目录号 : GC72852Helenalin acetate是一种天然的NF-κB抑制剂,是一种有效的C/EBPβ抑制剂。
Cas No.:10180-86-6
Sample solution is provided at 25 µL, 10mM.
Helenalin acetate, a natural NF-κB inhibitor, is a potent C/EBPβ inhibitor. Helenalin acetate has anti-inflammatory and anticancer activities.
Helenalin acetate (0.1-1 μM; for 7 days) inhibits the differentiation significantly in 3T3-L1 cells[1].Helenalin acetate exerts anti-proliferative effects in acute myeloid leukemia cells but not in normal hematopoietic progenitor cells[1]. Helenalin acetate inhibits C/EBPβ by binding to the N-terminal part of C/EBPβ, thereby disrupting the cooperation of C/EBPβ with the co-activator p300. Helenalin acetate selectively inhibits only the full-length (liver-enriched activating protein* (LAP*)) isoform but not the slightly shorter (LAP) isoform[1].

工作液浓度: mg/ml;
DMSO母液配制方法: mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL,
体内配方配制方法:取 μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL saline,混匀澄清。
1. 首先保证母液是澄清的;
2.
一定要按照顺序依次将溶剂加入,进行下一步操作之前必须保证上一步操作得到的是澄清的溶液,可采用涡旋、超声或水浴加热等物理方法助溶。
3. 以上所有助溶剂都可在 GlpBio 网站选购。
