产品描述

SC-514是一种口服有效的，ATP竞争性的IKK-2抑制剂，IC50为3-12 μM，抑制NF-κB依赖性的基因表达，不抑制其他IKK异构体或其他丝-苏氨酸和酪氨酸激酶。

靶点（IC50 & Targe）

Aurora B,71μM

CDK2/CyclinA,61μM

IKK2,3μM-12μM

p38α,>100μM

PRAK,75μM

体外研究

SC-514以相似的强度抑制天然的IKK复合物或重组人IKK-1/IKK-2异二聚体和IKK-2同源二聚体的活性。在的IL-1β诱导的类风湿性关节炎的滑膜成纤维细胞（RASFs）中，SC-514抑制NF-κB依赖性的IL-6，IL-8，COX-2基因表达，IC50分别为20 μM，20 μM和8 μM。在RASFs中，100μM的SC-514抑制IκBα的磷酸化和降解，也降低p65转移到细胞核中的量。

体内研究

在急性模型中，SC-514有效抑制LPS诱导的血清TNF-α生成。SC-514（50毫克/公斤，腹腔注射）抑制达70%TNF-α生产。[1]

产品说明

一般描述

A cell-permeable (thienothienyl)amino-acetamide compound that displays anti-inflammatory properties. Acts as a potent, reversible, ATP-competitive, and highly selective inhibitor of IKK-2 (IC₅₀ = ~ 3-12 µM for IKK-2 homodimer, IKK-1/IKK-2 heterodimer, and IKK-2). Its specificity has been confirmed using a panel of 31 other kinases, including IKK isoforms IKK-1, IKK-i, and TBK-1 (IC₅₀ >200 µM). Shown to specifically block NF-κB-dependent gene expression, but not MAP kinase pathways, in stimulated synovial fibroblasts RASF. A 25 mM (1 mg/178 µl) solution of IKK-2 Inhibitor, SC-514 (Cat. No. 401485) in DMSO is also available.
A cell-permeable, potent, reversible, ATP-competitive and highly selective inhibitor of IKK-2 (IC₅₀ ~3-12 µM for IKK-2 homodimer, IKK-1/IKK-2 heterodimer, and IKK-2) that also displays anti-inflammatory properties. Specificity has been reported using a panel of 31 additional kinases, including IKK isoforms IKK-1, IKK-i, and TBK-1 (IC₅₀ >200 µM). Shown to specifically block NF-κB-dependent gene expression, but not MAP kinase pathways, in stimulated RASF synovial fibroblast cells. Does not inhibit the phosphorylation and activation of the IKK complex.

应用

SC-514 has been used to study its effect on lipopolysaccharide (LPS)-induced phosphorylation of NF-κB (nuclear factor-κB) p65 and p38 MAPK (mitogen-activated protein kinase).

生化/生理作用

SC-514 is a cell-permeable, potent and selective ATP competitive inhibitor of nuclear factor kappa-B kinase-2 (IKK-2) that specifically blocks NF-?B-dependent gene expression. SC-514 exhibits anti-inflammatory properties.
SC-514 is an amino-acetamide compound. It is selective for IKKβ with an IC50 value of 3−12 μM. SC-514 also inhibits cytokines such as interleukin-6 (IL-6) and IL-8, mediated by IKKβ. IKKβ is responsible for osteoclast survival, hence its inhibition affects osteogenesis.
