  Conformationally Constrained Analogues of Diacylglycerol (DAG). 25. Exploration of the sn-1 and sn-2 Carbonyl Functionality Reveals the Essential Role of the sn-1 Carbonyl at the Lipid Interface in the Binding of DAG-Lactones to Protein Kinase C

  摘要：

  Diacylglycerol (DAG) lactones with altered functionality (C=O -> CH2 or C=O -> C=S) at the sn-1 and sn-2 carbonyl pharmacophores were synthesized and used as probes to dissect the individual role of each carbonyl in the binding to protein kinase C (PKC). The results suggest that the hydrated sn-1 carbonyl is engaged in very strong hydrogen-bonding interactions with the charged lipid headgroups and organized water molecules at the lipid interface. Conversely, the sn-2 carbonyl has a more modest contribution to the binding process as a result of its involvement with the receptor (Cl domain) via conventional hydrogen bonding to the protein. The parent DAG-lactones, E-6 and Z-7, were designed to bind exclusively in the sn-2 binding mode to ensure the correct orientation and disposition of pharmacophores at the binding site.

  Branched Diacylglycerol-Lactones as Potent Protein Kinase C Ligands and α-Secretase Activators

  摘要：

  Using as our lead structure a potent PKC ligand (1) that we had previously described, we investigated a series of branched DAG-lactones to optimize the scaffold for PKC binding affinity and reduced lipophilicity, and we examined the potential utility of select compounds as alpha-secretase activators. Activation of alpha-secretase upon PKC stimulation by ligands causes increased degradation of the amyloid precursor protein (APP), resulting in enhanced secretion of sAPP alpha and reduced deposition of beta-amyloid peptide (A beta), which is implicated in the pathogenesis of Alzheimer's disease. We modified in a systematic manner the C-5-acyl group, the 3-alkylidene, and the lactone ring in I and established structure-activity relationships for this series of potent PKC ligands. Select DAG-lactones with high binding affinities for PKC were evaluated for their abilities to lead to increased sAPP alpha secretion as a result of alpha-secretase activation. The DAG-lactones potently induced alpha-secretase activation, and their potencies correlated with the corresponding PKC binding affinities and lipophilicities. Further investigation indicated that 2 exhibited a modestly higher level of sAPP alpha secretion than did phorbol 12,13-dibutyrate (PDBu).
