SGK1 inhibitor is an inhibitor of serum- and glucocorticoid-regulated kinase 1 (SGK1) and SGK2 (IC50s = 4.8 and 2.8 nM, respectively). It is selective for SGK1 and SGK2 over SGK3 in the presence of a high concentration of ATP (IC50s = 0.442, 0.924, and 23.3 μM, respectively) and only inhibits AMPK by more than 50% in a panel of 60 additional kinases when used at a concentration of 1 μM. SGK1 inhibitor prevents phosphorylation of GSK3β in U2OS cells with an IC50 value of 1.4 μM. It decreases cell viability in BYL719-insensitive HCC1954 cells when used in combination with the PI3Kα inhibitor BYL719 . SGK1 inhibitor (50 mg/kg) reduces tumor growth in an HCC1954 mouse xenograft model when administered in combination with BYL719.

Discovery of Herbacetin as a Novel SGK1 Inhibitor to Alleviate Myocardial Hypertrophy
Adv Sci (Weinh) 2022 Jan;9(2):e2101485.PMID:34761560DOI:10.1002/advs.202101485.
Cardiac hypertrophy is a pivotal pathophysiological step of various cardiovascular diseases, which eventually leads to heart failure and death. Extracts of Rhodiola species (Ext.R), a class of commonly used medicinal herbs in Europe and East Asia, can attenuate cardiac hypertrophy both in vitro and in vivo. Serum/glucocorticoid regulated kinase 1 (SGK1) is identified as a potential target of Ext. R. By mass spectrometry-based kinase inhibitory assay, herbacetin (HBT) from Ext.R is identified as a novel SGK1 Inhibitor with IC50 of 752 nmol. Thermal shift assay, KINOMEscan in vitro assay combined with molecular docking proves a direct binding between HBT and SGK1. Site-specific mutation of Asp177 in SGK1 completely ablates the inhibitory activity of HBT. The presence of ?OH groups at the C-3, C-8, C-4' positions of flavonoids is suggested to be favorable for the inhibition of SGK1 activity. Finally, HBT significantly suppresses cardiomyocyte hypertrophy in vitro and in vivo, reduces reactive oxygen species (ROS) synthesis and calcium accumulation. HBT decreases phosphorylation of SGK1 and regulates its downstream forkhead box protein O1 (FoxO1) signaling pathway. Taken together, the findings suggest that a panel of flavonoids structurally related to HBT may be novel leads for developing new therapeutics against cardiac hypertrophy.
Unlocking SGK1 Inhibitor potential of bis-[1-N,7-N, pyrazolo tetraethoxyphthalimido{-4-(3,5-Dimethyl-4-(spiro-3-methylpyazolo)-1,7-dihydro-1H-dipyrazolo[3,4-b;4',3'-e]pyridin-8-yl)}]p-disubstituted phenyl compounds: a computational study
J Biomol Struct Dyn 2022;40(24):13412-13431.PMID:34696688DOI:10.1080/07391102.2021.1988711.
SGK1 (Serum and Glucocorticoid Regulated Kinase 1), a serine/threonine kinase that is activated by various stimuli, including serum and glucocorticoids. It controls inflammation, apoptosis, hormone release, neuro-excitability and cell proliferation, all of which play an important role in cancer progression and metastasis. SGK1 was recently proposed as a potential drug target for cancer, diabetes, and neurodegenerative diseases. In this study, molecular docking, physiochemical, toxicological properties and molecular dynamic simulation of the Bis-[1-N,7-N, Pyrazolo tetraethoxyphthalimido{-4-(3,5-Dimethyl-4-(spiro-3-methylpyazolo)-1,7-dihydro-1H-dipyrazolo[3,4-b;4',3'-e]pyridin-8-yl)}]p-disubstituted phenyl compoundsand reference EMD638683 against new SGK1 target protein. Compared to the reference inhibitor EMD638683, we choose the best compounds (series 2-6) based on the binding energy (in the range from -11.0 to -10.6 kcal/mol). With the exception of compounds 2 and 6, none of the compounds posed a risk for AMES toxicity or carcinogenicity due to their toxicological properties. 100 ns MD simulation accompanied by MM/PBSA energy calculations and PCA. According to MD simulation results, the binding of compounds 3, 4 and 5 stabilizes the SGK1 structure and causes febrile conformational changes compared to EMD638683. As a result of this research, the final selected compounds 3, 4 and 5 can be used as scaffolds to develop promising SGK1 inhibitors for the treatment of related diseases such as cancer.Communicated by Ramaswamy H.

SGK1 Inhibitor reverses hyperglycemia partly through decreasing glucose absorption
J Mol Endocrinol 2016 May;56(4):301-9.PMID:27287220DOI:10.1530/JME-15-0285.
