生物活性

Barlerin (8-O-Acetyl shanzhiside methyl ester) is an iridoid glucoside isolated from the leaves of Lamiophlomis rotata Kudo, a Chinese folk medicinal plant in Xi-zang. Barlerin (8-O-Acetyl shanzhiside methyl ester) could inhibt NF-κB.

IC50 & Target[1]

NF-κB

 

體外研究
(In Vitro)

Treatment of SH-SY5Y cells with Barlerin (8-O-Acetyl shanzhiside methyl ester) blocks TNF-α-induced nuclear transcription factor κB (NF-κB) activation and decreases high-mobility group box-1 (HMGB-1) expression. [1]. Treatment of H9c2 cells with Barlerin (8-O-Acetyl shanzhiside methyl ester) 9 μM blocks TNF-α-induced NF-κB phosphorylation by blocking High-mobility group box1 (HMGB1) expression[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

體內(nèi)研究
(In Vivo)

Barlerin (8-O-Acetyl shanzhiside methyl ester) 40 mg/kg demonstrates significant neuroprotective effect even after delayed administration at 4 hr after I/R. Barlerin 40 mg/kg attenuates the histopathological damage, decreases brain swelling, inhibits NF-κB activation and reduces HMGB-1 expression in ischaemic brain tissue[1]. Barlerin (8-O-Acetyl shanzhiside methyl ester) significantly promotes angiogenesis in the ischaemic brain and improves functional outcome after stroke. Barlerin also significantly increases vascularization compared with vehicle treatment. It increases the expression of VEGF, Ang1, phosphorylation of Tie2 and Akt VEGF[3]. Barlerin (8-O-Acetyl shanzhiside methyl ester) significantly shortens capillary blood clotting time and reduces blood loss volume, but does not influence mice activated partial thromboplastin time, prothrombin time or thrombin time. It significantly prolongs euglobulin clot lysis time in hyperfibrinolysis mice[4].

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: ≥ 2.5 mg/mL (5.58 mM); 澄清溶液

    此方案可獲得 ≥ 2.5 mg/mL(飽和度未知)的澄清溶液。

    1 mL 工作液為例,取 100 μL 25.0 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: ≥ 2.5 mg/mL (5.58 mM); 澄清溶液

    此方案可獲得 ≥ 2.5 mg/mL(飽和度未知)的澄清溶液。

    1 mL 工作液為例,取 100 μL 25.0 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。

Cell Assay
[2]

Prior to hypoxia, cells are pretreated with various concentrations (1, 3, 9 and 27μM) of Barlerin (8-O-Acetyl shanzhiside methyl ester) for 24 h. Cell viability are determined by MTT assay[2].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Administration
[3][4]

Rats: Barlerin (8-O-Acetyl shanzhiside methyl ester) is prepared in saline. Adult male rats are subjected to 1 hr of middle cerebral artery occlusion (MCAO) and reperfusion, and treated with or without different doses (5 and 10 mg/kg) of ND01, starting 24 hr after ischaemia and reperfusion (I/R) and by intravenous injection daily for 14 days. Neurological functional tests are performed and cerebral Evans blue extravasation is measured[3].

Mouse: Barlerin (8-O-Acetyl shanzhiside methyl ester) is prepared in saline. Male Balb/C mice (20 to 25g) are randomly divided into five groups (saline group, Hemocoagulase, 0.34 KU/kg, i.v. ASM-L, 100 mg/kg, i.v., ASM-M, 250 mg/kg, i.v., ASM-H, 500 mg/kg, i.v.). The drugs and vehicle are injected through vena caudal is 5 min before anesthetized with sodium pentobarbital (200 mg/kg, i.p.). Twenty minutes after injection, blood are drawn from heart. Activated partial thromboplastin time, prothrombin time, thrombin time and fibrinogen are assayed[4].

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.
