    Product Description

    FQI 1 is an inhibitor of Late SV40 Factor (LSF) transactivation activity (IC50 = 2.1 µM).1 It inhibits growth of NIH3T3, HeLa S3, and A549 cancer cells (GI50s = 3.8, 0.79, and 6.3 µM, respectively). FQI 1 decreases viability of QGY-7703 and Huh7 liver cancer cells, but not of non-cancerous Hc3716-hTERT cells and primary mouse hepatocytes, when used at a concentration of 4 µM.1,2 It reduces tumor growth induced by N-nitrosodiethylamine (DEN) in mice and in a QGY-7703 hepatocellular carcinoma (HCC) mouse xenograft model when administered at doses of 4 and 1 mg/kg, respectively.

    WARNING This product is not for human or veterinary use.
