Schisandrin (Schizandrin), a dibenzocyclooctadiene lignan, is isolated from the fruit of Schisandra chinensis Baill. Schisandrin exhibits antioxidant, hepatoprotective, anti-cancer and anti-inflammatory activities. Schisandrin also can reverses memory impairment in rats^[1][2][3].

Schisandrin (10-100 μM; pretreated for 2 h) inhibits LPS-stimulated NO production, iNOS protein and mRNA expression in a dose-dependent manner in RAW 264.7 cells^[1].
Schisandrin (25-100 μM; pretreated for 2 h) inhibits prostaglandin E2 production, COX-2 protein and mRNA expression in LPS-stimulated RAW 264.7 macrophages^[1].
Schisandrin inhibits the SK-HEP-1, SNU-638, and T47D cells proliferation, with IC₅₀s of 42.0, 53.1, and 40.0 μM, respectively^[3].
Schisandrin (10-60 μM; 48 h) enhances Doxorubicin -induced apoptosis and selectively reverses MCF-7/DOX resistance^[4].

Schisandrin (10-100 mg/kg; a single i.p.) inhibits acetic acid-induced peritoneal vascular permeability and reduces the carrageenan-induced paw edema of mice^[1].
Schisandrin (1-10 mg/kg; a single p.o.) significantly reverses the Scopolamine-induced impairment of spatial memory and passive avoidance response, and enhances tremors induced by Oxotremorine in rats^[2].

请根据产品在不同溶剂中的溶解度选择合适的溶剂配制储备液；一旦配成溶液，请分装保存，避免反复冻融造成的产品失效。
储备液的保存方式和期限：-80°C, 6 months; -20°C, 1 month。-80°C 储存时，请在 6 个月内使用，-20°C 储存时，请在 1 个月内使用。

In Vivo:

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

• 1.

  请依序添加每种溶剂： 10% DMSO    40% PEG300    5% Tween-80    45% saline

  Solubility: ≥ 0.28 mg/mL (0.65 mM); Clear solution

  此方案可获得 ≥ 0.28 mg/mL (0.65 mM，饱和度未知) 的澄清溶液。

  以 1 mL 工作液为例，取 100 μL 2.8 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中，混合均匀；向上述体系中加入50 μL Tween-80，混合均匀；然后继续加入 450 μL生理盐水定容至 1 mL。

  将 0.9 g 氯化钠，完全溶解于 100 mL ddH₂O 中，得到澄清透明的生理盐水溶液
