IC50: 24 nM (WEE1), 72 nM (Myt1), 3.433 μM (Chk1)[1]. |
| In Vitro | PD0166285 (0.5 μM) dramatically inhibits irradiation-induced Cdc2 phosphorylation at the Tyr-15 and Thr-14 in seven of seven cancer cell lines[1]. 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[1]. PD0166285 acts as a radiosensitizer to sensitize cells to radiation-induced cell death with a sensitivity enhancement ratio of 1.23[1]. Western Blot Analysis[1] Cell Line: Human and mouse cancer cell lines (HCT116, HT29, DLD-1, HCT8, H460, HeLa, C 26). Concentration: 0.5 μM. Incubation Time: 4 h. Result: Inhibited Cdc2Y15 and CdcT14 phosphorylation. |
| In Vivo | Animal Model: Wild-type, Abcg2-/-, Abcb1a/b-/- and Abcb1a/b;Abcg2-/- FVB mice[2]. Dosage: 5 mg/kg. Administration: IV. Result: Cmax is about 400 ng/mL. P-gp, but not BCRP, limited the brain penetration of PD0166285. |
