| In vitro study | PFI-3 selectivity for PB1(5) and SMARCA2/4 was significantly higher than the 36 other kinases tested. PFI-3 was significantly more selective for PB1(5) and SMARCA2/4 than the 36 other kinases tested. PFI-3 is a potent, cell-active inhibitor of protein interactions that selectively binds to the basic BAF bromine region. In a screening experiment with 102 cell receptors and 30 enzymes, PFI-3 had micromolar affinity for only four GPCRs and no interaction with proteins outside the BRD family, it shows that PFI-3 has good drug selectivity. Stability testing demonstrated that the half-life of PFI3 in liquid solutions was more than 7 days at 37 °c. In long-term experiments, PFI-3 were able to significantly alter gene expression programs critical to stem cell differentiation. PFI-3 can mimic the effect of Brg1 deletion, causing an increase in the inhibitory H3K27me3 marker, Gene Stat3 binding site, in TSSs. PFI-3 in 20 C, pH7.4 PBS, the half-life of more than 250 h. |

PFI-3 is an effective and cell-active protein interaction inhibitor that can selectively bind to the basic BAF bromine region. In the screening experiment with 102 kinds of cell receptors and 30 kinds of enzymes, PFI-3 has only micro-molar affinity for four GPCRs and has no interaction with proteins outside BRD family, indicating that PFI-3 has good drug selectivity. The stability test proved that PFI3 had a half-life of more than 7 days in liquid solution at 37°C. In long-term experiments, PFI-3 can significantly change the gene expression program that is essential for stem cell differentiation. PFI-3 can simulate the effect of Brg1 deletion and cause the increase of inhibitory H3K27me3 markers and Stat3 binding sites in TSSs. PFI-3 in PBS at 20 ℃ and pH7.4, the half-life is more than 250 h. |
