  Modulation of Ceramide-Activated Protein Phosphatase 2A Activity by Low Molecular Weight Aromatic Compounds

  摘要：

  Protein phosphatase 2A (PP2A) is one of the most important and abundant serine/threonine phosphatases in mammalian tissues and plays a role in gene expression, cell division, and signal transduction. PP2A is activated by ceramide, which is produced by the hydrolysis of membrane sphingomyelin in response to a variety of stress-related stimuli. To further study the role of ceramide-mediated signal transduction in cellular processes such as senescence and apoptosis, we designed and synthesized a series of low molecular weight aromatic compounds, mainly of the isoquinolone and tetralone classes, and evaluated their ability to inhibit enzymes known to be activated by ceramide. Those enzymes studied were ceramide-activated protein kinase, protein kinase C zeta and PP2A. Of these, only PP2A was found re, be inhibited. A few of the compounds inhibited both ceramide-activated as well as basal PP2A activity. In addition, several of the compounds activated PP2A by up to 300% above basal enzyme activity, but only in the presence of ceramide. Thus, modulation (both inhibition and activation) of the catatylic activity of ceramide-activated PP2A is demonstrated by certain low molecular weight aromatic compounds.

  Novel substituted 6,7-dimethoxy-1-tetralones and 5,6-dimethoxy-1-indanones have been synthesized and evaluated for their cytotoxicity. Compounds with 3'-lipophilic. 3',5'-dilipophilic, or 3',5'-dilipophilic-4'-hydrophilic substituents on (E)-2-benzylidene moiety showed highly cytotoxic effects. The unique structure of 42 possibly matches the pharmacophore features for these cytotoxic compounds. (C) 2000 Elsevier Science Ltd. All rights reserved.
