Application

Alsterpaullone has been used to stabilize β-catenin.
Alsterpaullone inhibits GSK-3β, CDK5/p25, and CDK1/cyclin B. Alsterpaullone has also been studied as an antimanic therapeutic for the acute manic phase of bipolar disorder.

Biochem/physiol Actions

Alsterpaullone (ALP) is a cyclin-dependent kinase (CDK) inhibitor. It is considered as a therapeutic agent for group 3 medulloblastomas. Alsterpaullone modulates the progression of cell cycle. It can arrest cell cycle and stimulate the apoptosis of cancer cells by activating caspase-9 through perturbation of mitochondrial membrane potential.
Potent and selective inhibitor of GSK-3β and CDK5/p25; potent inhibitor of CDK1/cyclin B (IC50 = 0.035 μM).

The paullones represent a novel class of small molecule cyclin-dependent kinase (CDK) inhibitors. To investigate structure-activity relationships and to develop paullones with antitumor activity, derivatives of the lead structure kenpaullone (9-bromo-7,12-dihydroindolo[3,2-d][1]benzazepin-6(5H)-one, 4a) were synthesized. Paullones with different substituents in the
