生物活性:
PD0166285 dihydrochloride, a substrate of P-gp, is a WEE1 inhibitor and a weak Myt1 inhibitor with IC50 values of 24 and 72 nM, respectively. PD0166285 dihydrochloride exhibits an IC50 of 3.433 μM for Chk1.

体内研究:
Animal Model:Wild-type, Abcg2-/-, Abcb1a/b-/- and Abcb1a/b;Abcg2-/- FVB mice.
Dosage:5 mg/kg.
Administration:IV.
Result:Cmax is about 400 ng/mL. P-gp, but not BCRP, limited the brain penetration of PD0166285.

体外研究:
PD0166285 (0.5 μM) dramatically inhibits irradiation-induced Cdc2 phosphorylation at the Tyr-15 and Thr-14 in seven of seven cancer cell lines.PD0166285 sensitizes radiation-induced cell killing in p53 mutant HT29 cells and in the E6-transfected, p53-null ovarian cancer cell line PA-1 but to a lesser extent in p53 wild-type PA-1 cells. PD0166285 abrogates irradiation-induced G2 arrest and significantly increases mitotic cell populations.PD0166285 acts as a radiosensitizer to sensitize cells to radiation-induced cell death with a sensitivity enhancement ratio of 1.23.
