  Synthesis and Characterization of New Photolabile Phorbol Esters for Affinity Labeling of Protein Kinase C

  摘要：

  Three new photolabile phorbol esters (3, 6, and 9) with a diazoacetyl group at positions 3, 12, and 13, respectively, have been synthesized from phorbol (1a) and found to bind with significant affinity to the peptide (peptide C) incorporating the phorbol ester-binding domain of protein kinase C. As required for its use as a protein kinase C receptor probe, the solution photochemistry of 3 led predominantly to insertion products. Tritium labeling of these probes at C-20 was accomplished by oxidation with activated manganese dioxide to the C-20 aldehyde and subsequent H-3-labeled sodium borohydride reduction. Initial affinity labeling studies showed that probes 6 and 9 labeled peptide C, suggesting that the introduction of a photolabile group into position 12 or 13 of the phorbol esters could be used to identify the structural features of PKC involved in its binding to activators.

  Photoaffinity labeling of PKC with a phorbol derivative: Importance of the 13-acyl group in phorbol ester-PKC interaction

  摘要：

  We report the design and synthesis of a novel photoaffinity ligand, phorbol 12-(1-pyrenebutyrate) 13-diazoacetate (PPDA, 6). This photolabile phorbol derivative labeled with tritium was used for photocrosslinking experiments with a sample of PKC partially purified from rat brain, and specific binding of 6 to PKC was observed.

  Photoaffinity probes PPDA and PPTD, which have diazoacetyl and trifluorodiazopropionyl group at C-13 position in phorbol, respectively, were synthesized. Photoaffinity labeling of protein kinase C isozymes by both the probes resulted in specific cross-linking. (C) 1998 Elsevier Science Ltd. All rights reserved.
