生物活性

GDC-0623 (RG 7421) is a potent, ATP-uncompetitive inhibitor of MEK1 (Ki=0.13 nM, +ATP), and displays 6-fold weaker potency against HCT116 (KRAS (G13D), EC50=42 nM) versus A375 (BRAFV600E, EC50=7 nM).

IC50 & Target[1]

MEK1

0.13 nM (Ki, +ATP)

体外研究
(In Vitro)

GDC-0623 (RG 7421) and G-573 are able to prevent MEK phosphorylation by CRAF in vitro, and able to block MEK phosphorylation by BRAF(V600E)[1]. GDC-0623 (RG 7421) is potent, ATP-uncompetitive inhibitors of MEK1 but shows distinct shifts in cellular activity compared with the other two inhibitors, only 6-fold half-maximum effective concentration (EC50) decreases[2].

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

体内研究
(In Vivo)

GDC-0623 (RG 7421) (40 mg/kg, p.o.) shows percent tumour growth inhibition (%TGI) in MiaPaCa-2 xenograft model. GDC-0623 (RG 7421) and G-573 show superior antitumour activity compared to GDC-0623 (RG 7421) in all three KRAS models[1].

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 (5.48 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 (5.48 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]

Flag-MEK1 mutants, S212P and S212A, are generated using the QuickChange site directed mutagenesis kit. Mammalian expression vectors for N-terminal Flag tagged MEK-1 are expressed in HCT116 cells. 1.8×106 HCT116 cells are plated in 10 cm plate and transfected on the following day with 17 μg of expression constructs using lipofectamine 2000. After 48 hours cells are treated with inhibitors for the indicated times, harvested and lysed in 100 μL cell extraction buffer. Cell lysates from each sample are analyzed by SDS-PAGE. Membranes are incubated with phospho-MEK S221, phospho-ERK1/2 and MEK1 primary antibodies and immunoreactive proteins are analyzed by SuperSignal West Pico Chemiluminescent Substrate.

Animal Administration
[1]

Colo205 xenografts are established by inoculating 5×106 cells resuspended in Hank's Balanced Salt Solution (HBSS) subcutaneously (s.c.) in the rear right flank of 6-8 week old female nude (nu/nu) mice. NCI-H2122 xenografts are established by inoculating 1×107 cells resuspended in Hank's Balanced Salt Solution (HBSS) plus matrigel (growth factor reduced) s.c. in the rear right flank of 6-8 week old female nu/nu mice. Both A375 and MiaPaca-2 xenografts are initiated by transplanting 1 mm3 tumor fragments from their respective passaged tumors s.c. into the flank of athymic nu/nu mice. When tumors reached appr 200 mm3, mice are randomized and treated with daily (QD) oral gavage (PO) with either vehicle [methylcellulose 0.1% tween 80 0.1% (MCT)], GDC-0973 (at 10 mg/kg), GDC-0623 (RG 7421) (40 mg/kg), or G-573 (100 mg/kg). All doses of MEK inhibitors represented maximal tolerated doses (MTDs), resulting in no more than 15-20% body weight loss. Tumor volumes are determined using digital calipers using the formula (L×W×W)/2. Tumor growth inhibition (%TGI) iscalculated as the percentage of the area under the fitted curve (AUC) for the respective dose group per day in relation to the vehicle. Animal weights are recorded twice per week and mice are removed from study if body weights dropped ≥20%. Partial responses (PRs) are defined as any tumor demonstrating a ≥ 50% decrease in tumor volume, whereas complete responses (CRs) are defined as any tumor demonstrating 100% reduction in tumor volume at any point during the study.

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.
