产品详情
Thailanstatin A 是一种有效的真核 RNA 剪接 (RNA splicing) 抑制剂 (IC50=650 nM)。Thailanstatin A 通过非共价结合到剪接体的 U2 snRNA 亚复合物的 SF3b 亚单位发挥作用,并且对多种癌细胞系显示低 nM 到亚 nM 的 IC50 值。Thailanstatin A 与 Trastuzumab 上的赖氨酸结合,可产生“无连接子 (linker-less)” ADC。
生物活性
Thailanstatin A is an ultra-potent inhibitor of eukaryotic RNA splicing (IC 50 =650 nM). Thailanstatin A exerts effects via non-covalent binding to the SF3b subunit of the U2 snRNA subcomplex of the spliceosome and shows low-nM to sub-nM IC 50 s against multiple cancer cell lines. Thailanstatin A, a payload for ADCs, is conjugated to the lysines on trastuzumab yielding “linker-less” ADC.

体外研究(In Vitro)
Thailanstatin A (TST-A) is a potent antiproliferative natural product discovered by our group from Burkholderia thailandensis MSMB43.
Thailanstatin A (DU-145, NCI-H232A, MDA-MB-231 and SKOV-3 cells) exhibits potent antiproliferative activities with GI50s in the single nM range (1.11-2.69 nM). has not independently confirmed the accuracy of these methods. They are for reference only.

1:一般建议:溶解度为Medlife测试数据,可能与文献描述存在差异。这是由于生产工艺和批次不同产生的正常现象。为了使其更好的溶解,请用37℃加热试管并在超声波水浴中震动片刻。不同批次产品溶解度各有差异,仅做参考,具体以实验方案为准。

2:储存条件:粉末-20°C一般情况可以保存3年,溶于溶剂-80°C一般情况可以保存1年。不同产品及不同批次产品可能存在差异,请细致阅读产品信息,并辅助参考相关文献描述。

The molarity calculator equation
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
The dilution calculator equation
Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2
