Biological activity
Description
Target:
eEF-2K:60 nM (IC50)
In Vivo
In Vitro
NH125 inhibits eEF-2 kinase activity (IC50 = 60 nM) in vitro, blocks the phosphorylation of eEF-2 in intact cells, and shows relative selectivity over other protein kinases: protein kinase C (IC50 = 7.5 μM), protein kinase A (IC50 = 80 μM), and calmodulin-dependent kinase II (IC50 > 100 μM). NH125 decreases the viability of 10 cancer cell lines with IC50s ranging from 0.7 to 4.7 μM. Forced overexpression of eEF-2 kinase in a glioma cell line produces 10-fold resistance to NH125. In conclusion, these results suggest that identification of potent inhibitors of eEF-2 kinase may lead to the development of new types of anticancer drugs[1]. Anticancer effect of NH125 is not mediated through inhibition of eEF2K. Inhibition of cell growth correlates with induction of peEF2[2].
