Dual-Site Covalent Targeting Enables BD2-Selective BET Inhibition With Potent Antitumor Activity in Mice.
Bromodomain and extra-terminal (BET) proteins are validated therapeutic targets for cancer, but clinical translation of pan-BET inhibitors is limited by dose-limiting toxicities from non-selective inhibition of BD1/BD2 domains. Herein, we report the first-ever domain-selective covalent inhibitor, named ipAE1, of BET BD...
