Schizandrin B

Schisandrin B is a dibenzocyclooctadiene derivative isolated from Fructus Schisandrae, has been shown to produce antioxidant effect on rodent liver and heart. SB inhibited mitogen-induced proliferation and cytokine secretion by lymphocytes. SB also significantly inhibited mitogen-induced upregulation of T cell costimulatory molecules and activation markers. Similar anti-inflammatory effects of SB on lymphocyte proliferation and cytokine secretion were also observed in vivo³. Sch B can protect neuronal cells against oxidative challenge, presumably by functioning as a hormetic agent to sustain cellular redox homeostasis and mitoenergetic capacity in neuronal cells⁴. Sch B may exert neuroprotective activity by attenuating the microglial-mediated neuroinflammatory response by inhibiting the TLR4-dependent MyD88/IKK/NF-κB signaling pathway⁵. Sch B significantly suppressed the spontaneous lung and bone metastasis of 4T1 cells inoculated s.c. without significant effect on primary tumor growth and significantly extended the survival time of these mice⁶.

溶解方案(细胞实验)

DMSO 中的溶解度 : 100 mg/mL (249.71 mM; 超声助溶; 吸湿的 DMSO 对产品的溶解度有显著影响，请使用新开封的 DMSO)

溶解方案(动物实验)

"方案 一": "请依序添加每种溶剂：10% DMSO 40% PEG300 5% Tween-80 45% SalineSolubility: ≥ 2.5 mg/mL (6.24 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。以 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。"
