BI 2536 | Dual Plk/BRD4 inhibitor - Destabilizes Myc

BI 2536 (755038-02-9) was originally reported as a potent (IC50’s Plk1 = 0.83nM, Plk2 = 3.5nM and Plk3 = 9.0nM)1 and selective2 Polo-like kinase inhibitor that caused mitotic arrest and apoptosis induction in various human cancer cell lines.1 It was later found to be a potent inhibitor (IC50 = 100nM) of BET family member BRD4 and able to potently suppress c-Myc expression in MM.1S multiple myeloma cells.3 BI 2536 destabilizes N-Myc by inhibiting the deactivation of the ubiquitin E3 ligase Fbw7 by Plk1.4
