製品説明

Roscovitine is a potent and selective CDK inhibitor for Cdc2, CDK2 and CDK5 with IC50 of 0.65 μM, 0.7 μM and 0.16 μM in cell-free assays. It shows little effect on CDK4/6. Phase 2.

Targets

CDK5/p35 ^[1] (Cell-free assay)	Cdc2/CyclinB ^[1] (Cell-free assay)	CDK2/CyclinA ^[1] (Cell-free assay)	CDK2/CyclinE ^[1] (Cell-free assay)	ERK2 ^[1] (Cell-free assay)
0.16 μM	0.65 μM	0.7 μM	0.7 μM	14 μM

In Vitro
In vitro	Roscovitine displays high efficiency and high selectivity towards some cyclin-dependent kinases with IC50 of 0.65, 0.7, 0.7 and 0.16 μM for cdc2/cyclin B, cdk2/cyclin A, cdk2/cyclin E and cdk5/p53, respectively. ^[1] Roscovitine reversibly inhibits the prophaselmetaphase transition in the micromolar range of starfish oocytes and sea urchin embryos, inhibits in vitro M-phase-promoting factor activity and in vitro DNA synthesis in Xenopus egg extracts, and suppresses the proliferation of mammalian cell lines with an average IC50 of 16 μM. ^[1] In mesangial cells, Roscovitine results in a dose-dependent reduction of CDK2 activity that at concentrations of 7.5, 12.5 and 25 mM, Roscovitine causes a 25, 50% and 100% decrease in CDK2 activity, respectively. ^[2] A recent study shows that Roscovitine inhibits cdk5 kinase activity, cell proliferation, multicellular development, and cdk5 nuclear translocation in Dictyostelium discoideum, without affecting the expression of cdk5 protein during axenic growth. ^[3]
Kinase Assay	Enzymes
Kinase Assay	Kinases activities are assayed at 30 °C in buffer C. Blank values are subtracted from the data and activities calculated as molar amount of phosphate incorporated in protein acceptor during a 10-minute incubation. Controls are performed with appropriate dilutions of DMSO. In a few cases, phosphorylation of the substrate is assessed by autoradiography after SDS/PAGE. p34^cdc2/cyclin B is purified from M-phase starfish (M. glacialis) oocytes by affinity chromatography. It is assayed with 1 mg histone Hl/mL, in the presence of 15 μM [γ-³²P]ATP (3000 Ci/mmol; 1 mCi/mL) in a final volume of 30 μL. After a 10-minute incubation at 30 °C, 25-μL aliquots of supernatant are spotted onto pieces of Whatman P81 phosphocellulose paper, and, after 20 seconds, the filters are washed five times (for at least 5 minutes each time) in a solution of 10mL phosphoric acid/L water. The wet filters are transferred into 6-mL plastic scintillation vials, 5 mL ACS scintillation fluid is added and the radioactivity measured in a Packard counter. The kinase activity is expressed as molar amount of phosphate incorporated in histone H1 during a 10-minutes incubation or as a percentage of maximal activity. p33^cdk2/cyclin A and p33^cdk2/cyclinE are reconstituted from extracts of sf9 insect cells infected with various baculoviruses. Cyclins A and E are fusion proteins with glutathione S-transferase and the complexes are purified on glutathione-agarose beads. Kinase activities are assayed with 1 mg/mL histone H1, in the presence of 15 μM [γ-³²P]ATP, during 10 minutes, in a final volume of 30 μL, as described for the p34^cdc2/cyclin B kinase. p33^cdk5/p35 is purified from bovine brain, excluding the Mono S-chromatographic step. The active fractions from the Superose 12 column are pooled and concentrated to a final concentration of approximately 25 μg enzyme/mL. The kinase is assayed with 1 mg/mL histone HI in the presence of 15 μM [γ-³²P]ATP, during 10 minutes in a final volume of 30 μL, as described for the p34^cdc2/cyclin B kinase. p33^cdk5/cyclin D1 is obtained from insect cell lysates. Cdk4 is a fusion protein with glutathione-S-transferase and the active complex is purified on glutathione-agarose beads. Its kinase activity is assayed with purified retinoblastoma protein (complexed with