EMD638683 is a potent inhibitor of SGK1 with an IC50 value of 3 μM. EMD638683 treatment significantly augmented the radiation-induced decrease of forward scatter, increase of phosphatidylserine exposure, decrease of mitochondrial potential, increase of caspase 3 activity, increase of DNA fragmentation and increase of late apoptosis. EMD638683 promotes radiation-induced suicidal death of colon tumor cells in vitro and decreases the number of colonic tumors following chemical carcinogenesis in vivo.
