GSK 525768A is the inactive stereoisomer of I-BET-762 which is a selective inhibitor of BET family with IC50 value of 35 nM [1].
BET (bromodomain and extra-terminal domain) has 4 members, BRD2, BDR3, BRD4 and BRDT and plays an important role in regulating transcription. It has been shown that BET involves in the process of suppressing proinflammatory cytokines production by macrophages and has potent anti-proliferative effects on tumor cells [2].
I-BET-762 is a potent BET inhibitor and suppresses macrophage-derived proinflammatory cytokines production [1]. When tested with naïve CD4+ T cells, I-BET-762 treatment for short 2-d up-regulated anti-inflammatory cytokines production (IL-10, Lag 3 and Egr2) and down-regulated proinflammatory cytokines production (GM-CSF and IL-17) constantly [3].
When tested with LPS-treated C57BL/6 mice, administration with I-BET-762 (5 mg per kg, i.p.) significantly suppressed LPS-induced acute inflammation compared with control GSK 525768A treated group [1]. In adoptive transfer of EAE mouse model with 2D2 T cell receptor that producing IL-17, pretreated T cells with I-BET-762 suppressed T cell mediated inflammation and decreased macrophages recruitment compared with GSK 525768A treatment [3].
