Gene Information

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

In the central nervous system, members of the Src family of tyrosine kinases (SFKs) are widely expressed and are abundant in neurons. The purpose of this study is to examine whether glycogen synthase-3 (GSK-3) is involved in SFK inhibitor-induced apoptosis.

Although regeneration is widespread among metazoa, the molecular mechanisms have been studied in only a handful of taxa. Of these taxa, fewer still are amenable to studies of embryogenesis. Our understanding of the evolution of regeneration, and its relation to
