  • PubMed Abstract: 

    Histone lysine demethylases (KDMs) play a key role in epigenetic regulation and KDM5A and KDM5B have been identified as potential anti-cancer drug targets. Using structural information from known KDM4 and KDM5 inhibitors, a potent series of pyrazolylpyridines was designed. Structure-activity relationship (SAR) exploration resulted in the identification of compound 33, an orally available, potent inhibitor of KDM5A/5B with promising selectivity. Potent cellular inhibition as measured by levels of tri-methylated H3K4 was demonstrated with compound 33 in the breast cancer cell line ZR-75-1.
