生物活性

ETP-46464 is an effective mTOR and ATR inhibitor with IC50s of 0.6 and 14 nM, respectively.

IC50 & Target[1]

mTOR

0.6 nM (IC50)

ATR

14 nM (IC50)

ATM

545 nM (IC50)

DNA-PK

36 nM (IC50)

PI3Kα

170 nM (IC50)

体外研究
(In Vitro)

ETP-46464 (ATRi) also inhibits DNA-PK, PI3Kα and ATM with IC50s of 36 nM, 170 nM and 545 nM, respectively[1]. Platinum-sensitive and -resistant ovarian, endometrial and cervical cancer cell lines are treated with varying levels of Cisplatin (0-50 µM) with or without the ETP-46464 (5.0 µM) and/or the KU55933 (10.0 µM) for 72 h. Single-agent dose response analyses of ETP-46464 and KU55933 in a subset of cell lines reveal a wide LD50 range of 10.0±8.7 and 38.3±7.6 µM respectively. Co-treatment doses are chosen based on these studies and previously published evidence of phospho-Chk1 (Ser345) and phospho-ATM (Ser1981) inhibition following ionizing radiation exposure and dose response treatments with ETP-46464 and KU55933. Treatment with ETP-46464 significantly increases the response of Cisplatin in all cell lines tested, resulting in 52-89% enhancement in activity and are synergistic. The combined inhibition of ATR and ATM enhances the response of Cisplatin to a level equivalent to that observed using ETP-46464 alone. These effects are independent of p53 status, and are observed in all gynecologic (GYN) cancer cells tested. Treatment with ETP-46464, but not KU55933, not only sensitizes these GYN cancer cell lines to Cisplatin, but also enhances the response of Carboplatin[2].

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

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: ≥ 0.5 mg/mL (1.06 mM); 澄清溶液

    此方案可获得 ≥ 0.5 mg/mL（饱和度未知）的澄清溶液。

    以 1 mL 工作液为例，取 100 μL 5.0 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。

Kinase Assay
[1]

Compounds (e.g., ETP-46464) and control inhibitors are delivered directly to cell media (100 μL per well) with a multi-well pipette at a final concentration of 10 μM. Media content is homogenized by carefully vortexing plates at 500 rpm. Prior to 4-hydroxy-tamoxifen (4-OHT) addition, Compounds (e.g., ETP-46464 ) are incubated at 37ºC for 15 minutes. Next, to induce ATR activity, 4-OHT is added to all wells and incubated for 60 minutes at 37ºC. Finally, cells are fixed with paraformaldehyde and processed for IF. Every compound (e.g., ETP-46464) is analyzed at least in three independent experiments[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
Cell Assay
[2]

Cells are trypsinized with 0.25% Trypsin-EDTA and counted with 0.4% Trypan Blue using an automated cell counter and plated in 96-well plates at 5000 cells per well for KLE, HEC1B and HELA and 10,000 cells per well for OVCAR3, A2780, A2780-CP20 and SIHA. After cells attach and reach approximately 60% confluency (24-48 h post seeding), media is removed and replaced with fresh media containing Cisplatin (0, 0.78, 1.56, 3.13, 6.25, 12.5, 25 or 50 µM) or Carboplatin (0, 1.56, 3.13, 6.25, 12.5, 25, 50 or 100 µM) in 0.15% DMSO, 5 µM ETP-46464, 10 µM KU55933, or a combination of 5 µM ETP-46464 and 10 µM KU55933 and incubated for 72 h. Final concentrations of ETP-46464 and KU55933 utilized are based on prior evidence indicating inhibition of ATR and ATM signaling, respectively. Single-agent dose response analyses of ETP-46464 and KU55933 in a subset of cell lines revealed a wide LD50 range (10.0±8.7 and 38.3±7.6 µM, respectively). Similarly, cells are treated with fresh media containing Cisplatin (0, 0.78, 1.56, 3.13, 6.25, 12.5, 25 or 50 µM) in 0.08% DMSO and 5 µM VE-821. Cell viability is assessed using the MTS CellTiter 96 Aqueous One Solution Cell Proliferation Assay. After a 2 h incubation at 37°C, absorbance is measured at 490 nm using a microplate spectrophotometer. Three biological replicates are performed for each cell line where each inhibitor(s)/Cisplatin concentration is assayed in triplicate for each experiment[2].

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.
