  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.
