QC6352 is an inhibitor of lysine demethylase 4 (KDM4).1 It is selective for the KDM4 isoforms KDM4A, KDM4B, KDM4C, and KDM4D (IC50s = 104, 56, 35, and 104 nM, respectively) over KDM2B, KDM3A, KDM3B, KDM6B, and PHD finger protein 8 (PHF8; IC50s = >4,000 nM for all) but does inhibit KDM5B (IC50 = 750 nM). QC6352 increases trimethylation of lysine 36 on histone H3 (H3K36Me3) in KYSE-150 esophageal carcinoma cells overexpressing KDM4C (EC50 = 1.3 nM). It reduces the proliferation of KYSE-150 cells (EC50 = 3.5 nM) but not IMR-90 fibroblasts (IC50 = >30 µM). QC6352 (10, 25, and 50 mg/kg) reduces tumor volume in a BR0859f patient-derived xenograft (PDX) mouse model of HER2-positive breast cancer.
