On target activity in cells

Potency in cells:

EC50 (% effect)

GAL4 LXRβ 3.67 uM (73), GAL4 LXRα 6.66 uM (53), ABAC1 0.53 uM (100), C-Efflux 1.27 uM (140), SREBP1 2.11 uM (58), Lipid acc. 1.91 uM (35)

Potency assay (cells):

Huh-7 human hepatoma cell based Gal4 LXRα or LXRβ transactivation assay, Cell functional assay for gene expression.

Target engagement assay (cells):

Several candidate biomarkers of LXR agonist exposure and activity have been identified in peripheral blood, and two of these (ABCA1 and ABCG1) have been demonstrated to change substantially (up to 200 fold change) and rapidly (≤ 4 hours) upon compound treatment.

Off target activity in cells

Probe Selectivity in Cell:

PPAR and FXR Gal4 transactivation assays show no agonist effects for PPARα, PPARγ, PPARδ and FXR. Binding Assays: PXR 1.77 uM, RXR >10 uM, GR 1.0 uM, MR no binding, AR2.3 uM, PR >1 uM, ERα No binding, ERβ No binding, TRα No binding, TRβ No binding
