Biological Activity

Description SR-12813 is a pregnane X receptor (PXR) agonist and HMG-CoA reductase inhibitor with an IC50 of 850 nM.
Targets
pregnane X receptor [1] HMG-CoA reductase [2]
850 nM
In vitro SR12813 is a very potent and efficacious activator of both the human and rabbit PXR, with EC50 values of approximately 200 nM and 700 nM, respectively. By contrast, SR12813 is only a very weak activator of the rat and mouse PXR[1]. SR-12813 inhibits incorporation of tritiated water into cholesterol with an IC50 of 1.2 μM but has no effect on fatty acid synthesis. SR-12813 reduces cellular 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase activity with an IC50 of 0.85 μM. The inhibition of HMG-CoA reductase activity is rapid with a T1/2 of 10 min[2].
In vivo The bisphosphonate ester SR12813 lowers cholesterol levels in a range of species including rats, dogs and primates[1].
