1Discovery of a subtype-selective, covalent inhibitor against palmitoylation pocket of TEAD3显示文摘The TEA domain(TEAD)family proteins(TEAD1-4)are essential transcription factors that control cell differentiation and organ size in the Hippo pathway.Although the sequences and structures of TEAD family proteins are highly conserved,each TEAD isoform has unique physiological and pathological functions.Therefore,the development and discovery of subtype selective inhibitors for TEAD protein will provide important chemical probes for the TEAD-related function studies in development and diseases.Here,we identified a novel TEAD 1/3 covalent inhibitor(DC-TEADin1072)with biochemical IC50 values of 0.61±0.02 and 0.58±0.12μmol/L against TEAD1 and TEAD3,respectively.Further chemical optimization based on DC-TEAD in 1072 yielded a selective TEAD3 inhibitor DCTEAD3 in03 with the IC_(50) value of 0.16±0.03μmol/L,which shows 100-fold selectivity over other TEAD isoforms in activity-based protein profiling(ABPP)assays.In cells,DC-TEAD3 in03 showed selective inhibitory effect on TEAD3 in GAL4-TEAD(1-4)reporter assays with the IC50 value of1.15μmol/L.When administered to zebrafish juveniles,experiments showed that DC-TEAD3 in03 reduced the growth rate of zebrafish caudal fins,indicating the importance of TEAD3 activity in controlling proportional growth of vertebrate appendages.Tian Lu Yong Li Wenchao Lu TWGM Spitters Xueyu Fang Jun Wang Simian Cai Jing Gao Yanting Zhou Zhe Duan Huan Xiong Liping Liu Qi Li Hualiang Jiang Kaixian Chen Hu Zhou Hua Lin Huijin Feng Bing Zhou Christopher L.Antos Cheng Luo 2021Acta Pharmaceutica Sinica B2021,11,10:0
