生物活性

A-385358 is a selective inhibitor of Bcl-XL with Kis of 0.80 and 67 nM for Bcl-XL and Bcl-2, respectively.

0.8 nM (Ki)

Bcl-2

67 nM (Ki)

体外研究
(In Vitro)

A-385358 is a selective inhibitor of Bcl-XL with Kis of 0.80 and 67 nM for Bcl-XL and Bcl-2, respectively, in fluorescence polarization assays. Treatment of IL-3-deprived FL5.12/Bcl-XL cells for 24 hours with A-385358 results in cell killing with an EC50 of 0.47±0.05 μM (n=68). This effect is accompanied by an increase in caspase-3 activity. Consistent with the greater affinity for the Bcl-XL versus Bcl-2 hydrophobic grooves, the EC50 of A-385358 for IL-3-depleted FL5.12/Bcl-2 cells (1.9±0.1 μM; n=55) is 4-fold higher relative to the cytokine-deprived FL5.12/Bcl-XL cells. In addition, A-385358 is more effective at stimulating cytochrome c release from mitochondria isolated from FL5.12/Bcl-XL versus Bcl-2 cells[1].

体内研究
(In Vivo)

The combination of A-385358 given at 100 mg/kg/d plus the lower dose of paclitaxel produces a significant reduction in tumor growth (%T/C) compare with paclitaxel monotherapy. This combination also yields a >100% increase in time for tumors to reach 900 mm3 (%ILS) compare with vehicle control. Maximal efficacy is observed during the dosing period for A-385358, with slow but steady increase in the tumor growth after termination of treatment. The combination of A-385358 at 75 mg/kg/d plus paclitaxel at 30 mg/kg/d is also well tolerated and inhibits tumor growth rate by nearly 80%. Significant effects on tumor growth relative to paclitaxel monotherapy are observed with doses as low as 50 mg/kg/d[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 (3.91 mM); 悬浊液; 超声助溶

    此方案可获得 2.5 mg/mL的均匀悬浊液，悬浊液可用于口服和腹腔注射。

    以 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 (3.91 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。

    以 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。

    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]

FL5.12 cells suspended in EMB growth medium containing 4% fetal bovine serum (FBS) are incubated at 37°C for 1 hour in 10 μM A-385358. Compound concentration is determined by high-performance liquid chromatography before and after the 1-hour incubation following brief centrifugation. To analyze membrane-bound fractions following compound incubation, cells are washed once with 10 volumes of cold PBS and lysed with 4 mL of water. A-385358 concentration is determined from aliquots of lysate before and after centrifugation[1].

MCE has not independently confirmed the accuracy of these methods. They are for reference only.
Cell Assay
[1]

A549 cells (1×105) are plated in 96-well plates in medium containing 10% fetal bovine serum. Following attachment, A-385358 is added to one set of wells (final concentration of 50 μM in 10% FBS) and medium is added to another set. [3H]Paclitaxel (5 μM; 0.5 μCi/mL final concentration) is added to all wells and the cells are incubated at 37°C for various periods of time. For washout experiments, cells are exposed first to [3H]paclitaxel for 2 hours. The cells are washed once with medium and then incubated with fresh medium with or without 50 μM A-385358 at 37°C for various periods of time[1].

Animal Administration
[1]

For efficacy studies, male CD-1 nude mice are inoculated with a 1:5 dilution of tumor brei in 50% Matrigel and analysis is conducted. A-385358 is delivered in a vehicle containing 5% Tween 80, 20% propylene glycol, and 75% PBS (pH 3.8). Paclitaxel is formulated according to the recommendations of the manufacturer. For combination therapy of paclitaxel plus A-385358, both drugs are administered i.p. with the paclitaxel given several hours before treatment with A-385358 (except for immunohistochemistry studies looking at expression of MPM-2 and caspase-3 wherein the two drugs are given simultaneously)[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.
