生物活性

CRBN ligand-898 is a CRBN ligand with a Kd of 216 nM. CRBN ligand-898 binds to CRBN, and when incorporated into proteolysis targeting chimeras (PROTACs), mediates degradation of intended target proteins. CRBN ligand-898 does not induce degradation of IMiD-associated neosubstrates Ikaros (IKZF1) and Aiolos (IKZF3). CRBN ligand-898 can be used to synthesize PROTACs[1].

体外研究
(In Vitro)

CRBN ligand-898 (Compound 2) 与 CRBN 结合的 IC50 为 183 nM,Kd 为 216 nM[1]
CRBN ligand-898 不会抑制 hERG、NaV1.5、Kv4.3 离子通道 (IC50 >40 μM) 及 CaV 离子通道 (IC50 >100 μM),且不会在 THP-1 细胞中诱导细胞毒性 (IC50 >250 μM)[1]
CRBN ligand-898 (1-10 μM; 24 h) 在人白血病细胞 NB-4 中不会降解 Ikaros 或 Aiolos[1]
CRBN ligand-898 (0.0001-30 μM; 6 h) 可剂量依赖性地抑制 HiBiT-IKZF3 MM.1S 细胞中 IMiD 和 PROTAC 诱导的 Aiolos 降解,证实其可与 CRBN 结合且具有细胞通透性[1]
CRBN ligand-898 (1 μM; 24 h) 在 NB-4 人白血病细胞中以 1 μM 处理 24 小时后,不会降低任何蛋白质的水平,包括 IMiD 新底物[1]

Western Blot Analysis[1]

Cell Line: NB-4 human leukaemia cells
Concentration: 1, 10 μM

体内研究
(In Vivo)

CRBN ligand-898 (Compound 2) (10-100 mg/kg;口服;单次给药) 在 CrbnI391V 基因敲入小鼠中,会产生剂量依赖性的血浆暴露,且不会诱导脾脏组织中免疫调节类药物 (IMiD) 新底物 Ikaros 或 Aiolos 的降解[1]

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: CrbnI391V knock C57BL/6N (wild-type)[1]
Dosage: 10 mg/kg; 30 mg/kg; 100 mg/kg

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.
