  Conformationally Constrained Analogues of Diacylglycerol. 26. Exploring the Chemical Space Surrounding the C1 Domain of Protein Kinase C with DAG-Lactones Containing Aryl Groups at the sn-1 and sn-2 Positions

  摘要：

  Diacylglycerol lactones (DAG-lactones) are known to operate as effective agonists of protein kinase C (PKC), surpassing in potency the activity of natural diacylglycerol (DAG). Localization of activated PKC isozymes in the cell is determined in part by the different cellular scaffolds, the lipid composition of the specific membranes, and the targeting information intrinsic to the individual isoforms bound to DAG. This multifaceted control of diversity suggests that, to develop effective DAG-lactones capable of honing in on a specific cellular target, we need to gain a better understanding of the chemical space surrounding its binding site. Seeking to augment the chemical repertoire of DAG-lactone side chains that could steer the translocation of PKC to specific cellular domains, we report herein the effects of incorporating simple or substituted phenyl residues. A combined series of n-alkyl and phenyl substitutions were used to explore the optimal location of the phenyl group on the side chains. The substantial differences in binding affinity between DAG-lactones with identical functionalized phenyl groups at either the sn-1 or sn-2 position are consistent with the proposed binding model in which the DAG-lactone binds to the C1 domain of PKC with the acyl chain oriented toward the interior of the membrane and the alpha-alkylidene or alpha-arylalkylidene chains directed to the surface of the C1 domain adjacent to the lipid interface. We conclude that DAG-lactones containing alpha-phenylalkylidene side chains at the sn-2 position represent excellent scaffolds upon which to explore further chemical diversity.
