KT-333 是同类首创、强效且选择性的异双功能STAT3降解剂,可募集VHL E3连接酶进行泛素-蛋白酶体介导的降解。它在ALK⁺间变性大细胞淋巴瘤 (ALCL) 的临床前模型中诱导出强大的抗肿瘤活性。
KT-333 ammonium is a molecular glue that degrades STAT3 protein. KT-333 ammonium binds to STAT3 protein and the E3 ubiquitin ligase von Hippel-Lindau protein (VHL), utilizing the ubiquitin-proteasome system to mediate the selective degradation of STAT3. KT-333 ammonium exhibits strong selectivity for the degradation of STAT3 protein and good anti-tumor activity. KT-333 ammonium can be used in the research of hematological malignancies such as large granular lymphocyte leukemia (LGL-L), peripheral T-cell lymphoma (PTCL), and cutaneous T-cell lymphoma (CTCL).
| 动物 A (mg/kg) = 动物 B (mg/kg)×动物 B的Km系数/动物 A的Km系数 | |
例如,已知某工具药用于小鼠的剂量为88 mg/kg , 则用于大鼠的剂量换算方法:将88 mg/kg 乘以小鼠的Km系数(3),再除以大鼠的Km系数(6),得到该药物用于大鼠的等效剂量44 mg/kg。
