QC6352 is a potent KDM4C inhibitor with an IC50 of 35±8 nM[1]. In a concentration-dependent manner QC6352 dramatically reduces the sphere-forming capacity of BCSC1 and BCSC2. QC6352 blocks proliferation and self-renewal of BCSCs. As shown by western blot analysis the protein levels of (Epidermal growth factor receptor) EGFR are reduced in both BCSC1 and BCSC2 upon treatment with QC6352[2].

Protocolo
Cells are detached by Accutase and counted. 1×103 single BCSC1 and BCSC2 cells are seeded as triplicates in 50% Matrigel into individual wells of 24-well ultra-low attachment plates in serum-free MSC medium. After 7 days, spheres over 50 μm diameter are counted for QC6352- and QC6688-treated and control cells and spheres over 20 μm diameter are counted for paclitaxel-treated and control cells[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
Mice: When tumors reach a palpable size of 3 mm3, mice are treated with vehicle (control) or QC6352. The inhibitor is administered daily to mice via oral gavage at 10 mg/kg. Control animals receive vehicle only. Animals are monitored twice weekly for weight and tumor growth[2].
