In Vitro | In vitro activity: PFI-1 binds to with cyclic AMP response binding protein with KD of 49 μM. PFI-1 has an EC50 of 1.89 μM for the inhibition of IL6 production from human blood mononuclear cells stimulated by LPS. PFI-1 induces dose-dependent reduction of cell viability in T4302 CD133+ cells. PFI-1 inhibits the proliferating of three NET cell lines (Bon-1 derived from a pancreatic NET, and H727 and H720 derived from lung NETs). Kinase Assay: PFI-1 is a selective BET (bromodomain-containing protein) inhibitor for BRD4 with IC50 of 0.22 μM in a cell-free assay. Cell Assay: To determine dose response, cells are aliquoted into 96-well plate at 5 × 103 cells per well in triplicates. PFI-1 is added by 2- or 4-fold serial dilutions. Cell number is measured 5 days after plating using the CellTiter-Glo Kit and normalized to corresponding vehicle-treated groups. IC50 values are calculated by the GraphPad Prism 5 software using the 4-parameter logistic nonlinear regression model. To calculate the relative growth of cells, averaged cell titers of each group on day 1 are assigned a value of 1. All subsequent cell titer values are normalized accordingly. |

In Vivo | PFI-1 administrated (1 mg/kg i.v.) in the rat results in the volume of distribution of 1 L/kg, the plasma clearance of 18/mL·min–1·kg–1 and half-life of 1 hour. PFI-1 oral dosed (2 mg/kg) in the rat results in the oral bioavailability as low as 32%. PFI-1 administrated (2 mg/kg s.c.) in the mouse results in a Cmax of 58 ng/mL with a Tmax of 1 h and a half-life of approximately 2 hours. |
