體內(nèi)研究
(In Vivo)

(-)-Epicatechin gallate (Epicatechin gallate), a component of Rhei Rhizoma, is one of the active components of Onpi-to, a herbal medicine composed of five crude drugs (Rhei Rhizome, Glycyrrhizae Radix, Ginseng Radix, Zingiberis Rhizoma and Aconiti Tuber). Following intravenous injection of (-)-Epicatechin gallate (1.0 mg/kg) in rats, the plasma concentration vs. time curve is fitted in a three compartment model. Pharmacokinetic parameters for plasma Epicatechin gallate (ECG) are measured. ECG has a t1/2α of 0.038 h, a t1/2βof 0.291 h and a t1/2γ of 4.033 h . The CLtot of ECG is 4.19 L/h ? kg. The Vdss is 12.39 L/kg[2].

以下溶解方案都請先按照 In Vitro 方式配制澄清的儲備液，再依次添加助溶劑：
——為保證實驗結(jié)果的可靠性，澄清的儲備液可以根據(jù)儲存條件，適當(dāng)保存；體內(nèi)實驗的工作液，建議您現(xiàn)用現(xiàn)配，當(dāng)天使用；
以下溶劑前顯示的百分比是指該溶劑在您配制終溶液中的體積占比；如在配制過程中出現(xiàn)沉淀、析出現(xiàn)象，可以通過加熱和/或超聲的方式助溶

  • 方案 一

    請依序添加每種溶劑： 10% DMSO    40% PEG300    5% Tween-80    45% Saline

    Solubility: ≥ 2.17 mg/mL (4.91 mM); 澄清溶液

    此方案可獲得 ≥ 2.17 mg/mL（飽和度未知）的澄清溶液。

    以 1 mL 工作液為例，取 100 μL 21.7 mg/mL 的澄清 DMSO 儲備液加到 400 μL PEG300 中，混合均勻；再向上述體系中加入 50 μL Tween-80，混合均勻；然后再繼續(xù)加入 450 μL 生理鹽水 定容至 1 mL。

    生理鹽水的配制：將 0.9 g 氯化鈉，溶解于 ddH?O 并定容至 100 mL，可以得到澄清透明的生理鹽水溶液。
  • 方案 二

    請依序添加每種溶劑： 10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.17 mg/mL (4.91 mM); 澄清溶液

    此方案可獲得 ≥ 2.17 mg/mL（飽和度未知）的澄清溶液。

    以 1 mL 工作液為例，取 100 μL 21.7 mg/mL 的澄清 DMSO 儲備液加到 900 μL 20% 的 SBE-β-CD 生理鹽水水溶液 中，混合均勻。

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

Animal Administration

Rats[2]
Male Sprague-Dawley rats, obtained at 7 weeks of age (210-245 g) are used. Epicatechin gallate (ECG) is suspended in 0.5% w/v sodium carboxymethylcellulose at 12.5, 25.0 and 50.0 mg/10 mL for oral administration to rats at 10 mL/kg. For intravenous injection in rats at 1.0 mg/kg, an ethanolic solution of Epicatechin gallate is diluted with 10% w/v sodium citrate solution to 1.0 mg/mL; the final concentration of ethanol is 1% v/v[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.
