Discovery of Clinical Candidate IAG933, a Potent YAP-TEAD PPI Disrupter

The interaction of transcriptional enhanced associate domain (TEAD) and transcriptional coactivator yes-associated protein (YAP) mediates oncogenic functions downstream of the Hippo pathway. In this report, we outline our efforts to find a potent inhibitor of this protein–protein interaction with suitable properties for clinical evaluation. We detail the medicinal chemistry program that led to the discovery of IAG933, an inhibitor with a balanced ADME profile, enabling its evaluation as a potential treatment option in clinical settings.
