生物活性

Pimasertib (AS703026) is a highly selective, ATP non-competitive allosteric orally available MEK1/2 inhibitor[1][2].

IC50 & Target[1]

MEK1

 

MEK2

 

体外研究
(In Vitro)

Pimasertib (5, 0.5, and 0.1 μM) specifically blocks ERK1/2 activation in MM cells, cultured alone or with BMSCs. Pimasertib inhibits the growth of MM cell lines in a dose-dependent manner, with IC50s ranging from 0.005 to 2 μM. The IC50s of Pimasertib against INA-6, U266, H929 cells are 10 nM, 5 nM, 200 nM respectively. Pimasertib induces apoptosis and modulates the cell cycle profile. Pimasertib targets MM cells in the BM microenvironment[1]. Pimasertib (10 μmol/L) inhibits ERK pathway, proliferation, and transformation in cetuximab-resistant D-MUT cells[2]. Pimasertib in combination with PLX4032 significantly induces apoptosis of RPMI-7951 cells, whereas each drug used alone does not. Pimasertib synergizes with small interfering RNA-mediated downregulation of BRAF to produce results similar to those of combined treatment with PLX4032 and Pimasertib[3].

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

体内研究
(In Vivo)

Pimasertib (15, 30 mg/kg) significantly inhibits the growth of tumor in the human H929 MM xenograft model in CB17 SCID mice[1]. Pimasertib (10 mg/kg, p.o.) inhibits tumor growth of cetuximab-resistant tumor attributed by K-ras mutation[2].

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: ≥ 2.5 mg/mL (5.80 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。

    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。
  • 方案 二

    请依序添加每种溶剂: 10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: ≥ 2.5 mg/mL (5.80 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。

    1 mL 工作液为例,取 100 μL 25.0 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
[1]

The inhibitory effects of study compounds on MM cell growth and survival are assessed by both [3H]thymidine incorporation and by measuring MTT dye absorbance. Cells (104/well for MM cell line, in triplicates and 2-5×105/well for patient MM cells) are cultured in 96-well plates for 3 days (MM cell lines) or 5-days (patient MM cells). For the [3H]thymidine incorporation assay, cells are pulsed with 0.5 μCi (0.0185 MBq)/well [3H]thymidine for 6 h (cell lines), harvested onto glass fiber filters, and counted in a β-scintillation counter. Due to low DNA synthesis of patient MM cells, they are pulsed with 2 μCi/well [3H]thymidine and measured during the last 36 h of culture.

Animal Administration
[1]

CB17 severe combined immunodeficiency (SCID) mice are subcutaneously inoculated with H929 (4×106) cells in 100 μL RPMI-1640 medium. Mice developed palpable tumors (appr 130 mm3) approximately 3 weeks after cell injection and are randomized to receive orally twice daily either Pimasertib (15 or 30 mg/kg) or control vehicle alone. Tumor size is measured every other day in 2 dimensions using calipers, and tumor volume is calculated. Animals are euthanized when their tumors reach 2 cm3 in volume, when they are moribund or show paralysis or major compromise in their quality of life occurs. Tumor formation changes in mice treated with control vehicle vs. Pimasertib are plotted using the GraphPad Prism version 4.03 for Windows. Tumors are subjected to immunoblotting and immunochemistry analyses using specific monoclonal (m)Abs. Images are examined with a Leica DM LB research microscope, captured using Leica IM50 Image Manager, and processed using Adobe Photoshop Software version 7.0.

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.
