9-Cyano-1-azapaullone (Cazpaullone), a Glycogen Synthase Kinase-3 (GSK-3) inhibitor activating pancreatic β cell protection and replication
Recently, the serine/threonine kinase glycogen synthase kinase-3 (GSK-3) emerged as a regulator of pancreatic β cell growth and survival. On the basis of the previous observation that GSK-3 inhibitors like 1-azakenpaullone promote β cell protection and re
1-Azakenpaullone is a selective inhibitor of glycogen synthase kinase-3β
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-3β versus CDK1 inhibitor. The charge distribution within the 1-azakenpaullone molecule is discussed as a possible explanation for the enhanced GSK-3β selectivity of 1-azakenpaullone compared to other paullone derivatives.
