Biochem/physiol Actions

I-BET432 is a bromodomain (BrD) inhibitor with selectivity toward the BET family of bromodomain-containing proteins (BrD1/2 pKd = 8.3/8.1 (BRD2), 8.5/8.1 (BRD3), 8.3/8.2 (BRD4), 8.3/7.8 (BRDT) by DiscoRx BROMOscan) with little or no affinity toward bromodomain-containng proteins (BCPs) and BrDs, including CREBBP, TRIM24, EP300, WDR9 BD2, PBRM1 BD2, TAF1 BD2, BAZ2A (pKd <5.9 from DiscoRx BROMOscan panel). I-BET432 inhibits LPS-stimulated MCP-1 production from human white blood cells (pIC50 = 7.4) with oral availability and good in vivo pharmacokinetic properties.
