Biological Activity

Description

PFI-1 (PF-6405761) is a highly selective BET (bromodomain-containing protein) inhibitor for BRD4 with IC50 of 0.22 μM and for BRD2 with IC50 of 98 nM in a cell-free assay.

Targets

BRD2 ^[4] (Cell-free assay)	BRD4 ^[1] (Cell-free assay)
98 nM	0.22 μM

In vitro
In vitro	PFI-1 binds to with cyclic AMP response binding protein with K_D 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. ^[1] PFI-1 induces dose-dependent reduction of cell viability in T4302 CD133+ cells. ^[2] 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). ^[3]
Cell Research	Cell lines	T4302 CD133+ cells
	Concentrations	1 mM
	Incubation Time	5 days
	Method	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
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 C_max of 58 ng/mL with a T_max of 1 h and a half-life of approximately 2 hours. ^[1]

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
