Overview

Information

TK216 TK216 is a potent inhibitor targeting E26 transformation specific (ETS) factors via blocking the protein-protein interaction with RNA helicases. TK216 exhibits antilymphoma activity.


Targets

ETS


In vitro

TK-216 demonstrates an antitumor activity across several lymphoma cell lines. Synergistic activity is observed when TK-216 is combined with the BCL2 inhibitor venetoclax and with the immunomodulatory drug lenalidomide.


In vivo

TK-216 demonstrates an antitumor activity in vivo. TK-216 interferes with protein interactions of ETS family members SPIB, in activated B-cell–like type diffuse large B-cell lymphomas, and SPI1, in germinal center B-cell–type diffuse large B-cell lymphomas.
