BN82002 is a synthetic inhibitor of CDC25 phophatases, with IC50s of 2.4-6.3 μM for recombinant CDC25 phosphatases.
The effect of BN82002 on cell proliferation is evaluated in vitro on several human tumor cell lines. Menadione, which has been reported to inhibit cell proliferation, is used as a control. All of the examined cell lines are sensitive to BN82002 and Menadione in a concentration-dependent manner in the low micromolar range. The most sensitive is the pancreatic cancer cell line MIA PaCa-2 with an IC50 of 7.2 μM, and the less sensitive cell line is the colon cancer HT-29 with an IC50 of 32.6 μM. The range of activity is very similar to the one observed with menadione (5-15 μM). It is also showed that 50 μM BN82002 is a concentration that fully inhibits cell proliferation, the cell cycle distribution is only modestly affected with a slight decrease in S phase and an increase in cells containing both a G1 and a G2 DNA content, suggesting that the cells treated with BN82002 are arrested at various stages of the cell cycle[1].
