生物活性

PROTAC FLT-3 degrader 4 is an orally active CRBN-based FLT3-PROTAC degrader that potently induces FLT3-ITD degradation through the ubiquitin-proteasome system. PROTAC FLT-3 degrader 4 shows highly selective to FLT3-ITD mutant acute myeloid leukemia (AML) cells. (Blue: CRBN ligand, Black: linker; Pink: FLT3 inhibitor)[1].

体外研究
(In Vitro)

PROTAC FLT-3 degrader 4 (compound A20) 对 MV4-11 和 MOLM-13 细胞具有抗增殖活性(IC50 分别为 39.9 nM 和 169.9 nM)[1].
PROTAC
FLT-3 degrader 4(0.25-100 nM;24 小时)显示 MV4-11 和 MOLM-13 细胞中 FLT3-ITD 蛋白水平大幅降低[1]
PROTAC FLT-3 degrader 4(20 nM;12 h)可抑制 MV4-11 和 MOLM-13 细胞中的 FLT3-ITD 磷酸化及其下游信号介质,包括 STAT5、S6K 和 ERK[1]
PROTAC FLT-3 degrader 4 (20 nM; 12 h) 剂量依赖性地诱导 G1 期周期停滞。PROTAC FLT-3 degrader 4 还可剂量依赖性地诱导 MV4-11 和 MOLM-13 细胞凋亡[1]

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
