IC50 为 12.3 μmol,而 Phellopterin 为 400 nmol。Imperatorin 在 3.5 ~ 14 mmol 浓度范围内,通过不可逆地与 GABA-T 活性位点结合,以时间和浓度依赖性方式显著地不可逆地抑制 GABA-T。Imperatorin 是一种可逆性乙酰胆碱酯酶(AChE)抑制剂,其作用呈剂量依赖性。采用分光光度法检测 Imperatorin 和当归果实粗提物在12.5、25、50、100 μg/mL 浓度下的 AChEBChE 抑制活性。Imperatorin 对 AChE 的抑制率为 13.75 ~ 46.11%,而对BChE的抑制率为37.46 ~ 83.98%。Imperatorin 对 BChE 而非 AChE 具有选择性,其对 BChE 的 IC50为 31.4 μmol。Imperatorin 和 (+)-Byakangelicol 被发现是最有效的 BACE-1 抑制剂,其 IC50s 分别为 91.8 和104.9 μmol。Imperatorin(IC50=9.2 μmol)也能有效抑制 NO 合成[1]
Imperatorin 是 TRPV1 的弱激动剂, TRPV1 参与检测多种伤害性刺激,表现为EC50为12.6±3.2 μM[2]

体内研究
(In Vivo)

Imperatorin (10, 20 mg/kg)注射后30分钟表现出抗焦虑作用,并改善了记忆和学习过程的不同阶段,包括获得和巩固[1]
Imperatorin(10, 20 mg/kg) 可以降低尼古丁(0.1 mg/kg,s.c)的焦虑效应[1]
Imperatorin(30, 40 mg/kg, i.p. )著增强卡马西平对电休克诱导的最大惊厥的抗惊厥活性,分别将ED50从10.8 mg/kg降至6.8 mg/kg(34%)和6 mg/kg(42%)[1]
Imperatorin(10, 20 mg/kg) 和卡马西平6.8 mg/kg 使卡马西平的脑总浓度从1.260 μg/mL增加到2.328 μg/mL(增加了85%),这可能是通过改变血屏障通透性或像多药耐药蛋白的抑制剂引起的[1]
Imperatorin 可使γ -氨基丁酸转氨酶失活并抑制乙酰胆碱酯酶活性[1]
Imperatorin(5和10 mg/kg)急性给药可改善东莨菪碱损害的记忆获取和巩固, 在注射东莨菪碱(1 mg/kg)之前[1]
Imperatorin (10 mg/kg, 7天,每天2次)显著减弱东莨菪碱对记忆获取的影响,而当测定记忆巩固时,5和10 mg/kg的 Imperatorin 有效[3]

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 (9.25 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% Corn Oil

    Solubility: ≥ 2.5 mg/mL (9.25 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,此方案实验周期在半个月以上的动物实验酌情使用。

    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玉米油中,混合均匀。

Animal Administration
[3]

Mice[3]
The experiments are carried out on naive male Swiss mice weighing 20-25 g. Drugs are administered intraperitoneally (i.p.) at the volume of 10 mL/kg. Fresh drug solutions are prepared on each day of experimentation. Control groups receive saline injections of the same volume and via the same route of administration. During the acute treatment, the animals are allocated to the following drug groups: saline, rivastigmine (0.5 mg/kg, i.p.), scopolamine (1 mg/kg, i.p.), Imperatorin (1, 5, 10 mg/kg, i.p.), or Imperatorin coadministered with scopolamine. To measure the memory acquisition processes, scopolamine is administered 20 min before the pretest, whereas Imperatorin and rivastigmine are administered 30 min before the pretest. To measure the memory consolidation processes, rivastigmine or scopolamine (1 mg/kg) is administered immediately after the pretest, whereas Imperatorin is administered 15 min after pretest or after scopolamine injection. On the second day, the mice are retested. In the second set of the experiments, animals are randomly allocated to receive 6 days of i.p. injections of Imperatorin (1, 5, and 10 mg/kg, i.p.) or saline, twice daily (8:00 a.m. and 8:00 p.m.). On the seventh day, these animals are subjected to saline, scopolamine (1 mg/kg, i.p.), Imperatorin (1, 5, and 10 mg/kg, i.p.), or Imperatorin coadministered with scopolamine. To measure the memory acquisition processes, scopolamine is administered 20 min before the pretest and Imperatorin 30 min before the pretest. To measure the memory consolidation processes, scopolamine (1 mg/kg) is administered immediately after the pretest, whereas Imperatorin is administered 15 min after the pretest or after scopolamine injection. On the eighth day, the mice are retested.

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.
