  Synthesis and characterization of cis-4-decenoyl-CoA, 3-phenylpropionyl-CoA, and 2,6-dimethylheptanoyl-CoA

  摘要：

  The measurement of acyl-CoA dehydrogenase activities is an essential part of the investigation of patients with suspected defects in fatty acid oxidation. Multiple methods are available for the synthesis of the substrates used for measuring acyl-CoA dehydrogenase activities: however, the yields are low and the products are used without purification. In addition, the reported characterization of acyl-CoAs focuses on the CoA moiety, not on the acyl group. Here we describe the synthesis of three medium-chain acyl-CoAs from mixed anhydrides of the fatty acids using an aqueous-organic solvent mixture optimized to obtain the highest yield. First, cis-4-decenoic acid and 2,6-dimethylheptanoic acid were prepared (3-phenylpropionic acid is commercially available). These were characterized by gas chromatography/mass spectrometry (GC/MS), H-1 nuclear magnetic resonance (NMR), and C-13 NMR. Then cis-4-decenoyl-CoA, 3-phenylpropionyl-CoA, and 2,6-dimethylheptanoyl-CoA were synthesized. These were then purified by ion exchange solid-phase extraction using 2-(2-pyridyl)ethyl-functionalized silica gel, followed by reversed-phase semipreparative high-performance liquid chromatography with ultraviolet detection (HPLC-UV). The purified acyl-CoAs were characterized by analytical HPLC-UV followed by data-dependent tandem mass spectrometry (MS/MS) analysis on the largest responding MS mass (HPLC-UV-MS-MS/MS) and 13C NMR. The yields of the purified acyl-CoAs were between 75% and 78% based on coenzyme A trilithium salt (CoASH). Acyl-CoA dehydrogenase activities were measured in rat skeletal muscle mitochondria using, as substrates, the synthesized cis-4-decenoyl-CoA, 3-phenylpropionyl-CoA, and 2,6-dimethylheptanoyl-CoA. These results were compared with the results using our standard substrates butyryl-CoA, octanoyl-CoA, and palmitoyl-CoA. (C) 2010 Elsevier Inc. All rights reserved.
