PFI-3 是一种有效的细胞活性 BRG/PB1 bromodomains 抑制剂，Kd 为 54-97 nM。

PFI-3 is a potent and cell active BRG/PB1 bromodomains inhibitor with Kd of 54-97 nM; shows high selectivity over other bromodomains; exposure of embryonic stem cells to PFI-3 led to deprivation of stemness and deregulated lineage specification; markedly enhances the differentiation of trophoblast stem cells; attenuates adipocyte differentiation and dramatically decreases lipid accumulation; a first in class chemical probe for Family VIII bromodomains.

PFI-3 is a potent, cell-permeable probe capable of displacing ectopically expressed, GFP-tagged SMARCA2-bromodomain from chromatin. PFI-3 binds avidly to both SMARCA2 and SMARCA4 bromodomains (BROMOScan Kd's between 55 and 110 nM) consistent with the binding constant (Kd=89 nM) measured by isothermal titration calorimetry. PFI-3 does not phenocopy the growth inhibitory effects of SMARCA2 knockdown in lung cancer. Exposure of embryonic stem cells to PFI-3 leads to deprivation of stemness and deregulates lineage specification. Furthermore, differentiation of trophoblast stem cells in the presence of PFI-3 is markedly enhanced. PFI-3 binds to certain family VIII bromodomains while displaying significant, broader bromodomain family selectivity. The high specificity of PFI-3 for family VIII is achieved through a novel bromodomain binding mode of a phenolic headgroup that leads to the unusual displacement of water molecules that are generally retained by most other bromodomain inhibitors reported to date.
