ATAD2 and ATAD2B are epigenetic regulators known to function as co-factors for oncogenic transcription factors. ATAD2 overexpression correlates with poor outcomes in several cancers. The bromodomain module of ATAD2 has been shown to be essential for its association with acetylated chromatin and presumable function.
BAY-850 is a chemical probe for the ATAD2A bromodomain which displaces acetylated H4 peptide from the ATAD2 bromodomain with an IC50 value of 20 nM (HTRF). MST and BROMOscan measurements indicate a Kd of 84.9 nM and 120 nM, respectively. BAY-850 displays exquisite selectivity over all other bromodomains (no hits in BROMOscan at 10 µM) and displaces full-length ATAD2 from chromatin in live cells at a concentration of 1 µM as determined by FRAP. To avoid potential unspecific off-target effects concentrations of ≥ 5 µM are not recommended.
BAY-460 is a companion control compound with strongly reduced potency against ATAD2 (HTRF IC50 = 16 µM, no activity in BROMOscan at 10 µM test concentration).
