GSK 650394 is a small molecule inhibitor of serum and glucocorticoid-regulated kinase 1 (SGK1) with IC50 value of 13nM [1].
Sgk1 gene is a target gene of androgen. Knockdown of SGK1 expression attenuates androgen-mediated growth of the prostate cancer cell line. Thus, the inhibition of SGK1 is a novel mechanism for the treatment of prostate cancer. GSK 650394 is a competitive inhibitor of SGK1. It shows potent inhibitory activity against the purified SGK1 with IC50 value of 13nM in a fluorescence polarization assay. In the activity-based scintillation proximity assay, GSK 650394 prevents the phosphorylation activity of SGK1 and SGK2 with IC50 values of 62nM and 103nM, respectively. Moreover, GSK 650394 suppresses the androgen-mediated increase of Nedd4-2 phosphorylation in LNCaP cells. It also significantly inhibits cell growth stimulated by androgen with IC50 value of about 1μM [1].

Scintillation proximity assay (SPA) |
SGK1 S422D (60-431 aa; 0.275 μg/mL final concentration) or SGK2 (0.875 μg/mL final concentration) were activated by PDK1 (1.1 μg/mL final concentration) in a buffer consisting of 50 mM Tris (pH 7.5), 0.1 mM EGTA, 0.1 mM EDTA, 10 mM MgCl2, 0.1% β-mercaptoethanol, 1 mg/mL BSA, and ATP (final concentration of 0.15 mM) and incubated for 30 mins at 30 °C. SGK2 was prepared exactly as described for SGK1, except it corresponded to the full-length protein. A solution containing biotinylated CROSStide peptide at a final concentration of 75 μM and γ32P-ATP corresponding to 2 × 106 cpm was prepared in the reaction buffer. In a 96-well plate, 5 μL of GSK 650394 was added to 25 μL of the activated enzyme mixture. To this, 20 μL of the CROSStide mixture was added and incubated for 1 hr at room temperature. Next, 50 μL of a 25 mg/mL slurry of streptavidin-coated SPA beads in PBS with 0.1 M EDTA, pH 8.0 was added. The plate was then sealed and centrifuged for 8 mins at 2000 rpm, and the signal was detected by measuring for 30 sec/well in a Packard TopCount NXT Scintillation Counter. The IC50 values of the inhibition of SGK1 and SGK2 activities by GSK 650394 were calculated from these data using GraphPad Prism 3 Software. |
