Description
|
GW4064 is an agonist of farnesoid X receptor (FXR) with EC50 of 65 nM.
|
|
Targets
|
FXR [1]
|
|
IC50
|
65 nM(EC50)
|
|
In vitro
|
GW 4064 is a full agonist with EC50 values of 80 and 90 nM, respectively, in CV-1 cells transfected with mouse and human FXR expression vectors and an established reporter gene. There is no activity of GW 4064 on other nuclear receptors, including the retinoic acid receptor, at concentrations up to 1 μM. Thus, GW 4064 is a potent and selective nonsteroidal FXR agonist.
|
|
In vivo
|
Pharmacokinetic analysis in rats shows that GW 4064 possesses an oral bioavailability of 10% with a t1/2 = 3.5 h. Fisher rats are dosed with GW 4064 by oral gavage. After 7 days, a dose-dependent lowering of serum triglycerides is observed in the rats receiving GW 4064, with an ED50 = 20 mg/kg.

FXR Transient Transfection Assay
|
CV1 cells are maintained in DMEM high glucose medium. The CV1 cells are harvested 72 hours before transfection and plated in DMEM-F12 phenol red free medium containing 5% charcoal/dextran treated fetal bovine serum and 2 mM glutamine. On the day of transfection, the CV1 cells are harvested in DMEM-F12 phenol red free medium containing 5% charcoal/dextran treated fetal bovine serum and 2 mM glutamine, counted and seeded into a T-175 cm2 flask at a density of 14 million cells per flask before adding the transfection mix. The FuGENE® 6 transfection mix containing 0.55 μg pFA-CMV-GAL4-human FXR LBD expression plasmid, 10.92 μg of the (UAS)-tk-Luciferase reporter plasmid, 20.75 μg of pBluescript II KS+, and 3.82 μg of a human steroid receptor co-activator (SRC-1) construct is incubated and then added to the CV1 cells for overnight incubation in incubator. The transfected CV1 cells are harvested in DMEM-F12 phenol red free medium containing 5% charcoal/dextran treated fetal bovine serum and 2 mM glutamine. Transfected cells are added at a concentration of 3750 cells/well to 384-well plates containing ligands. Luciferase expression is measured using Steady-Glo?Luciferase Assay System 24 hr after incubation with ligand. GW4064X is used as the control, and data are normalized to GW4064X as % control.

Um beispielsweise die Resveratrol-Dosis für eine Maus (22,4 mg/kg) auf eine Dosis basierend auf dem BSA für eine Ratte zu ändern, multiplizieren Sie 22,4 mg/kg mit dem Km-Faktor für eine Maus und dividieren Sie dann durch den Km-Faktor für eine Ratte. Diese Berechnung ergibt eine Ratten-Äquivalentdosis für Resveratrol von 11,2 mg/kg.
