Biological Activity
EMD638683 is an orally active and highly selective serum/glucocorticoid-regulated kinase 1 (SGK1) inhibitor (IC50 = 3 μM against HeLa cellular NDRG1 phosphorylation) th at significantly decreased blood pressure in fructose-treated mice but not in control saline-treated or in SGK1-knockout animals (4460 ppm in chow, ~600 mg/kg/day). EMD638683 promotes radiation-induced suicidal death of CaCo-2 colon tumor cells in vitro (50 μM) and decreases the number of colonic tumors following chemical carcinogenesis in vivo (4460 ppm in chow).
