Alsterpaullone Chemical Properties,Usage,Production

Description

Alsterpaullone (237430-03-4) is a potent and selective inhibitor of GSK-3β and CDK5/p25. Potent inhibitor of CDK1/cyclin B (IC50 = 35 nM).1?Alsterpaullone induces apoptosis2 and inhibits angiogenesis3.

Uses

Alsterpaullone is a derivative of kenpaullone , an ATP-competitive inhibitor of several cyclin-dependent kinases (CDKs) as well as glycogen synthase kinase 3β (GSK3β). With slightly improved potency over kenpaullone, alsterpaullone selectively inhibits Cdk1/cyclin B, Cdk2/cyclin A, Cdk2/cyclin E, Cdk5/p25, and GSK3α/β with IC50 values of 35, 15, 200, 40, and 4 nM, respectively. Alsterpaullone has been used to inhibit the cytosolic degradation of β-catenin to alter the canonical Wnt signaling pathway in primary axis patterning, to reduce tau phosphorylation in an effort to modify neuropathological events associated with Alzheimer’s disease, and to alter cell proliferation or protein expression in various diseases.

Uses

Alsterpaullone has been used to stabilize β-catenin.

Uses

Alsterpaullone is a potent glycogen synthase kinase-3 inhibitor and a potential therapeutic agents for treatment of Parkinson disease.

Definition

ChEBI: Alsterpaullone is an organic heterotetracyclic compound that is 1,3-dihydro-2H-1-benzazepin-2-one which shares its 4-5 bond with the 3-2 bond of 5-nitro-1H-indole. It has a role as an EC 2.7.11.22 (cyclin-dependent kinase) inhibitor, an EC 2.7.11.1 (non-specific serine/threonine protein kinase) inhibitor, an EC 2.7.11.26 (tau-protein kinase) inhibitor, an antineoplastic agent, an apoptosis inducer and an anti-HIV-1 agent. It is a C-nitro compound, an organic heterotetracyclic compound and a member of caprolactams. It derives from a paullone.

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.
