LP99 is a novel BRD7 and BRD9 specific inhibitor.

LP99 is a potent and selective bromodomain BRD9 and BRD7 inhibitor with a higher potency for BRD9 (Kd = 99 nM) than for BRD7 (Kd = 909 nM), and no inhibition for any of the 48 other BRDs tested. LP99 was shown to disrupt BRD7 and BRD9 binding to chromatin in cells. LP99 also inhibited interleukin 6 (IL-6) secretion, suggesting that BRD7/9 plays a role in the regulation of pro-inflammatory cytokine secretion. LP99 is not cell cytotoxic up to 25 μM.
