Background on 1-Azakenpaullone

1-Azakenpaullone is a selective and cell-permeable inhibitor of glycogen synthase kinase-3β (GSK-3β) with IC50 value of 18nM [1, 2].

1-Azakenpaullone is a kenpaullone derivative with a modified heterocyclic basic structure. It shows potent inhibitory activity against GSK-3β over CDK1/cyclin B and CDK5/p25. The IC50 values for CDK1/cyclin B, CDK5/p25 and GSK-3β are 2μM, 4.2μM and 18nM, respectively. As an inhibitor of GSK-3β, 1-Azakenpaullone is developed as potential antidiabetic drug. 1-Azakenpaullone is found to protect rat insulinoma cell line INS-1E cells from glucolipotoxicity and stimulate cell proliferation. Besides that, 1-Azakenpaullone promotes the replication of beta cells in isolated rat islets at concentration of 1μM. In addition, 1-Azakenpaullone is reported to have effect in changing cardiac myocyte morphology. It increases cell area primarily through the elongation of the cells [1, 2 and 3].

1-Azakenpaullone is a selective inhibitor of glycogen synthase kinase-3 beta.[Pubmed: 14698171]

Kenpaullone derivatives with a modified parent ring system were synthesized in order to develop kinase inhibitors with enhanced selectivity. Among the novel structures, 1-azakenpaullone was found to act as a selective GSK-3beta versus CDK1 inhibitor. The charge distribution within the 1-azakenpaullone molecule is discussed as a possible explanation for the enhanced GSK-3beta selectivity of 1-azakenpaullone compared to other paullone derivatives.
