  [F-18]labeling of 1,2-diacylglycerols

  摘要：

  We have developed two kinds of [F-18]labeled 1,2-diacylglycerols (1,2-DAGs) such as 1-(omega-[F-18]fluoroacyl)-2-acylglycerols (1*,2-[F-18]FDAGs) and 2-(omega-[F-18]fluoroacyl)-1-acylglycerols (1,2*-[F-18]FDAGs) for imaging receptor-mediated phosphatidyl-inositol (PI) turnover responses by positron emission tomography (PET). The 1*,2-[F-18]FDAGs were synthesized by the reaction of 2-monoacyl glycerols with omega-[F-18]fluoroacyl chlorides (method A) and 1-(16-[F-18]fluoro palmitoyl)-2-palmitoylglycerol (1*,2-[F-18]FDAG(C16,C16)) and 1-(8-[F-18]fluoro octanoyl)-2-palmitoylglycerol (1*,2-[F-18]FDAG(C8,C16)) were synthesized using method A. However, during the synthesis of 1,2*-[F-18]FDAGs, we adopted the hydrogenolysis to remove a benzyl group from 3-O-benzyl-2-(omega-[F-18]fluoroacyl)-1-acylglycerol, which was synthesized by the nucleophilic exchange reaction of 3-O-benzyl-2-(omega-bromoacyl)-1-acylglycerol with [F-18]F- (method B) and 2-(16-[F-18]fluoropalmitoyl)-1-palmitoylglycerol (1,2*-[F-18]FDAG(C16,C16)) and [F-18]fluorooctanoyl)-1-palmitoylglycerol (1,2*-[F-18]FDAG(C16,C8)) were produced using method B. The purified 1*,2-[F-18]FDAGs were obtained in radiochemical yields of 8-35 % (based on [F-18]F-) with radiochemical purities of > 97 % and the purified 1,2*-[F-18]FDAGs were in radiochemical yields of 5-15 % with radiochemical purities of > 95 %. The total synthesis time from the start of the reactive [F-18]F- production, including HPLC purification, was 100 - 135 min (method A) and 115 - 175 min (method B), respectively. It has already been used for more than 100 preparations of 1*,2-[F-18]FDAG(C16,C16), 1*,2-[F-18]FDAG(C8, C16), and 1,2*-[F-18]FDAG(C16,C16), 1,2*-[F-18]FDAG(C16,C8) for animal studies.
