  Synthesis and Protein Kinase Inhibitory Activity of Balanol Analogues with Modified Benzophenone Subunits

  摘要：

  A series of analogues of the protein kinase C (PKC) inhibitory natural product balanol which bear modified benzophenone subunits are described. The analogues were designed with the goal of uncovering structure - activity features that could be used in the development of PKC inhibitors with a reduced polar character compared to balanol itself. The results of these studies suggest that most of the benzophenone features found in the natural product are important for obtaining potent PKC inhibitory compounds. However, several modifications were found to lead to selective inhibitors of the related enzyme protein kinase A (PKA), and several specific modifications to the polar structural elements of the benzophenone were found to provide potent PKC inhibitors. In particular, it was found that replacement of the benzophenone carboxylate with bioisosteric equivalents could lead to potent analogues. Further, a tolerance for lipophilic substituents on the terminal benzophenone ring was uncovered. These results are discussed in light of recently available structural information for PKA.

  Two Practical Syntheses of Sterically Congested Benzophenones

  摘要：

  Two efficient syntheses of the sterically congested tetraortho-substituted benzophenone portion of balanol 1 (a potent PKC inhibitor) in a protected form are described. Ortho lithiation reactions are employed for the preparation of the required 1,2,3-trisubstituted aryl aldehydes (11 and 26) and for their subsequent coupling reactions (with 6 and 23, respectively). The resulting carbinol intermediates [12, 27 and 35 (from cross coupling of 11 and 23)] were then manipulated to the corresponding benzophenonecarboxylic acids 2, 31, and 39, respectively. This chemistry is amenable to large scale synthesis, and multigram quantities of final products have been prepared.
