Transcriptional enhanced associate domain (TEAD) transcription factors undergo auto-palmitoylation, which is critical to mediate their function and maintain stability. Targeting the palmitate binding pocket of TEAD holds considerable promise for drug discovery, and it can be characterised into three components: a conserved cysteine, a hydrophobic main pocket, and a hydrophilic side pocket. Endogenous palmitate and several known TEAD inhibitors interact with the cysteine and hydrophobic residues in the deep hydrophobic pocket. We anticipate that precise targeting of the polar side pocket could facilitate the discovery of inhibitors with enhanced potencies and properties. Herein, we selected niflumic acid as the core scaffold suitable for targeting the three characteristic components of TEAD palmitate pocket. Reversible and irreversible compounds with substituents capable of directing each part of the palmitate pocket were designed. The newly synthesised compounds inhibited the palmitoylation and transcriptional activity of TEAD and elicited growth-inhibitory effects against several carcinomas, including mesothelioma.
