Abstract

Genetic mutations in components of the Hippo pathway frequently lead to the aberrant activation of TEADs, which is often associated with Cancer. Consequently, TEADs have been actively pursued as therapeutic targets for diseases driven by TEAD overactivation. In this study, we report two series of TEAD PROTACs based on CRBN Binders and VHL Binders. Both series yielded potent TEAD degraders, including 19 and 40 (H122), which induced TEAD1 degradation with DC50 < 10 nM. Mechanistic studies demonstrated that the degradation of TEAD1 induced by 40 relied on CRBN binding, TEAD1 binding, E3 Ligase activity, and a functional Proteasome. RNA-seq analyses indicated that 40 significantly downregulated the expression of Myc target genes, as highlighted by GSEA analysis. More importantly, 40 exhibited robust antitumor efficacy in the MSTO-211H mouse xenograft model. Collectively, our results suggest that TEAD PROTACs have therapeutic potential for the treatment of cancers associated with TEAD overactivation.
