K-975 is a potent, selective and orally active TEAD inhibitor, with a strong inhibitory effect against protein-protein interactions between YAP1/TAZ and TEAD. K-975 covalently binds to Cys359 located in the palmitate-binding pocket of TEAD via an acrylamide structure. K-975 exhibits antitumor activity on malignant pleural mesothelioma[1].

K-975 (0.1-10000 nM; 144 h) inhibits the cell proliferation of NF2-non-expressing malignant pleural mesothelioma (MPM) cell lines[1].K-975 (10-10000 nM; 24 h) inhibits protein-protein interaction (PPI) between Halo-YAP and endogenous TEAD1/4 and Halo-TAZ and TEAD1/4 in NCI-H226 cells[1].K-975 (0.1-10000 nM; 24 h) strongly inhibits the reporter activity in NCI-H661/CTGF-Luc cells, with the maximum inhibition of ~70%, and does not inhibit the reporter activity in NCI-H661/NRF2-Luc cells[1].K-975 (1-10000 nM; 24 h) decreases the expressions of CTGF, IGFBP3, and NPPB mRNAs, and increases the expression of FBXO32 mRNA in NCI-H226 cells[1].

K-975 (10-300 mg/kg; p.o. twice a day for 14 days) inhibits the tumor growth by inhibiting YAP1/TAZ-TEAD signaling in MPM xenograft mouse models[1].