glutathione-S-transferase) in the presence of 15 μM [γ-³²P]ATP, in a final volume of 30 μL. After a 15-minute incubation, 30 μL Laemmli sample buffer is added. The phosphorylated substrate is resolved by 10 % SDS/PAGE and analysed by autoradiography by overnight exposure to Hyperfilm MP and densitometry. p33^cdk4/cyclinD 2 is obtained from insect cell lysates. It is assayed with purified retinoblastoma protein (complexed with glutathione-S-transferase) in the presence of 15 μM [γ-³²P]ATP in a final volume of 30 μL. After a 30-minute incubation, 30 μL Laemmli sample buffer is added. The phosphorylated substrate is resolved by 10% SDS/PAGE and analysed by autoradiography by overnight exposure to Hyperfilm MP and densitometry. MAP kinase erkl (tagged with glutathione-S-transferase), is expressed in bacteria, purified on glutathione-agarose beads and assayed with 1 mg myelin basic protein/ml in the presence of 15 μM [γ-³²P]ATP as described above for the p34^cdc2cyclin B kinase. His-tagged erkl and erk2 are activated in vitro by mitogen-activated protein kinase kinase, purified (Ni-affinity and Mono Q) and assayed as described above during 10 minutes in a final volume of 30 μL. The catalytic subunit of cAMP-dependent protein kinase, purified from bovine heart, is assayed with 1 mg histone Hl/ml, in the presence of 15 μM [γ-³²P]ATP as described for the p34^cdc2/cyclin B kinase. cGMP-dependent protein kinase, purified to homogeneity from bovine tracheal smooth muscle, is assayed with 1 mg histone Hl/mL, in the presence of 15 μM [γ-³²P]ATP as described for the p34^cdc2/cyclin B kinase. Casein kinase 2 is isolated from rat liver cytosol and assayed with 1 mg casein/mL and 15 μM [γ-³²P]ATP. The substrate is spotted on Whatmann 3MM filters and washed with 10% (mass/vol.) trichloroacetic acid. Myosin light chain kinase, purified from chicken gizzard is assayed in the presence of 100 nM calmodulin, 100 μM CaCl₂, 50 mM Hepes, 5 mM MgCI,, 1 mM dithiothreitol and 0.1 mg BSA/ml at pH 7.5 using a synthetic peptide based on the smooth-muscle myosin light-chain phosphorylation site and in the presence of 15 μM [γ-³²P]ATP, in a final volume of 50 μL. Incorporation of radioactive phosphate is monitored on phosphocellulose filters as described above. ASK-γ, a plant homologue of GSK-3, is expressed as a glutathione-S-transferase fusion protein in Escherichia coli and purified on glutathione-agarose. ASK-γ kinase is assayed, for 10 minutes at 30 °C, with 5 μg myelin basic protein, in the presence of 15 μM [γ-³²P]ATP in a final volume of 30 μL. The phosphorylated myelin basic protein is recovered on Whatman P81 phosphocellulose paper as described for the p34^cdc2/cyclin B kinase. Insulin receptor tyrosine kinase domain (CIRK-41) is overexpressed in a baculovirus system and purified to homogeneity. Its kinase activity is assayed, for 10 minutes at 30 °C, with 5 μg Raytide, in the presence of 15 μM [γ-³²P]ATP, in a final volume of 30 μL. The phosphorylated Raytide is recovered on Whatman P81 phosphocellulose paper as described for the p34^cdc2/cyclin B kinase. c-src kinase is purified from infected Sf9 cells. The v-abl kinase is expressed in E. coli and affinity purified on IgG Affigel 10. Both kinases are assayed for 10 minutes at 30 °C, with 5 μg Raytide, in the presence of 15 μM [γ-³²P]ATP, in a final volume of 30 μL. The phosphorylated Raytide is recovered on Whatman P81 phosphocellulose paper as described for the p34^cdc2/cyclin B kinase.

よくある質問（FAQ）

質問1:
How can I reconstitute the drug for in vivo studies?

回答
S1153 in 1% DMSO+10% Tween 80+20% N-N-dimethylacetamide+PEG 400 is a clear solution which is okay for injection. And S1153 in 1% DMSO+30% polyethylene glycol+1% Tween 80 at 30mg/ml is a suspension, which is fine for oral gavage.
