  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).
