  • PubMed Abstract: 

    The discovery and optimization of a novel series of G9a/GLP (EHMT2/1) inhibitors are described. Starting from known G9a/GLP inhibitor 5, efforts to explore the structure-activity relationship and optimize drug properties led to a novel compound 13, the side chain of which was converted to tetrahydroazepine. Compound 13 showed increased G9a/GLP inhibitory activity compared with compound 5. In addition, compound 13 exhibited improved human ether-a-go-go related gene (hERG) inhibitory activity over compound 5 and also improved pharmacokinetic profile in mice (oral bioavailability: 17 to 40%). Finally, the co-crystal structure of G9a in complex with compound 13 provides the basis for the further development of tetrahydroazepine-based G9a/GLP inhibitors.
