VT103

VT103, an analog of VT101, is an orally active and selective TEAD1 protein palmitoylation inhibitor. VT103 inhibits YAP/TAZ-TEAD promoted gene transcription, blocks TEAD auto-palmitoylation, and disrupts interaction between YAP/TAZ and TEAD . VT103 can be used for the research of cancer In Vitro VT103 (HEK293T cells; 3 μM) appeares to be TEAD1-selective, as it does not block palmitoylation of TEAD2, TEAD3, or TEAD4. VT103 (NF2-deficient NCI-H226 cells; 3 mmol/L; 4 or 24 hours) selectively disrupts YAP–TEAD1 interaction. VT103 results in the disappearance of palmitoylated TEAD1 with a concomitant increase in unpalmitoylated TEAD1. VT103 shows an IC 50 of 1.02 nM in YAP reporter assay.
