生物活性

Isorhamnetin is a flavonoid compound extracted from the Chinese herb Hippophae rhamnoides L.. Isorhamnetin suppresses skin cancer through direct inhibition of MEK1 and PI3K.

體外研究
(In Vitro)

Isorhamnetin is a plant flavonoid that occurs in fruits and medicinal herbs. Isorhamnetin binds directly to MEK1 in an ATP-noncompetitive manner and to PI3-K in an ATP-competitive manner. In vitro and ex vivo kinase assay data show that Isorhamnetin inhibits the kinase activity of MAP/ERK kinase (MEK) 1 and PI3-K and the inhibition is due to direct binding with Isorhamnetin[1]. Isorhamnetin inhibits the Akt/mTOR and MEK/ERK signaling pathways, and promotes the activity of the mitochondrial apoptosis signaling pathway. The inhibitory effects of Isorhamnetin on breast cancer cells are determined using the CCK-8 method. Isorhamnetin inhibits the proliferation of numerous breast cancer cells (IC50, ~10 μM), including MCF7, T47D, BT474, BT-549, MDA-MB-231 and MDA-MB-468, whereas less inhibitory activity is observed in the MCF10A normal breast epithelial cell line (IC50, 38 μM)[2].

體內(nèi)研究
(In Vivo)

Photographic data shows that Isorhamnetin treatment suppresses tumor development in mice. The average volume of tumors in untreated mice increases over time and reaches a volume of 623 mm3 at 4 weeks post-inoculation; however, at this time, in mice treated with 1 or 5 mg/kg Isorhamnetin, the average tumor volume is only 280 or 198 mm3, respectively. At the end of the study, Isorhamnetin treatment (1 or 5 mg/kg) reduces tumor weight compared with the untreated control group[1].

    Solubility: 2.08 mg/mL (6.58 mM); 懸濁液; 超聲助溶

    此方案可獲得 2.08 mg/mL的均勻懸濁液，懸濁液可用于口服和腹腔注射。

    以 1 mL 工作液為例，取 100 μL 20.8 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。

Cell Assay
[2]

MCF7, T47D, BT474, BT-549, MDA-MB-231 and MDA-MB-468 breast cancer cell lines, as well as a MCF10A normal breast epithelial cell line (control) are seeded into 96-well plates at a density of 5×103 cells/well in 100 μL DMEM and placed in cell incubator for 12 h at 37°C in an atmosphere containing 5% CO2. The cells are then treated with various concentrations of Isorhamnetin (100, 33.3, 11.1, 3.7, 1.2, 0.4 and 0 μM) for 48 h, and cell proliferation rates are determined by adding 10 μL CCK-8 solution prior to incubation at 37°C for 2 h. The absorbance is measured at a wavelength of 450 nm using a SpectraMax 190 Microplate Reader. For each assay, four parallel wells are included, and the half maximal inhibitory concentration (IC50) is measured using the inhibition curve and presented as the mean of three independent experiments[2].

Animal Administration
[1]

Mice[1]
Female athymic nude mice are injected subcutaneously in the flank with A431 cells (1×106 cells in 50 μL of medium and 50 μL of Matrigel). Cells are allowed to form tumors, and once the tumors reach a size of 40 mm3, the mice are randomly assigned into groups (6 mice/group) and treated with (1 or 5 mg/kg body weight) or without Isorhamnetin in 40% DMSO/PBS buffer, administered intraperitoneally every other day for 28 days. Tumor size is measured every week with calipers, and the tumor volume is calculated. Mice are sacrificed after 28 days of treatment when the control tumors reach approximately 600 mm3. The tumors are harvested, photographed, and weighed. Tumor tissues are used for western blot analysis and immunohistochemical analysis.

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.
