Background:

BRD9539 inhibits G9a activity with an IC50 of 6.3 μM, inhibits PRC2 activity with a similar IC50.target: G9a, PRC2;IC50: 6.3 μM ( G9a ), 6.3 uM ( PRC2 ); 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.
