H122
Based on 1 Customer Validation
H122 is a PROTAC degrader for TEAD that degrades TEAD1 with a DC50 of 3 nM. H122 exhibits good affinity to TEAD2, TEAD3, and TEAD4 with Ki values of 2.0, 3.6 and 1.6 nM, respectively. H122 relies on binding to TEAD1 and CRBN, functional E3 ligase activity, and a functional proteasome for degradation.H122 induces degradation of TEAD3 and forms a ternary complex with TEAD4 and CRBN/DDB1 to mediate degradation.H122 downregulates expression of Myc target genes. H122 exhibits antitumor efficacy in MSTO-211H mouse xenograft models.H122 can be used for the research of malignant mesothelioma.

Biological Activity
H122 (Compound 40) binds potently to human TEAD1, TEAD2, TEAD3, and TEAD4 proteins in vitro, with highest affinity for TEAD1 (Ki=0.3 nM)[1].
H122 promotes the formation of a ternary complex between TEAD4 and the CRBN/DDB1 E3 ligase complex in vitro, a key step for PROTAC-mediated degradation[1].
H122 (4 days) potently inhibits the growth of MSTO-211H and NCI-H226 cancer cell lines in vitro, with higher activity in NCI-H226 cells (IC50=0.6 nM)[1].
H122 (10-100 nM; 1-24 h) potently and rapidly degrades TEAD1, TEAD3, and TEAD4 proteins in MSTO-211H and NCI-H226 cancer cells, with TEAD1 degradation DC50=3.0 nM in MSTO-211H cells[1].
H122 (0.1-1000 nM; 4 h) suppresses the expression of TEAD target genes in MSTO-211H cells in vitro in a dose-dependent manner, confirming inhibition of TEAD transcriptional activity[1].
H122 (100 nM; 4 h) induces widespread transcriptional reprogramming in MSTO-211H cells, with significant downregulation of Myc target genes and other TEAD-associated oncogenic genes[1].
H122 (1-1000 nM; 24 h (cell cycle), 48 h (apoptosis)) induces G1 cell cycle arrest and apoptosis in MSTO-211H cancer cells, contributing to its antiproliferative activity[1].

Animal Model:BALB/c nude (female, 5-6 weeks old, MSTO-211H cell xenograft model)[1]
-
Dosage:10 mg/kg; 20 mg/kg; 50 mg/kg
-
Administration:i.p.; daily for 21 days (10, 20 mg/kg); single injection (50 mg/kg)
-
Result:Significantly reduced TEAD1 levels in MSTO-211H tumor tissues (TEAD3/4 degradation was less pronounced, TEAD2 was undetectable) with a single 50 mg/kg i.p.
dose.
Resulted in a tumor volume T/C value of 37.7% (markedly reduced tumor growth compared to control) with daily 20 mg/kg i.p.
treatment for 21 days.
Inhibited tumor growth, with less robust efficacy than the 20 mg/kg dose, with daily 10 mg/kg i.p.
treatment for 21 days.
Observed no loss of body weight in treated mice, indicating good tolerance.
Led to persistent reduction of TEAD1 levels in tumor tissues with prolonged 20 mg/kg treatment.
