实验参考方法
In Vitro

In vitro activity: PD0166285 is identified to inhibit Wee1 activity at nanomolar concentrations. The inhibitor abrogates G2/M checkpoint inducing early cell division. At the cellular level, 0.5 μM PD0166285 dramatically inhibits irradiation-induced Cdc2 phosphorylation at the Tyr-15 and Thr-14 in seven of seven cancer cell lines tested. This G2 checkpoint abrogation by PD0166285 is demonstrated to kill cancer cells. PD0166285 does not inhibit Cdc2/cyclin B but inhibits Chk1 kinase at a much higher concentration (3433 nM). the treatment of cells with the inhibitor is related to microtubule stabilization and decrease in cyclin D transcription. Thus, PD0166285 may be a potentially useful anti-cancer therapy.


Kinase Assay: Wee1 mass screening is performed using Amersham’s p34cdc2 kinase SPA kit with some modifications. Briefly, 45–60 nM full-length Wee1 kinase is incubated with 25 μM compounds, 20 μM ATP, and 122–441 nM Cdc2/cyclin B in a final volume of 50 μl of enzyme dilution buffer [50 mM Tris (pH 8.0), 10 mM NaCl, 10 mM MgCl2, 1 mM DTT, and 0.1 mM Na3VO4]. After 30 min incubation at 30°C, 30 μl of [33P]ATP containing kinase buffer [67 mM Tris (pH 8.0), 40 mM NaCl, 13 mM MgCl2, 1 mM DTT, and 0.13 mM Na3VO4] containing 1 μM biotinylated peptide, and 0.25 μCi of [γ-33P]ATP is added to the reaction and incubated for another 30 min at 30°C. The reaction is stopped by adding 200 μl of stop buffer [50 μM ATP, 5 mM EDTA, 0.1% Triton X-100, and 1.25 mg/ml SPA beads in PBS]. After centrifugation at 2400 rpm for 15 min, the plate is counted with Wallac’s Microbeta counter.


Cell Assay: B16 cells (1 × 105 cells in 100 mm-dishes) are maintained in medium overnight. In addition, the cells are treated with (0, 0.5, 1.0, or 2.0 μM) PD0166285 (including DMSO vehicle) for indicated times. The cells are washed twice with phosphate-buffered saline (PBS). Next, the cells are trypsinized, so the cell numbers in each dish are determined by using a computed cell-counter (Sysmex CDA-500) according to manufacturer's recommendation.

In VivoPD0166285 at 0.5 μM concentration can inhibit Cdc2Y15 /T14 phosphorylation in all cell lines tested, regardless of their p53 status and pharmacological targeting of WEE1 by PD0166285 sensitizes U251-FM GBM tumors to IR in vivo.
