MS436 is a potent and selective BET bromodomain inhibitor with Ki of <0.085 μM and 0.34 μM for BRD4 (1) and BRD4 (2), respectively. It effectively inhibits BRD4 activity in NF-κB-directed production of nitric oxide and proinflammatory cytokine interleukin-6 in murine macrophages without siginificanty inhibition on cell viability. MS436 represents a new class of bromodomain inhibitors to study the functional differences of the two bromodomains of BRD4
