KT-333 ammonium
Based on 1 Customer Validation
KT-333 ammonium (Compound A) is a molecular glues that degrades STAT3 protein. KT-333 ammonium mediates the selective degradation of STAT3 through the ubiquitin-proteasome system by binding to STAT3 protein and E3 ubiquitin ligase von Hippel-Lindau protein (VHL). KT-333 ammonium has strong selectivity for STAT3 protein degradation and good antitumor activity. KT-333 ammonium can be used in the study of hematologic malignancies such as large granular lymphocytic leukemia (LGL-L), peripheral T-cell lymphoma (PTCL), and cutaneous T-cell lymphoma (CTCL).

Biological Activity
|
STAT3 |
KT-333 ammonium (11.8±2.3 nM, 48 h) degrades STAT3 resulted in irreversible growth inhibition of SU-DHL-1 cell line and induces caspase 3/7 activity in the SU-DHL-1 cell line[1].
KT-333 ammonium has a good degradation effect on STAT3 protein, and in cell phenotypic analysis, its GI50 value in multiple ALCL cell lines ranges from 8.1 to 57.4 nM[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
KT-333 ammonium (10, 20 and 30 mg/kg, iv.; once a week for two weeks) exhibits dose-dependent antitumor activity. Female NOD SCID mice with xenograft tumors of SUP-M2 administered with 10 mg/kg achieved 83.8% tumor growth inhibition (TGI), while those administered 20 or 30 mg/kg experienced complete tumor regression, with these effects sustained until the end of the study[1].
