Description General description A purine derivative that acts as a potent, reversible and selective inhibitor of p34cdk1/cyclin B (IC50 = 7 µM) and related kinases including p33cdk2/cyclin A (IC50 = 7 µM), p33cdk2/cyclin E (IC50 = 7 µM), p33cdk5/p35 (IC50 = 3 µM), and p44 MAP kinase (IC50 = 25 µM). Acts by competing for the ATP binding domain of the kinase. Exhibits reduced sensitivity towards related kinases, p34cdk4/cyclin D (IC50 > 1 mM), and p40cdk6/cyclin D3 (IC50 > 250 µM). Does not significantly affect the activity of other protein kinases at 1 mM. Known to inhibit DNA synthesis in interleukin-2-stimulated T lymphocytes and trigger G1 arrest similar to that observed in interleukin-2-deprived cells. Also used to synchronize cells in G1. A 50 mM (5 mg/336 µl) solution of Olomoucine (Cat. No. 495624) in DMSOis also available. A purine derivative that acts as a potent, reversible, and selective inhibitor of p34cdc2/cyclin B (IC50 = 7 µM) and related kinases, including p33cdk2/cyclin A (IC50 = 7 µM), p33cdk2/cyclin E (IC50 = 7 µM), p33cdk5/p35 (IC50 = 3 µM), and p44MAPK (IC50 = 25 µM). Acts by competing for the ATP binding domain of the kinase. Exhibits reduced sensitivity towards related kinases, p34cdk4/cyclin D1 (IC50 > 1000 µM) and p40cdk6/cyclin D3 (IC50 > 250 µM). Does not significantly affect the activity of other protein kinases even at 1 mM concentrations. Known to inhibit DNA synthesis in interleukin-2 stimulated T lymphocytes and triggers G1 arrest similar to that observed in interleukin-2 deprived cells. Also used to synchronize cells in G1. Packaging 1, 5 mg in Plastic ampoule Biochem/physiol Actions Cell permeable: yes Primary Target p34cdk1/cyclin B Product competes with ATP. Reversible: yes Target IC50: 7 µM, 7 µM, 7 µM, 3 µM, 25 µM against p34cdk1/cyclin B, p33cdk2/cyclin A, p33cdk2/cyclin E, p33cdk5/p35, and p44 MAP kinase, respectively Warning Toxicity: Standard Handling (A) Reconstitution Following reconstitution, aliquot and freeze (-20°C). DMSO stock solutions are stable for up to 6 months at -20°C. Other Notes Abraham, R.T., et al. 1995. Biol. Cell 83, 105. Mistelli, T., and Warren, G. 1995. J. Cell Sci. 108, 2715.
