TP-238 hydrochloride is a highly potent and selective dual CECR2 BPTF probe, demonstrating IC50 values of 30 nM and 350 nM, respectively. It additionally exerts inhibitory effects on BRD9, with a pIC50 value of 5.9, while displaying lower activity against 338 other kinases.
BAZ2-ICR is an epigenetic chemical probe and it also is a potent, selective, cell active and orally active BAZ2A B bromodomains inhibitor with IC50s of 130 nM and 180 nM, and Kds of 109 nM and 170 nM, respectively. BAZ2-ICR shows 10-15-fold selectivity for binding BAZ2A B over CECR2 and >100-fold selectivity over all other bromodomains.
