Design, synthesis, inhibitory activity, and binding mode study of novel DNA methyltransferase 1 inhibitors

To identify novel non-nucleoside DNA methyltransferase (DNMT) inhibitors, we designed and synthesized a series of maleimide derivatives. Among this series, compounds 5–8 were found to be more potent DNMT1 inhibitors than RG108, a DNMT1 inhibitor reported previously by Siedlecki et al. The binding mode analysis of compound 5 is also reported.
