LM146 (LM-146) is a potent and selective inhibitor of pan-PB1 bromodomains (Polybromo-1 protein, PBRM1 or BAF180), binds to PB1(2), PB1(5), and SMARCA2B with KD values of 110, 61, and 2100 nM, respectively.LM146 displayed 34-fold selectivity profile for PB1(5) over SMARCA2, showed no binding to any bromodomains outside the sub-family VIII at 10 uM.PB1 (Polybromo-1 protein) is a component of the BRG1/BRM-associated factor (PBAF) complex, a human analog of the yeast switch/sucrose non-fermenting (SWI/SNF) complex. PB1 is a unique epigenetic reader that contains six distinct bromodomains, while other known bromodomain-containing proteins possess at most two bromodomains. The multi-subunit PBAF complex contains three bromodomain-containing proteins (BCPs): BRD7, a member of the sub-family IV, and SMARCA4 (also known as BRG1) and PB1, two members of the sub-family VIII.
