Medellin, Brenda;Yang, Wanjie;Konduri, Srihari;Dong, Jiajun;Irani, Seema;Wu, Haoyi;Matthews, Wendy L.;Zhang, Zhong-Yin;Siegel, Dionico;Zhang, Yan research published 《 Targeted Covalent Inhibition of Small CTD Phosphatase 1 to Promote the Degradation of the REST Transcription Factor in Human Cells》, the research content is summarized as follows. The repressor element-1 silencing transcription factor (REST) represses neuronal gene expression, whose dysregulation is implicated in brain tumors and neurol. diseases. A high level of REST protein drives the tumor growth in some glioblastoma cells. While transcription factors like REST are challenging targets for small-mol. inhibitors, the inactivation of a regulatory protein, small CTD phosphatase 1 (SCP1), promotes REST degradation and reduces transcriptional activity. This study rationally designed a series of α,β-unsaturated sulfones to serve as potent and selective covalent inhibitors against SCP1. The compounds inactivate SCP1 via covalent modification of Cys181 located at the active site entrance. Cellular studies showed that the inhibitors inactivate SCP1 in a time- and dose-dependent manner with an EC₅₀ ~1.5μM, reducing REST protein levels and activating specific REST-suppressed genes. These compounds represent a promising line of small-mol. inhibitors as a novel lead for glioblastoma whose growth is driven by REST transcription activity.
