EMD638683 is an orally active SGK1 inhibitor with an IC50 of 3 µM. EMD638683 exhibits strong inhibition against SGK1, moderate inhibition against SGK2 and SGK3, and shows excellent selectivity for other AGC kinase family members. EMD638683 has antihypertensive activity by inhibiting SGK1, and independently of the blood pressure-lowering effect, it effectively prevents heart inflammation and fibrosis caused by hypertension by inhibiting the cardiac NLRP3 inflammation body/ IL-1beta axis. EMD638683 promotes apoptosis of colon cancer cells and sensitizes radiotherapy. EMD638683 (S-Form) can be used in research related to hypertension, hypertensive heart damage, and colon cancer[1][2][3].
