Aryl–indolyl maleimides as inhibitors of CaMKIIδ. Part 3: Importance of the indole orientation
摘要:
A family of aryl-substituted maleimides was prepared and studied for their activity against calmodulin dependant kinase. Inhibitory activities against the enzyme ranged from 10 nM to > 20 mu M and were dependant upon both the nature of the aryl group and the tether joining the basic amine to the indolyl maleimide core of the inhibitors. Key interactions with the kinase ATP site and hinge region, predicted by homology modeling, were confirmed. (C) 2008 Elsevier Ltd. All rights reserved.
