TEAD1 in complex with a reversible inhibitor N-[(1S)-2-hydroxy-1-(1-methyl-1H-pyrazol-3-yl)ethyl]-2-methyl-8-[4-(trifluoromethyl)phenyl]-2H,8H-pyrazolo[3,4-b]indole-5-carboxamide
Structural highlights
DiseaseTEAD1_HUMAN Defects in TEAD1 are the cause of Sveinsson chorioretinal atrophy (SCRA) [MIM:108985; also known as atrophia areata (AA) or helicoidal peripapillary chorioretinal degeneration (HPCD). SCRA is characterized by symmetrical lesions radiating from the optic disk involving the retina and the choroid.[1] [2] [3] FunctionTEAD1_HUMAN Transcription factor which plays a key role in the Hippo signaling pathway, a pathway involved in organ size control and tumor suppression by restricting proliferation and promoting apoptosis. 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 specifically and cooperatively to the SPH and GT-IIC 'enhansons' (5'-GTGGAATGT-3') and activates transcription in vivo in a cell-specific manner. The activation function appears to be mediated by a limiting cell-specific transcriptional intermediary factor (TIF). Involved in cardiac development. Binds to the M-CAT motif.[4] [5] Publication Abstract from PubMedTaking the structural information into account, we were able to tune the TEAD selectivity for a specific chemotype. However, different TEAD selectivity profiles did not affect the compound potency or efficacy in the NCI-H226 viability assay. Amides based on MSC-4106 or analogues showed improved viability efficacy compared with the corresponding acids. The amide M3686 exhibited AUC-driven efficacy in NCI-H226 xenograft models and had an improved 25-fold lower human dose prediction than MSC-4106. MSC-4106 was also used in HDX-MS studies to aid in the understanding of the MoA of P-site binding TEAD inhibitors. Artificial P-site binders rigidify certain areas in the periphery of the transcription factor that seem to be crucial for cofactor interaction, whereas a native fatty acid increased the protein dynamics of cofactor-binding interfaces.
