  9-Cyano-1-azapaullone (Cazpaullone), a Glycogen Synthase Kinase-3 (GSK-3) Inhibitor Activating Pancreatic β Cell Protection and Replication

  摘要：

  Recently, the serine/threonine kinase glycogen synthase kinase-3 (GSK-3) emerged as a regulator of pancreatic beta cell growth and survival. On the basis of the previous observation that GSK-3 inhibitors like 1-azakenpaullone promote beta cell protection and replication, paullone derivatives were synthesized including 1-aza-, 2-aza-, and 12-oxapaullone scaffolds. In enzymatic assays distinct 1-azapaullones were found to exhibit selective GSK-3 inhibitory activity. Within the series of 1-azapaullones, three derivatives stimulated INS-1E beta cell replication and protected INS-1E cells against glucolipotoxicity induced cell death. Cazpaullone (9-cyano-1-azapaullone), the most active compound in the protection assays, also stimulated the replication of primary beta cells in isolated rat islets. Furthermore, cazpaullone showed a pronounced transient stimulation of the mRNA expression of the beta cell transcription factor Pax4, an important regulator of beta cell development and growth. These features distinguish cazpaullone as a unique starting point for the development of beta cell regenerative agents which might be useful in the treatment of diabetes.

  To develop multikinase inhibitors with dual PLK1/VEGF-R2 inhibitory activity, the d-annulated 1-benzazepin-2-one scaffold present in the paullone family of kinase inhibitors was investigated as a general structure template suitable for anchoring annulated heterocycles at the hinge region of the ATP binding site. For this purpose, the indole substructure of the paullones was replaced by other nitrogen containing heteroaromatics. The designed scaffolds were synthesized and tested on the indicated kinases. The 2-anilino-5.7-dihydro-6H-pyrimido[5,4-d][1]benzazepin-6-ones were found to be VEGF-R2 inhibitors with selectivity against the insulin receptor kinase. The attachment of a methoxy group to the 9-position of the scaffold led to additional PLK1 inhibitory activity, which was explained by an alternative binding mode of the 9-methoxy derivatives. Selected members of the compound class inhibited the VEGF-R2 autophosphorylation in human umbilical vein endothelial cells, the sprouting of human umbilical vein endothelial cell speroids, and the proliferation of diverse cancer cell lines.
