| Biochem/physiol Actions: |
I-BET762 (GSK525762) is a selective inhibitor of bromodomain and extra terminal (BET) domain proteins BRD2, BRD3 and BRD4 with IC50 values of 32.5–42.5 nM and no interaction with other bromodomain-containing proteins. I-BET mimicks acetylated histone, preventing the protein-protein interaction between acetyl-lysines and the BET reader protein. This was shown to block expression of inflammatory genes in activated macrophages and confer protection against endotoxic shock and bacterial sepsis. I-BET762 also showed potent anti-myeloma activity in vitro and in vivo. |
| Biochem/physiol Actions: |
I-BET762 is a selective inhibitor of bromodomain and extra terminal (BET) domain proteins; synthetic histone mimic. |
| Biochem/physiol Actions: |
I-BET762 possesses anti-inflammatory property by controlling the pro-inflammatory gene expression. I-BET762 hinders the MYC (proto-oncogene) expression in cellular models. This action of I-BET762 might serve as an effective therapy in treating prostate cancer. |
