I-BET762 (GSK525762A) is a potent BET bromodomain inhibitor, as well as a downregulator of the critical oncogene, MYC (1,5). This small molecule inhibits binding of acetylated histones to BET proteins, disrupting the expression of inflammatory genes in activated macrophages, as well as blocking acute inflammation in mice (2,3). Studies have found that I-BET762 (GSK525762A) suppressed T cell inflammation resulting in upregulated expression of anti-inflammatory gene products, and downregulated expression of several proinflammatory cytokines (3). I-BET762 (GSK525762A) has also been shown to induce cell death and suppress cell proliferation in pancreatic ductal adenocarcinoma (PDAC) cells (4).
