Description

General description

A cell-permeable benzimidazolyl-benzimidazolothione that targets BD1 (bromodomain 1) of the BET (bromodomain and extra terminal domain) family member BRD2 (K_d = 28 µM in equilibrium binding studies by SPR, using human BRD2 aa 74-194), making it inaccessible for acetylated H4K12 (histone H4 Lys12) binding. Shown to effectively inhibit TSA- (Cat. No. 647925; 1 h 1 µM) induced BRD2 BD1-H4K12 association in COS7 cells (59% and 100% inhibition, respectively, by 10 and 60 µM BIC1) and greatly suppress active Ras-induced SV40 promoter transcriptional activation in RasV12-transfected HeLa cells (70% inhibition by 5 µM BIC1), while being much less effective against BRDT BD1 and acetylated H4K5/K8 interaction in TSA-stimulated COS7 cells (Maximum inhibition = 47% by 60 µM BIC1).
