生物活性

Rosmarinic acid is a widespread phenolic ester compound in the plants. Rosmarinic acid inhibits MAO-A, MAO-B and COMT enzymes with IC50s of 50.1, 184.6 and 26.7 μM, respectively.

IC50 & Target

IC50: 50.1 μM (MAO-A), 184.6 μM (MAO-B), 26.7 μM (COMT)[1]

体外研究
(In Vitro)

Rosmarinic acid (RA) shows an in vitro multifunctional profile characterized by antioxidant effects, and monoamine oxidases (MAO-A and MAO-B) and catechol-O-methyl transferase (COMT) inhibition. Rosmarinic acid shows antioxidant effects against hydroxyl (HO(•)) and nitric oxide (NO) radicals (IC50 of 29.4 and 140 μM, respectively), and inhibition of lipid peroxidation (IC50 of 19.6 μM)[1]. Rosmarinic acid (RA) exerts a significant cytoprotective effect by scavenging intracellular ROS induced by UVB. In H2O2-treated cells, 2.5 μM Rosmarinic acid scavenges 60% of intracellular ROS compared to 77% of intracellular ROS scavenging effect in N-acetyl-L-cysteine (NAC)[2].

体内研究
(In Vivo)

Rosmarinic acid (RA) is a widespread phenolic ester compound in the plants, particularly those in the Labiatae family of herbs, such as Rosmarinus officinali, Salvia miltiorrhiza, and Prunella vulgaris. Rosmarinic acid suppresses colonic inflammation in dextran sulphate sodium (DSS)-induced mice via dual inhibition of NF-κB and STAT3 activation. In the DSS-induced colitis model, Treatment with Rosmarinic acid (30, 60 mg/kg, p.o.) markedly attenuates the production of cytokines[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: ≥ 2.08 mg/mL (5.77 mM); 澄清溶液

    此方案可获得 ≥ 2.08 mg/mL(饱和度未知)的澄清溶液。

    1 mL 工作液为例,取 100 μL 20.8 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% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.08 mg/mL (5.77 mM); 澄清溶液

    此方案可获得 ≥ 2.08 mg/mL(饱和度未知)的澄清溶液。

    1 mL 工作液为例,取 100 μL 20.8 mg/mL 的澄清 DMSO 储备液加到 900 μL 20% 的 SBE-β-CD 生理盐水水溶液 中,混合均匀。

    20% SBE-β-CD in Saline 的配制(4°C,储存一周):2 g SBE-β-CD(磺丁基醚 β-环糊精)粉末定容于 10 mL 的生理盐水中,完全溶解至澄清透明。

Cell Assay
[2]

Human keratinocytes (HaCaT cells) are treated with Rosmarinic acid (0.625, 1.25, 2.5, or 5 μM) and exposed to UVB radiation 1 h later. They are then incubated at 37°C for 48 h. At this time, MTT is added to each well to obtain a total reaction volume of 200 μL. After 4 h incubation, the supernatant is removed by aspiration. The formazan crystals in each well are dissolved in dimethyl sulfoxide (DMSO; 150 μL), and the absorbance at 540 nm is measured on a scanning multi-well spectrophotometer[2].

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

Animal Administration
[3]

Mice[3]
Experimental colitis is induced by giving mice drinking water ad libitum containing 5% (w/v) DSS for 7 days. Mice of each of the groups are monitored carefully every day to confirm that they have consumed an approximately equal volume of water containing DSS. For each experiment, the mice are divided into five experimental groups (n = 10/group). The first group is kept as the vehicle-treated control, and the second group is given drinking water with DSS only during the experimental period. The other three groups consist of mice receiving 5% DSS who are administrated 5-ASA (75 mg/kg/day p.o.) or Rosmarinic acid (30 or 60 mg/kg/day p.o.) daily for 7 days. Control groups are given the vehicle daily for 7 days as appropriate. Administration of each drug is initiated simultaneously with the DSS treatment.

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.
