TEAD Degrader

PROTAC TEAD degrader-1 is a TEAD2 degrader and antiproliferative agent with selective activity toward TEAD2 relative to other TEAD family members. PROTAC TEAD degrader-1 relies on CRBN and the proteasome system for TEAD2 degradation; disruption of CRBN binding attenuates this activity. PROTAC TEAD degrader-1 decreases expression of YAP target genes CYR61 and CTGF. PROTAC TEAD degrader-1 can be used for the research of NF2-deficient cancer.

KG-FP-003 is a highly potent, selective, and durable TEAD PROTAC degrader (TEAD1 DC₅₀ = 6 ± 4 nM, TEAD2 DC₅₀ = 68 ± 15 nM, TEAD3 DC₅₀ = 12 ± 5 nM, TEAD4 DC₅₀ = 7 ± 5 nM). KG-FP-003 promotes ubiquitination and degradation of TEAD. KG-FP-003 exhibits anticancer activity against mesothelioma and ovarian cancer.

TEAD ligand 4 is a TEAD PROTAC ligand. TEAD ligand 4 can be conjugated with E3 ligase Ligand (HY-181591) and linker to synthesize PROTAC TEAD1/IAP degrader (HY-181590) .

PROTAC TEAD1/IAP degrader-1 (Compound A232) is a selective TEAD1 and cIAP1 PROTAC degrader, with DC₅₀ values of 14 nM and 270 nM, respectively. PROTAC TEAD1/IAP degrader-1 promotes the ubiquitination and degradation of TEAD1 and cIAP1. PROTAC TEAD1/IAP degrader-1 downregulates the expression of the TEAD-dependent gene CTGF. PROTAC TEAD1/IAP degrader-1 exhibits anticancer activity against mesothelioma.

PROTAC TEAD1/IAP degrader-3 is a TEAD1/IAP PROTAC degrader. PROTAC TEAD1/IAP degrader-3 recruits the cIAP1 and XIAP E3 ligases to form a ternary complex, drives proteasomal degradation of TEAD1, and triggers autoubiquitination and proteasomal degradation of cIAP1. PROTAC TEAD1/IAP degrader-3 inhibits cell proliferation. PROTAC TEAD1/IAP degrader-3 regulates Hippo pathway activity by downregulating CTGF gene expression in a TEAD-dependent manner. PROTAC TEAD1/IAP degrader-3 is applicable to the research of mesothelioma.

TEAD degrader-1 is a potent FBXO22-mediated molecular glue degrader of TEAD, with a 24 h DC₅₀ of 1.0 nM. TEAD degrader-1 binds reversibly and covalently to FBXO22 C326, assembles a functional ternary complex, and mediates proteasomal degradation of TEAD. TEAD degrader-1 exhibits high selectivity for the Hippo pathway and specifically downregulates only TEAD and its downstream target proteins. TEAD degrader-1 is applicable to research related to malignant pleural mesothelioma and non-small cell lung cancer.

PROTAC TEAD degrader-3 is a TEAD PROTAC degrader with an IC₅₀ of < 5 nM against TEAD1, TEAD2, TEAD3 and TEAD4. PROTAC TEAD degrader-3 promotes ubiquitination and degradation of TEAD1/2/3/4. PROTAC TEAD degrader-3 can be used in cancer research.

PROTAC TEAD degrader-2 (Compound 31) is an efficient TEAD1 PROTAC degrader with a DC₅₀ of 0.6 nM. PROTAC TEAD degrader-2 inhibits the YAP/TAZ-TEAD interaction, with a IC₅₀ of 1.8 nM. PROTAC TEAD degrader-2 exhibits significant selective inhibitory activity against YAP-dependent cancer cells and effectively suppresses the transcriptional activity mediated by YAP. PROTAC TEAD degrader-2 can be used for research on mesothelioma and glioma.

PROTAC TEAD/IAP degrader-1 is a TEAD/IAP PROTAC degrader. PROTAC TEAD/IAP degrader-1 is also a specific and Nongenetic inhibitor of apoptosis protein (IAP)-dependent protein eraser (SNIPERs). PROTAC TEAD/IAP degrader-1 recruits cIAP1 to form ternary complexes, induces ubiquitination, proteasomal TEAD1, TEAD4 degradation. PROTAC TEAD/IAP degrader-1 inhibits TEAD transcriptional activity, reduces CTGF expression, and reduces cell proliferation. PROTAC TEAD/IAP degrader-1 can be used for the research of mesothelioma.

PROTAC TEAD1/IAP degrader-2 is an IAP-harnessing TEAD1 PROTAC degrader, with a DC₅₀ of 170 nM against TEAD1 in NCI-H2052 cells. PROTAC TEAD1/IAP degrader-2 exhibits moderate antiproliferative activity in Hippo pathway-dependent mesothelioma cells. PROTAC TEAD1/IAP degrader-2 inhibits the expression of CTGF, but with a weaker effect than the TEAD inhibitor VT-107 (HY-134957). PROTAC TEAD1/IAP degrader-2 can be used in mesothelioma-related research.

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). TEAD ligand-Linker Conjugate 3 and its synthesized SENIPER molecule can be utilized in research on Hippo pathway dysregulation-related diseases, such as NF2-mutant tumors.
