GW3965 has an EC₅₀ = 125 nM in a cell-free ligand-sensing assay of LXRα and profiles as a full agonist on hLXRα and hLXRβ in cell-based assays with EC₅₀ = 190 nM and 30 nM, respectively. Up-regulates ABCA1 gene expression and raises circulating HDL levels. Displays potent antiatherogenic activity in mouse models of atherosclerosis.
