≥5mg/ml

Taking the 1 mL working solution as an example, add 5 mg of this product to 1 ml of CMC-Na solution, mix evenly to obtain a homogeneous suspension with a final concentration of 5 mg/ml.

* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

生物活性

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.
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] This compound 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, it results in a dose-dependent reduction of CDK2 activity that at concentrations of 7.5, 12.5 and 25 mM, this chemical causes a 25, 50% and 100% decrease in CDK2 activity, respectively. ^[2] A recent study shows that this compound 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]
in vivo	Roscovitine, at a dose of 50 mg/kg, significantly inhibits growth of The Ewing's sarcoma family of tumors (ESFT) xenografts. ^[4] This compound enhances the antitumor effect of doxorubicin without increased toxicity with a mechanism that involves cell cycle arrest rather than apoptosis in nude mice bearing established MCF7 xenografts. ^[5]
