The core of this pathway is composed of a kinase cascade wherein MST1/MST2, in complex with its regulatory protein SAV1, phosphorylates and activates LATS1/2 in complex with its regulatory protein MOB1, which in turn phosphorylates and inactivates YAP1 oncoprotein and WWTR1/TAZ. Acts by mediating gene expression of YAP1 and WWTR1/TAZ, thereby regulating cell proliferation, migration and epithelial mesenchymal transition (EMT) induction. Binds to the SPH and GT-IIC 'enhansons' (5'-GTGGAATGT-3'). May be involved in the gene regulation of neural development. Binds to the M-CAT motif. Publication Abstract from PubMed Targeting the YAP1/TEAD interaction, a critical Hippo pathway signaling complex involved in transcriptional aberrations in cancer, represents a novel approach for treating Hippo-driven malignancies including mesothelioma. Our discovery campaign relied on virtual screening, X-ray crystallography and structure-activity relationship (SAR) studies were carried out to invent a novel aryl ether sulfonamide series with promising inhibitory activity. Leveraging synthetic modularity, we applied high-throughput experimentation for reaction optimization to enable key bond disconnections and SAR elucidation via library synthesis, followed by discrete FEP-guided designs, resulting in improved potency and pharmacokinetic profiles. These efforts identified MRK-A, a highly potent and selective lead compound with significantly improved cross-species pharmacokinetics and solubility compared to early leads. MRK-A demonstrated a robust PKPD relationship via selective, dose-dependent modulation of TEAD-driven genes and achieved complete tumor growth inhibition in the mesothelioma NCI-H226 xenograft mouse model with no observed adverse events.
