In Vitro
In vitro	PF-477736 (128 nM) abrogates the camptothecin-induced DNA damage checkpoint in a dose-dependent manner in CA46 and HeLa cells. PF-477736 effectively abrogates the -induced S-phase arrest with a corresponding increase in apoptotic cell populations in HT29 cells. PF-477736 (540 nM) enhances -induced cytotoxicity in a time- and dose-dependent manner in HT29 cells. PF-477736 potentiates the growth-inhibitory activity of a panel of chemotherapeutic agents across a broad spectrum of p53-deficient human cancer cell lines in the MTT assay. Addition of PF-477736 (360 nM) to -arrested cells induces a dramatic increase in the intensity of H2AX phosphorylation, reflecting a greater number of γ-H2AX molecules near sites of DNA damage. ^[1] PF-477736 (0.5 nM) selectively blocks p73 and P53 phosphorylation in presence of curcumin in HL-60 cells. ^[2] PF-477736 (360 nM) suppresses -induced phosphorylation of histone H3 (Ser10) and Cdc25C (Ser216) and potentiates apoptosis in COLO205 cells. ^[3] PF-477736 (250 nM) combined with MK-1775 has marked synergistic cytotoxic activity in OVCAR-5 cells. PF-477736 (250 nM) combined with MK-1775 causes accumulation of cells with a DNA content between 2N and 4N in OVCAR-5 cells. PF-477736 (250 nM) combined with MK-1775 causes premature mitosis before the end of DNA replication, with damaged DNA leading to apoptotic cell death in OVCAR-5 cells. ^[4]
Kinase Assay	Binding assay
Kinase Assay	The assay is performed in a 96-well plate for 20 minutes at 30℃ in 0.1 mL of assay buffer containing 50 mM TRIS pH 7.5, 0.4 M NaCl, 4 mM PEP, 0.15 mM NADH, 28 units of lactate dehydrogenase/mL, 16 units of pyruvate kinase/mL, 3 mM DTT, 0.125 mM Syntide-2, 0.15 mM ATP and 25 mM magnesium chloride. Assays are initiated with 1 nM of CHK1 kinase domain. The inhibition of CHK1 activity is determined by measuring initial velocities in the presence of varying concentrations of PF-477736. The data is analyzed using Enzyme Kinetic and Excel software and fit to a kinetic model for competitive inhibition to obtain a Ki value. The kinase selectivity of PF-477736 is evaluated by screening the compound at 1 μM or 10 μM against a panel 2 of about 100 protein kinases.
細胞実験	細胞株	HT29, Colo205, PC-3, MDA-MB-231 and K562 cells
	濃度	~1 μM
	反応時間	96 hours
	実験の流れ	The IC50 assay measures the antiproliferative effects of PF-477736 on p53-defective human cancer cell lines. Cells in each line are seeded in complete medium at an exponentially growing density in 96-well assay plate and allowed to attach for 16 hours. Serial dilutions of PF-477736 are then done, and appropriate controls are added to each plate. Cells are incubated with drug for 96 hours. After incubation, MTT working stock diluted in complete medium is added to each well, and cells are incubated for 4 hours. After centrifugation and supernatant removal, DMSO is added to each well and plates are read on SpectraMax plate reader at 540 nm.

In Vivo
In Vivo	PF-477736 (4 mg/kg i.v.) results in terminal half-life (T1/2) of 2.9 hours, AUC of 5.72 μg×hr/mL and CLp of 11.8 mL/min/kg in rats. PF-477736 dose-dependently enhances the antitumor activity of a maximum tolerated dose in the Colo205 xenograft mouse model. PF-477736 (12 mg/kg) induces an increase in the phosphorylation of histone H3 (Ser10) and of phospho-histone H2AX in the Colo205 xenograft mouse model. ^[1] PF-477736 (15 mg/kg i.p.) enhances induced tumor growth inhibition and tumor growth delay in COLO205 and MDA-MB-231 xenograft models. ^[3] PF 477736 (10 mg/kg once daily i.p.) combined with MK-1775 (30 mg/kg twice a day oral) leads to greater tumor growth inhibition in mice bearing OVCAR-5 xenografts. ^[4]

よくある質問（FAQ）

質問1:
Can you advise the vehicle suggested for S2904: 2% DMSO/40% PEG 300 at 5mg/ml, is it a suspension or clear solution? I wanted to know how to dissolve this compound for an i.p. injection in mice

回答
S2904 can dissolve in 2% DMSO/40% PEG 300 at 5mg/ml as a clear solution. If you are going to use this kind of vehicle, please dissolve the compound in DMSO clearly first, then add PEG300, then water.
