6、 AKT 抑制劑，對 AKT1 和 AKT2 的 IC50 值分別為8.4 和 8.9 M；Oridonin 具有抗腫瘤、抗菌、抗炎等功效。IC & Target Akt1 Akt28.4 M (IC50) 8.9 M (IC50)體外研究 Oridonin is an ATP-competitive inhibitor of AKT with IC50s of 8.4 and 8.9 M for AKT1 and AKT2, respectively.Oridonin (5, 10 or 20 M) obviously inhibits the growth of KYSE70, KYSE4

7、10 and KYSE450 ESCC cells via targetingAKT1/2. Oridonin (10 or 20 M) causes G2/M phase cell cycle arrest in KYSE70, KYSE410 and KYSE450 cells, andinduces apoptosis in these three cell lines at 20 M. In addition, Oridonin (5, 10 or 20 M) in combination withcisplatin or 5-FU enhances the inhibition of

8、 esophageal squamous cell carcinoma (ESCC) cell growth1. Oridonin (0.1and 1 M) preferentially suppresses AKT/mTOR signaling. Oridonin (1 M) also selectively suppresses growth ofbreast cancer cells with hyperactivation of AKT signaling2.體內(nèi)研究 Oridonin (160 mg/kg, p.o.) shows significant reduction in t

9、he tumor growth without obvious weigh loss in SCID mice bearing EG9 and HEG18 tumor cells. Oridonin treatment also suppresses the expression of Ki-67, phosphorylated AKT, GSK-3 or mTOR in mice1.

10、de mice2.PROTOCOLKinase Assay 1 For the AKT kinase assay, the ADP-Glo Kinase Assay Kit is used. Active AKT1 or AKT2 kinase and inactive GSK-3 assubstrate are mixed by 1 reaction buffer and then added to a white 96-well plate. Pure ATP provided in the kit isserially diluted obtain a final concentrati

The mixed solution is incubated at roomtemperature and luciferase activity is measured using the Luminoskan Ascent plate reader1.MCE has not independently confirmed the ac

They are for reference only.Cell Assay 1 Cells are seeded (6103 cells/well for KYSE70; 2.5103 cells/well for KYSE410; 2103 cells/well for KYSE450) in 96-well plates and incubated for 24 h and then treated with different amounts of Oridonin or vehicle. After incubationfor 24,

13、 48 or 72 h, cell proliferation is measured by the MTT assay. For anchorage-independent cell growthassessment, cells (2.5, 5 or 10 M Oridonin) suspended in complete medium are added to 0.3% agar with vehicle,2.5, 5 or 10 M Oridonin in a top layer over a base layer of 0.5% agar with vehicle, 2.5, 5 o

Upon harvesting, tumors are fixed in formalinovernight and then in 70% ethanol for histopathology analysis. Mice are treated with Oridonin (15 mg/kg) in 1%Pluronic F68
