Zeste enhancer homolog 2 (EZH2) is highly expressed in various malignant tumors, which could silence tumor suppressor genes via trimethylation of H3K27. Herein was first reported a novel series of pyrrole-3-carboxamide derivatives carrying a pyridone fragment as EZH2 inhibitors. By combining computational modeling, in vitro cellular assays and further rational structure-activity relationship exploration and optimization, compound DM-01 showed powerful inhibition towards EZH2. DM-01 was found to have significant ability to reduce the cellular H3K27me3 level in K562 cells in the Western blot test. Meanwhile, our data showed that knockdown EZH2 in A549 cells resulted in a decrease of cell sensitivity to DM-01 at 50 and 100 μM. DM-01 could also increase the transcription expression of DIRAS3 in a dose-dependent manner, a tumor suppressor in the downstream of EZH2, suggesting it was worth investigating further as a lead compound.

Paragraph 0017-0026, (2019/04/17)
The invention relates to a compound preparation method. Organic solvents and sodium methylate are added into a reaction vessel, carbon monoxide is led into the reaction vessel to perform reaction, acetone and organic solvent mixed solution is dropped after reaction to continue reaction to generate an intermediate sodium salt as shown in a formula I, the intermediate sodium salt reacts with dimethylamine to generate 4-N, N-dimethyl butene-3-ketone as shown in a formula II. Synthesis steps can be finished in one vessel, and the compound preparation method is low in cost and suitable for industrialization production.
