UO-126

用途MAPキナーゼカスケード阻害剤。

説明U-0126 is a MEK inhibitor with IC50 values of 72 nM and 58 nM for MEK1 and MEK2, respectively. It is noncompetitive with respect adenosine triphosphate (ATP) and its phosphorylation target ERK and it shows little to no inhibition against a number of other kinases including PKC, Ab1, Raf, MEKK, ERK, JNK, MKK-3, MKK-4, MKK-6, Cdk2, and Cdk4. However, U-0126 does phosphorylate and activate AMP-activated protein kinase (AMPK) in a dose-dependent manner (EC50 = 15 μM in HEK293 cells). It increases the ratios of ADP to ATP and AMP to ATP and increases phosphorylation of the AMPK target acetyl-CoA carboxylase (ACC).

使用U0126 is a MEK inhibitor.

一般的な説明A potent and specific inhibitor of MEK1 (IC50 = 72 nM) and MEK2 (IC50 = 58 nM). The inhibition is noncompetitive with respect to MEK substrates, ATP and ERK. Has very little effect on other kinases, such as Abl, Cdk2, Cdk4, ERK, JNK, MEKK, MKK-3, MKK-4/SEK, MKK-6, PKC, and Raf. Shown to block doxazosin-induced osteoblastic differentiation. U0126 also acts as an immunosuppressant by effectively blocking IL-2 synthesis and T cell proliferation without affecting the long-term outcomes of either T cell activation or tolerance. Noncompetitive with respect to ATP. Also available in InSolution format (Cat. No. 662009.
