SR-9243
SR9243 is a liver-X-receptor (LXR) inverse agonist that induces LXR-corepressor interaction. It potently reduces cancer cell viability (IC50=15–104 nM) in MTT reduction assays in prostate (PC3 and DU-145), colorectal (SW620 and HT29), and lung (HOP-62 and NCI-H23) cancer cell lines. [1]
LXR (liver X receptor) is a member of the nuclear receptor family of transcription factors. It is an important regulator of glycolysis and lipogenesis enzyme expression.
In SW620 cells, 1 mM SR9243 treatment for 12 hours induces cell death with a robust increase in caspase 3/7 activation. In addition, SR9243 disrupts the Warburg effect, suppresses lipogenesis gene expression and lipid production in cancer cells without effecting normal cells. [1]
In colon tumor xenograft, SR9243 substantially and dose-dependently reduces tumor growth, glycolytic (GCK1, PFK2, PFK1 and LDH) and lipogenic (SCD1, FASN, and SREBP1c) enzyme expression without promoting weight loss. SR9243 also blocks tumor growth without causing immune or hepatic toxicity in vivo. [1]

|
Applications |
In athymic mice bearing SW620 colon cancer xenografts, SR-9243 substantially reduced the growth of colon cancer xenografts in a dose-dependent manner. Meanwhile, SR-9243-treated tumor-bearing mice did not show any weight loss. |

Other notes |
Please test the solubility of all compounds indoor, and the actual solubility may slightly differ with the theoretical value. This is caused by an experimental system error and it is normal. |
