MUS81 Inhibitors

MUS81 inhibitors constitute a diverse group of compounds that either directly target MUS81 or indirectly modulate its activity by affecting key cellular pathways involved in DNA repair and genomic stability. Triapine, a small molecule inhibitor of ribonucleotide reductase, indirectly influences MUS81 by disrupting DNA synthesis and repair processes. Triapine-induced ribonucleotide reduction inhibition leads to altered DNA structures and replication stress, affecting MUS81-mediated resolution of DNA structures. Mirin, an MRE11 inhibitor, indirectly modulates MUS81 activity by interfering with the MRE11-mediated DNA repair pathway. By inhibiting MRE11, Mirin disrupts the processing of DNA structures and impairs the normal function of MUS81 in DNA repair and maintenance.

NSC 19630, an inhibitor of Bloom helicase (BLM), indirectly affects MUS81 by disrupting the BLM-mediated resolution of DNA structures. NSC 19630-induced BLM inhibition leads to altered DNA repair processes, impacting MUS81's role in resolving DNA intermediates and contributing to genomic stability. Camptothecin, a topoisomerase I inhibitor, indirectly affects MUS81 by disrupting DNA topological changes. Camptothecin-induced topoisomerase I inhibition leads to altered DNA structures, affecting MUS81-mediated resolution of DNA intermediates and impairing its role in DNA repair processes. ATR inhibitor (AZD6738), an inhibitor of the ataxia-telangiectasia and Rad3-related (ATR) kinase, indirectly modulates MUS81 by disrupting ATR-mediated DNA damage response pathways. ATR inhibitor-induced ATR inhibition leads to altered DNA repair processes, affecting MUS81-mediated resolution of DNA structures and contributing to genomic stability. A-196, a selective inhibitor of EZH2, indirectly influences MUS81 by targeting the EZH2-mediated epigenetic regulation of gene expression. A-196-induced EZH2 inhibition leads to altered gene expression patterns, affecting pathways involved in DNA repair and modulating MUS81-mediated resolution of DNA structures.
