Design, Synthesis and Biological Activities of Pyrrole-3-carboxamide Derivatives as EZH2 (Enhancer of Zeste Homologue 2) Inhibitors and Anticancer Agents

Abstract

Zeste enhancer homolog 2 (EZH2) is highly expressed in various malignant tumors, which could silence tumor suppressor gene via trimethylation of H3K27. Herein was first reported a novel series of pyrrole-3-carboxamide derivatives carrying with 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 of EZH2. DM-01 was found to have a significant ability to reduce cellular H3K27me3 level in K562 cells in Western blot test. Meanwhile, our data showed knockdown EZH2 in A549 cells resulted in the 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 downstream of EZH2, suggesting it was worthy to investigate further as a lead compound.
