PI3Kα

6.8 nM (IC50)

PI3Kδ

240.3 nM (IC50)

PI3Kγ

体外研究
(In Vitro)

CNX-1351 能够有效地 (EC50<100 nM) 特异性抑制 PI3Kα 依赖性癌细胞系中的信号传导，从而产生有效的抗增殖作用 (GI50<100 nM)。CNX-1351 抑制 SKOV3 细胞中的 PI3K 信号传导，效力 (EC50 为 10-100 nM) 与泛 PI3K 抑制剂相似。为了研究抑制细胞中 PI3Kα 的功能性后果，使用 CNX- 1351 并监测生长。暴露于 CNX-1351 96 小时 (GI50 分别为 78 和 55 nM)，两种 PIK3CA 驱动的细胞系的生长均受到抑制[1]。

体内研究
(In Vivo)

CNX-1351 抑制小鼠脾脏中的 p-AktSer473 并在体内与 PI3Kα 结合。CNX-1351 以 100 mg/kg 的剂量每天一次连续 5 天递送到裸鼠的腹腔内 (每组 n=3 只小鼠)。在最后一次给药后的指定时间 (1-24 小时) 从小鼠身上采集脾脏，并通过免疫印迹检测 P-AktSer473 或 PI3Kα 占用情况。PI3K 信号传导的抑制被检测为 P-AktSer473 在最后一次给药后 1 小时和 4 小时的减少[1]。

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: ≥ 2.5 mg/mL (4.36 mM); 澄清溶液

Kinase Assay
[1]

CNX-1351 is tested in a panel of 10 lipid kinases. CNX-1351s tested in a 10-concentration IC50 curve with 3-fold serial dilution starting at 1 μM. Reactions are carried out at 10 μM ATP. An HTRF assay format is used for PI3Kα, PI3Kβ, PI3Kγ, and PI3Kδ; ADP-GLO assay format is used for other kinases. The following substrates are used: for HTRF, phosphatidylinositol 4,5-bisphosphate; for SPHK1 and SPHK2, sphingosine; for other ADP-GLO enzymes, phosphatidylinositol. For general kinase selectivity, CNX-1351 is run in a kinase selectivity panel at using HotSpot technology and radioisotope-based P81 filtration. CNX-1351 is dissolved in pure DMSO to the final 1 μM test concentration. Substrates for the various kinases tested against CNX-1351 are prepared fresh daily in reaction buffer. Any required cofactors are then added to the substrate solution followed by kinase addition and preincubated for 30 min at room temperature. 33P-ATP (10 μM) is delivered into the reaction mixture to initiate the reaction, and reaction continued for 2 h at room temperature. The reaction is terminated, and any unreacted phosphate is washed away using 0.1% phosphoric acid prior to detection utilizing a proprietary technology. The study is performed in duplicate, and 10 μM staurosporine, a nonselective, ATP-competitive kinase inhibitor, is used as the positive control[1].

Cell Assay
[1]

SKOV3 cells or MCF-7 cells are plated in SKOV3 proliferation assay medium (DMEM supplemented with 5-10% FBS and pen/strep) at a density of 5000 cells in 180 μL volume per well in Costar no. 3610 white 96-well clear flat-bottom plates and incubated overnight in a humidified 37°C incubator. A standard curve ranging from 10 000 to 50 000 cells is set up in a separate plate and allowed to adhere to the plate for 4-6 h, at which time the plate is developed using Cell Titer-Glo. The next morning, 3-fold compound dilutions ranging from 10 000 to 40 nM are prepared in proliferation medium containing 1% DMSO. Then 20 μL of each dilution is added to the SKOV3 or MCF-7 cells plated the previous day, resulting in a dose-response curve from 1000 to 4 nM. The cells are incubated for 96 h and then developed with Cell Titer Glo. The cell numbers at the end of the assay are determined using the standard curve generated at the start of the assay. Growth inhibition is calculated using the following formulas, and GI50 values are determined[1].

Animal Administration
[1]

Mice[1]
Female nu/nu (n=3/group) are administered compound (GDC-0941 or CNX-1351) delivered ip at 100 mg/kg once daily for 5 consecutive days. After delivery of the last dose, spleens from treated animals are harvested at 1, 4, and 24 h time points. Spleens are immediately frozen in liquid nitrogen. Samples are stored at -80°C until processing for homogenates. Homogenates are made by adding approximately 100 μL of spleen sample to a Precellys homogenizing tube containing 300 μL of cell extraction buffer plus Complete protease inhibitor and PhosStop phosphatase inhibitor and kept on ice. The sample is homogenized in a Precellys 24 homogenizer for 15 s followed by centrifugation at 16000g for 20 min at 4°C. The supernatant is moved to a new tube, and the protein concentration is determined by BCA Assay.

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.
