In vitro activity: In HEK293 cells expressing LXRs, SR9243 inhibits LXR activation by enhancing LXR-corepressor recruitment. In a variety of cancer cell types, SR9243 reduces cancer cell viability, induces apoptotic cell death, and sensitizes cancer cells to chemotherapeutic treatments.

Cell Assay: Cells are cultured in 96 well plates and treated with designated amounts of SR9243 for 96 hr in media containing 1% FBS and antibiotics. Cell-viability is assessed using the Cell-titre 96 kit according to the manufacturer’s guidelines. Cell culture media is supplemented with oleate, stearate and palmitate dissolved in methanol to a concentration of 25 mM. 25 mM stocks are then diluted 10 fold in PBS containing 0.9% BSA. Lipid stocks (100X) are stored at –20° until needed.
