TEAD ligand-Linker Conjugate 3 (the blue structure + black structure of A536 in the literature) is a conjugate of a TEAD1-targeting ligand and a linker. TEAD ligand-Linker Conjugate 3 can be coupled with an IAP ligand (HY-181531) to form an IAP-recruiting bifunctional protein degrader (IPD) (HY-181594), also known as a SNIPER degrader. This TEAD SNIPER simultaneously binds to the TEAD1 palmitoylation pocket and the BIR3 domain of cIAP1 to form a ternary complex, efficiently inducing the ubiquitination and degradation of both TEAD1 and cIAP1 (DC₅₀=110 nM, D_max=51%; IC₅₀=122 nM for cIAP1).
