生物活性

Dp44mT is an iron chelator with selective anticancer activity.

IC50 & Target

Target: Iron chelator[1]

体外研究
(In Vitro)

Dp44mT is cytotoxic to breast cancer cells, at least in part, due to selective inhibition of top2α. Dp44mT alone induced selective cell killing in the breast cancer cell line MDA-MB-231 when compared with healthy mammary epithelial cells (MCF-12A). It induces G1 cell cycle arrest and reduces cancer cell clonogenic growth at nanomolar concentrations. Dp44mT, but not the iron chelator desferal, induces DNA double-strand breaks quantified as S139 phosphorylated histone foci (γ-H2AX) and Comet tails induced in MDA-MB-231 cells. Doxorubicin-induced cytotoxicity and DNA damage are both enhanced significantly in the presence of low concentrations of Dp44mT. The chelator caused selective poisoning of DNA topoisomerase IIα (top2α) as measured by an in vitro DNA cleavage assay and cellular topoisomerase-DNA complex formation[1]. Dp44mT targets lysosome integrity through copper binding. Copper binding is essential for the potent antitumor activity of Dp44mT, as coincubation with nontoxic copper chelators markedly attenuated its cytotoxicity[2].

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 (8.76 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 (8.76 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。

Kinase Assay
[1]

For DNA topoisomerase IIα assays, the 161-bp fragment from pBluescript SK(-) phagemid DNA or single stranded oligonucleotides are 5'-end labeled with [32P]ATP and T4 polynucleotide kinase. Labeling mixtures are subsequently centrifuged through Mini Quick Spin DNA columns (for pSK fragments) or Oligo columns (for oligonucleotides) to remove the unincorporated label. Annealing to the complementary strand of the oligonucleotides is done by heating the reaction mixture to 95°C and overnight cooling to room temperature in 10 mM Tris-HCl (pH 7.8), 100 mM NaCl, and 1 mM EDTA. DNA substrates (10 pmol/reaction) are incubated with 500 ng of top2a or top2h in the presence or absence of Dp44mT for the indicated times at 25°C in 10 μL of reaction buffer. Reactions are stopped by adding SDS (final concentration 0.5%). Samples are separated on 16% (for pSK DNA) or 20% (for the oligonucleotides) denaturing polyacrylamide gels (7 M urea). Imaging and quantitation are done using a PhosphorImager[1].

Cell Assay
[1]

Cell proliferation is measured using a sulforhodamine B dye–based assay. MDA-MB-231(breast cancer) and MCF-12A (healthy mammary epithelial) cells are incubated with increasing concentrations of Dp44mT (0.01, 0.1, 1, 10, 100 μM). Results are expressed relative to control[1].

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.
