A patent review of EZH2 inhibitors from 2017 and beyond.

EZH2 is an important epigenetic regulator that forms the PRC2 complex with SUZ12, EED and RbAp46/48. As the key catalytic subunit of PRC2, EZH2 regulates the trimethylation of histone H3K27, which in turn promotes chromatin condensation and represses the transcription of relevant target genes. EZH2 overexpression and mutations are strictly related to tumor proliferation, invasion and metastasis. Currently, a large number of highly specific EZH2 inhibitors have been developed and some have already been in clinical trials. The aim of the present review is to provide an overview of the molecular mechanisms of EZH2 inhibitors and to highlight the research advances in the patent literature published from 2017 to date. A search of the literature and patents for EZH2 inhibitors and degraders was performed using the Web of Science, SCIFinder, WIPO, USPTO, EPO and CNIPA databases. In recent years, a great number of structurally diverse EZH2 inhibitors have been identified, including EZH2 reversible inhibitors, EZH2 irreversible inhibitors, EZH2-based dual inhibitors and EZH2 degraders. Despite the multiple challenges, EZH2 inhibitors offer promising potential for the treatment of various diseases, such as cancers.
