Sulfo-SPDB-DM4 is a drug-linker conjugate designed for antibody-drug conjugates (ADCs) that employs the maytansine-based payload (DM4, an antitubulin agent) connected through the sulfo-SPDB linker.

MC-Val-Cit-PAB-Sunitinib is a conjugate composed of the payload Sunitinib and a linker. It is utilized in the synthesis of HR97-Sunitinib.

Thailanstatin A is an ultra-potent inhibitor of eukaryotic RNA splicing (IC50 = 650 nM). It inhibits multiple cancer cell lines via non-covalent binding to the SF3b subunit of the U2 snRNA subcomplex of the spliceosome, displaying low-nM to sub-nM IC50s. Thailanstatin A, as a payload for ADCs, is conjugated to the lysines on trastuzumab, yielding linker-less ADC.
