Bioactivity | KT-333 is a molecular glues that degrades STAT3 protein. KT-333 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 has strong selectivity for STAT3 protein degradation and good antitumor activity. KT-333 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)[1]. |
Invitro | KT-333 (11.8±2.3 nM,48 h) 对 STAT3 降解后使得 SU-DHL-1 细胞系产生了不可逆的生长抑制并诱导了半胱天冬酶 3/7 的活性,这是细胞凋亡的标志[1]。KT-333 显示出了对 STAT3 蛋白的降解作用,并且在细胞表型分析中,对多个 ALCL 细胞系的 GI50 值范围为 8.1 到 57.4 nM[1]。 MCE has not independently confirmed the accuracy of these methods.

In Vivo | KT-333 ammonium (5,10,15 和 45 mg/kg,iv.;一周一次持续两周) 显示出剂量依赖性的抗肿瘤活性。以 5 mg/kg 给药的小鼠实现了 79.9% 的肿瘤生长抑制 (TGI),而以10,15 或 45 mg/kg 给药的小鼠实现了完全的肿瘤消退,这些效果一直持续到研究结束[1]。KT-333 ammonium (10,20 和 30 mg/kg,iv.;一周一次持续两周) 显示出剂量依赖性的抗肿瘤活性。以 10 mg/kg 给药的小鼠实现了 83.8% 的肿瘤生长抑制 (TGI),而以 20 或 30 mg/kg 给药的小鼠实现了完全的肿瘤消退,这些效果一直持续到研究结束[1]。 MCE has not independently confirmed the accuracy of these methods.
