BRD9539

BRD9539 decreases ATP levels in a dose-dependent manner in HeLa cells.
BRD9539 is a more potent biochemical inhibitor than its methyl-ester analogue BRD4770, with 20% remaining G9a activity compared to 45% of BRD4770 at screening concentration. However, BRD9539 has no activity in cell-based assays, presumably due to impaired cell permeability compared to that of BRD4770. In addition, the activities of 16 other chromatin-modifying enzymes and 100 kinases involved in cell-cycle regulation and cancer cell biology are tested for activity in the presence of 5 or 10 μM BRD9539; no activity is seen in any of these assays.
