| General tips | For obtaining a higher solubility , please warm the tube at 37 ℃ and shake it in the ultrasonic bath for a while.Stock solution can be stored below -20℃ for several months. We recommend that you prepare and use the solution on the same day. However, if the test schedule requires, the stock solutions can be prepared in advance, and the stock solution must be sealed and stored below -20℃. In general, the stock solution can be kept for several months. Before use, we recommend that you leave the vial at room temperature for at least an hour before opening it. |

Inhibition of protein kinase CKII activity by euchrestaflavanone B purified from Cudrania tricuspidata.[Pubmed:16408697]
Oncol Res. 2005;15(6):327-32.
The CKII (EC 2.7.1.37) inhibitory compound was purified from the root barks of Cudrania tricuspidata and identified as (2S)-2-[2,4-dihydroxy-5-(3-methyl-but-2-enyl)-phenyl]-5,7-dihyroxy-6-(3-methyl-bu t-2-enyl)chroman-4-one (Euchrestaflavanone B). Euchrestaflavanone B was shown to inhibit the phosphotransferase activity of CKII with IC50 of about 78 microM. Steady-state studies revealed that Euchrestaflavanone B acted as a competitive inhibitor with respect to the substrate ATP. A value of 16.4 microM was obtained for the apparent Ki. Concentration of 0.8 microM Euchrestaflavanone B caused 50% growth inhibition of human cancer cells U937 and HeLa. Euchrestaflavanone B-induced cell death was characterized with the cleavage of poly(ADP-ribose) polymerase and procaspase-3, indicating that the inhibitor triggered apoptosis. Because protein kinase CKII is involved in cell proliferation and oncogenesis, these results suggest that Euchrestaflavanone B may function by inhibiting oncogenic disease, at least in part, through the inhibition of CKII activity.
