  Dual Inhibition of TAF1 and BET Bromodomains from the BI-2536 Kinase Inhibitor Scaffold

  摘要：

  Recent reports have highlighted the dual bromodomains of TAF1 (TAF1(1,2)) as synergistic with BET inhibition in cellular cancer models, engendering interest in TAF/BET polypharmacology. Here, we examine structure activity relationships within the BI-2536 PLK1 kinase inhibitor scaffold, previously reported to bind BRD4. We examine binding by this ligand to TAF1(2) and apply structure guided design strategies to discriminate binding to both the PLK1 kinase and BRD4(1) bromodomain while retaining activity on TAF1(2). Through this effort we discover potent dual inhibitors of TAF1(2)/BRD4(1), as well as biased derivatives showing marked TAF1 selectivity. We resolve X-ray crystallographic data sets to examine the mechanisms of the observed TAF1 selectivity and to provide a resource for further development of this scaffold.

  inhibition of polo-like kinase 1 (PLK1) and BRD4 bromodomain by a single molecule could lead to the development of an effective therapeutic strategy for a variety of diseases in which PLK1 and BRD4 are implicated. Compound 23 has been found to be a potent dual kinase-bromodomain inhibitor (BRD4-BD1 IC50 = 28 nM, PLK1 IC50 = 40 nM). Compound 6 was found to be the most selective PLK1 inhibitor over BRD4

  The present invention provides a means to modulate gene expression in vivo in a manner that avoids problems associated with CRISPR endogenous protein knock-out or knock-in strategies and strategies that provide for correction, or alteration, of single nucleotides. The invention includes inserting into the genome a nucleotide encoding a heterobifunctional compound targeting protein (dTAG) in-frame with the nucleotide sequence of a gene encoding an endogenously expressed protein of interest which, upon expression, produces an endogenous protein-dTAG hybrid protein. This allows for targeted protein degradation of the dTAG and the fused endogenous protein using a heterobifunctional compound.

  Take two: A design strategy for the development of polo‐like kinase 1 (Plk1) inhibitors incorporating both an inhibitor of the enzymatic domain and an inhibitor of the polo‐box domain (PBD) is reported. The most potent inhibitor displays low‐nanomolar activity against the Plk1 PBD and excellent selectivity over the PBDs of Plk2 and Plk3.
