Abstract: DNA methylation, an epigenetic modification regulating gene expression, is a promising target in cancer. In an effort to identify new non nucleosidic inhibitors of DNA methyltransferases, the enzymes responsible for DNA methylation, we carried out a high-throughput screening of 66,000 chemical compounds based on an enzymatic assay against catalytic DNMT3A. A family of propiophenone derivatives was identified. After chemical optimization and structure activity relationship studies, a new inhibitor (33) was obtained with an EC50 of 2.1 μM against DNMT3A. The mechanism of inhibition of the compound was investigated as it forms a reactive Michael acceptor group in situ. Thereby, the Michael acceptor 20 was identified. This compound was further characterized for its biological activity in cancer cells.
