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 .
In Vitro
Thailanstatin A (TST-A) is a potent antiproliferative natural product, can be discovered from Burkholderia thailandensis MSMB43. ?\nThailanstatin A (DU-145, NCI-H232A, MDA-MB-231 and SKOV-3 cells) exhibits potent antiproliferative activities with GI 50 s in the single nM range (1.11-2.69 nM). MCE has not independently confirmed the accuracy of these methods. They are for reference only.

生化机理
Thailanstatin A 是一种超强的真核 RNA 剪接抑制剂(IC 50 =650 nM)。Thailanstatin A 通过与剪接体 U2 snRNA 亚复合物的 SF3b 亚基的非共价结合来发挥效应,对 RNA 剪接的 IC 50 s 的抑制作用在低-nM 到亚-nM 之间。
