U0126 109511-58-2 CAS NO.109511-58-2

U0126 is a highly selective inhibitor of both MEK1 and MEK2, a type of MAPK/ERK kinase. U0126 was found to functionally antagonize AP-1 transcriptional activity via noncompetitive inhibition of the dual specificity kinase MEK with IC50 of 72 nM for MEK1 and 58 nM for MEK2. U0126 inhibited anchorage-independent growth of Ki-ras-transformed rat fibroblasts by simultaneously blocking both extracellular signal-regulated kinase (ERK) and mammalian target of rapamycin (mTOR)-p70(S6K) pathways. The effects of U0126 on the growth of eight human breast cancer cell lines shown that U0126 selectively repressed anchorage-independent growth of MDA-MB231 and HBC4 cells, two lines with constitutively activated ERK. Loss of contact with substratum triggers apoptosis in many normal cell types, a phenomenon termed anoikis. U0126 sensitized MDA-MB231 and HBC4 to anoikis, i.e., upon treatment with U0126, cells deprived of anchorage entered apoptosis.

U0126 is also a weak inhibitor of PKC, Raf, ERK, JNK, MEKK, MKK-3, MKK-4/SEK, MKK-6, Cdk2 and Cdk4.

1. By "the suggested storage temperature is at -20℃", we mean you should keep the left compound at -20℃ after you open the vial and could not use the compound out at one time.
2. Most of our compounds are in dry powder and of very good stability, so it is safe during the transition at room temperature and it could last for 1-2 weeks and even more.
3. For some specific sensitive compounds, we will ship them with dry ice or blue ice.
