Olomoucine

Biochem/physiol Actions

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

Reversible: yes

Product competes with ATP.

Primary Targetp34^cdk1/cyclin B

Cell permeable: yes

General description

A purine derivative that acts as a potent, reversible and selective inhibitor of p34^cdk1/cyclin B (IC₅₀ = 7 µM) and related kinases including p33^cdk2/cyclin A (IC₅₀ = 7 µM), p33^cdk2/cyclin E (IC₅₀ = 7 µM), p33^cdk5/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, p34^cdk4/cyclin D (IC₅₀ >1 mM), and p40^cdk6/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 p34^cdc2/cyclin B (IC₅₀ = 7 µM) and related kinases, including p33^cdk2/cyclin A (IC₅₀ = 7 µM), p33^cdk2/cyclin E (IC₅₀ = 7 µM), p33^cdk5/p35 (IC₅₀ = 3 µM), and p44^MAPK (IC₅₀ = 25 µM). Acts by competing for the ATP binding domain of the kinase. Exhibits reduced sensitivity towards related kinases, p34^cdk4/cyclin D1 (IC₅₀ >1000 µM) and p40^cdk6/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.
