thailanstatin a

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.