This study investigates the effectiveness and mechanisms of a serum- and glucocorticoid-inducible kinase 1 (SGK1) inhibitor in counteracting hyperglycemia. In an in vivo experiment, we demonstrated that after an 8-week treatment with an SGK1 Inhibitor, the fasting blood glucose and HbA1c level significantly decreased in db/db mice. RT-PCR and western blot analyses revealed that intestinal SGK1 and sodium glucose co-transporter 1 (SGLT1) expression were enhanced in db/db mice. Treatment with an SGK1 Inhibitor decreased excessive SGLT1 expression in the intestine of db/db mice. In vitro experiments with intestinal IEC-6 cells showed that the co-administration of an SGK1 Inhibitor partly reversed the SGLT1 expression and glucose absorption that were induced by dexamethasone. In conclusion, this study revealed that the favorable effect of an SGK1 Inhibitor on hyperglycemia is partly due to decreased glucose absorption through SGLT1 in the small intestine. These data collectively suggest that SGK1 may be a potent target for the treatment of diabetes and other metabolic disorders.
SGK1-Sensitive Regulation of Cyclin-Dependent Kinase Inhibitor 1B (p27) in Cardiomyocyte Hypertrophy
Cell Physiol Biochem 2015;37(2):603-14.PMID:26344141DOI:10.1159/000430380.
Background/aims: The serum- and glucocorticoid-inducible kinase SGK1 participates in the orchestration of cardiac hypertrophy and remodeling. Signaling linking SGK1 activity to cardiac remodeling is, however, incompletely understood. SGK1 phosphorylation targets include cyclin-dependent kinase inhibitor 1B (p27), a protein which suppresses cardiac hypertrophy. The present study explored how effects of SGK1 on nuclear p27 localization might modulate the hypertrophic response in cardiomyocytes. Methods: Experiments were performed in HL-1 cardiomyocytes and in SGK1-deficient (sgk1-/-) and corresponding wild-type (sgk1+/+) mice following pressure overload by transverse aortic constriction (TAC). Transcript levels were quantified by RT-PCR, protein abundance by Western blotting and protein localization by confocal microscopy. Results: In HL-1 cardiomyocytes, overexpression of constitutively active SGK1 (SGK1S422D) but not of inactive SGK1 (SGK1K127N) increased significantly the cell size and transcript levels encoding Acta1, a molecular marker of hypertrophy. Those effects were paralleled by almost complete relocation of p27 in the cytoplasm. Treatment of HL-1 cardiomyocytes with isoproterenol was followed by up-regulation of SGK1 expression. Moreover, isoproterenol treatment stimulated the hypertrophic response and was followed by disappearance of p27 from the nuclei, effects prevented by the SGK1 Inhibitor EMD638683. The effect of SGK1S422D overexpression on Acta1 mRNA levels was disrupted by overexpression of p27 and of the p27T197A mutant lacking the SGK1 phosphorylation site, but not of the phosphomimetic p27T197D mutant. In sgk1+/+ mice, TAC increased significantly SGK1 and Acta1 mRNA levels and decreased the nuclear to cytoplasmic protein ratio of p27 in cardiac tissue, effects blunted in the sgk1-/- mice. Conclusion: SGK1-induced hypertrophy of cardiomyocytes involves p27 phosphorylation at T197, which fosters cytoplasmic p27 localization.
The SGK1 Inhibitor EMD638683, prevents Angiotensin II-induced cardiac inflammation and fibrosis by blocking NLRP3 inflammasome activation
Biochim Biophys Acta Mol Basis Dis 2018 Jan;1864(1):1-10.PMID:28986310DOI:10.1016/j.bbadis.2017.10.001.
Inflammation has emerged as a critical biological process contributing to hypertensive cardiac remodeling. Effective pharmacological treatments targeting the cardiac inflammatory response, however, are still lacking. Prior studies suggested that the serum- and glucocorticoid-inducible kinase (SGK1) plays a key role in inflammation and cardiac remodeling. Recently, a highly selective SGK1 Inhibitor, EMD638683, was developed, though whether EMD638683 can prevent hypertension-induced cardiac fibrosis and the mechanisms by which this inhibitor may alter the disease process remain unknown. Using a murine Angiotension II (Ang II) infusion-induced hypertension model we found that EMD638683 treatment inhibited cardiac fibrosis and remodeling, with significant abatement of cardiac inflammation. EMD638683 was shown to suppress Ang II infusion-induced interleukin (IL)-1β release, and substantially reduce nucleotide-binding oligomerization domain-like receptor with pyrin domain 3 (NLRP3) expression and caspase-1 activation in cardiac tissues. In vitro experiments revealed that EMD638683 ameliorated Ang II-stimulated IL-1β secretion in macrophages by blocking NLRP3 inflammasome activation. By reducing IL-1β production in macrophages, the transformation of fibroblasts to myofibroblasts was inhibited. The effects of EMD638683 on cardiac fibrosis were abolished by supplementation with exogenous IL-1β. Administration of the NLRP3 inflammasome inhibitor MCC950 indicated that EMD638683 attenuated Ang II-induced cardiac inflammation and fibrosis by inhibiting the NLRP3 inflammasome/IL-1β secretion axis. These findings indicate that the SGK1 Inhibitor EMD638683 can negatively regulate NLRP3 inflammasome activation, and may represent a promising approach to the treatment of hypertensive cardiac damage.
