Staurosporine is a potent inhibitor of p34cdc2 and p34cdc2-like kinases
1992
Abstract We previously demonstrated that nontransformed cells arrest in the G1 phase of the cell cycle when treated with low concentrations (21 nM) of staurosporine (1). Both normal and transformed cells are blocked in the G2 phase of the cell cycle when treated with higher concentrations (160 nM) of staurosporine (1,2). In the present study, we show that staurosporine inhibits the activity of fractionated p34 cdc2 and p34 cdc2 -like kinases with IC50 values of 4–5 nM. We propose that the G2 phase arrest in the cell cycle caused by staurosporine is due, at least in part, to the inhibition of the p34 cdc2 kinases.
