In the Hippo signaling pathway, the palmitoylated transcriptional enhanced associated domain (TEAD) protein interacts with the coactivator Yes-associated protein/PDZ-binding motif, leading to transcriptional upregulation of oncogenes such as Ctgf and Cyr61. Consequently, targeting the palmitoylation sites of TEAD has emerged as a promising strategy for treating TEAD-dependent cancers. Compound 1 was identified using a structure-based drug design approach, leveraging the molecular insights gained from the known TEAD palmitoylation site inhibitor, K-975. Optimization of the initial hit compound resulted in the development of compound 3, a covalent pan-TEAD inhibitor characterized by high potency and oral bioavailability.
