Thailanstatin A

Catalog No. T38889 CAS 1426953-21-0

Thailanstatin A is an ultra-potent inhibitor of eukaryotic RNA splicing (IC50 =650 nM). Thailanstatin A inhibits multiple cancer cell lines 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 . Thailanstatin A, a payload for ADCs, is conjugated to the lysines on trastuzumab yielding “linker-less” ADC.

Description	Thailanstatin A is an ultra-potent inhibitor of eukaryotic RNA splicing (IC50 =650 nM). Thailanstatin A inhibits multiple cancer cell lines 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 . 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 discovered by our group from Burkholderia thailandensis MSMB43 [2]. Thailanstatin A (DU-145, NCI-H232A, MDA-MB-231 and SKOV-3 cells) shows potent antiproliferative activities with GI 50 s in the single nM range (1.11-2.69 nM) [3].
