Biological Activity

In vitro: BAR 501 is a selective GPBAR1 agonist devoid of FXR agonistic activity. It effectively transactivates GPBAR1 in HEK293 cells overexpressing a CRE along with GPBAR1, with an EC50 of 1 μM. Exposure of GLUTAg cells to BAR501 (10 μM) increases the expression of GLP-1 mRNA by 2.5 folds.

In vivo: Pretreating rats for 6 days with BAR501, 15 mg/kg, reduces basal portal pressure and blunts the vasoconstriction activity of norepinephrine. Pretreatment with BAR501 attenuates the hepatic vasomotor activity induced by shear stress and methoxamine. Administration of BAR501 exerts a direct vasodilatory activity in the CCl4 model. Treating mice with BAR501 at the dose of 15 mg/Kg reduces portal pressure and AST plasma levels. BAR501 attenuates endothelial dysfunction by regulating CSE expression/activity.

Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.
