生物活性

Poloxin is a non-ATP competitive Polo-like Kinase 1 (PLK1) inhibitor that targets the polo-box domain, with an IC50 of appr 4.8 μM.

IC50 & Target[4]

PLK1 PBD

4.8 μM (IC50)

PLK2 PBD

18.7 μM (IC50)

PLK3 PBD

53.9 μM (IC50)

体外研究
(In Vitro)

Poloxin (25 μM) induces defects in centrosome integrity, spindle formation, and chromosome alignment in mitosis. Centrosomal fragmentation induced by Poloxin is partially rescued by Kiz T379E. Poloxin (25 μM) activates the mitotic checkpoint, induces apoptosis and inhibits proliferation of MDA-MB-231 cells[1]. Poloxin inhibits proliferation in both cell lines with a comparable efficiency through 72 h period[2]. Poloxin inhibits the polo-box domain (PBD) interaction with an apparent IC50 of ∼4.8 μM. Poloxin exhibits a loose Plk1 PBD specificity with 4-10 times higher IC50 values for Plk2 and Plk3, and does not significantly inhibit other types of phosphopeptide-binding domains such as FHA, WW, and SH2 domains[3].

体内研究
(In Vivo)

Poloxin (40 mg/kg) decreases the proliferation of MDA-MB-231 cells, and surpresses the growth of the tumor nude mice bearing established xenografts of MDA-MB-231[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: ≥ 1.43 mg/mL (4.81 mM); 澄清溶液

    此方案可获得 ≥ 1.43 mg/mL(饱和度未知)的澄清溶液。

    1 mL 工作液为例,取 100 μL 14.3 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% Corn Oil

    Solubility: ≥ 1.43 mg/mL (4.81 mM); 澄清溶液

    此方案可获得 ≥ 1.43 mg/mL(饱和度未知)的澄清溶液,此方案实验周期在半个月以上的动物实验酌情使用。

    1 mL 工作液为例,取 100 μL 14.3 mg/mL 的澄清 DMSO 储备液加到 900 μL玉米油中,混合均匀。

Cell Assay
[2]

Cell Viability Assay on treated cells in 96-well plates, based on viable cells. 20 μL of CellTiter-Blue®reagent is added to each well and then incubated at 37°C with 5% CO2 for 4h before fluorescence reading using a Victor 1420 Multilabel Counter. All experiments are performed in triplicate and at least three independent experiments are performed. Data are presented as percentage compared with control.

Animal Administration
[1]

Viable MDA-MB-231 or HeLa cells (1×106) are resuspended in 300 μL of 0.9% NaCl and s.c. injected into both flanks of nude mice (MDA-MB-231: n=8 mice in each group, total N=16; HeLa: n=7 mice in each group, total N=14). Approximately 3 weeks after inoculation, mice are treated with Poloxin (40 mg/kg) or TQ (20 mg/kg) by intratumoral injection on Mondays, Wednesdays, and Fridays for 5 to 6 weeks. The tumor area is calculated by multiplication of the greatest diameter with the perpendicular diameter every 2 to 3 days. Measurements of all tumors within the group are represented by the mean value. U-tests and Student's t-tests are performed for statistical evaluation among MDA-MB-231 groups and between HeLa groups, respectively. All mice are properly treated in accordance with the guidelines of the local animal committee.

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.
