  N-(5-Fluoro-2-phenoxyphenyl)-N-(2-[¹³¹I]iodo-5-methoxybenzyl)acetamide:  A Potent Iodinated Radioligand for the Peripheral-type Benzodiazepine Receptor in Brain

  摘要：

  To image the peripheral-type benzodiazepine receptor (PBR) in vivo, we previously developed two positron emission tomography (PET) ligands, N-(2-[C-11],5-dimethoxybenzyl)-N-(5-fluoro-2-phenoxyphenyl)acetamide ([C-11]1a) and its [F-18]fluoroethyl analogue ([F-18]1b), for the investigation of PBR in the living human brain. This time, using 1a as a leading compound, we designed two novel iodinated analogues, N-(5-fluoro-2-phenoxyphenyl)-N-(2-iodo-5-methoxybenzyl)acetamide (3a) and N-(2,5-dimethoxybenzyl)-N-(5-iodo-2-phenoxyphenyl)acetamide (3b) for the PBR imaging. Ligands 3 were synthesized by the iodination of tributystannyl precursors 10. Radiolabeling for 3 with I-131 was carried out by the reaction of 10 with [I-131]NaI using H2O2 as an oxidizing agent. In vitro competition experiments determined that 3a exhibited both high affinity and selectivity for PBR (IC50: 7.8 nM) vs CBR (> 1 mu M). Biodistribution study in mice determined that [I-131]3a had a high radioactivity level (1.69% dose/g) in the brain, and its distribution pattern in the brain was consistent with the known distribution of PBR in rodents. Ex vivo autoradiography of the rat brain gave visual evidence that [I-131]3a was a potent and specific radioligand for PBR.

• Synthesis ofN-(2,5-dimethoxybenzyl)-N-(5-fluoro-2-phenoxyphenyl)[carbonyl-11C]acetamide ([carbonyl-11C]DAA1106) and analogues using [11C]carbon monoxide and palladium(0) complex

  日期：2007.11

  N-(2,5-Dimethoxybenzyl)-N-(5-fluoro-2-phenoxyphenyl)acetamide (DAA1106), a potent and selective ligand for peripheral benzodiazepine receptor, and eight structurally related analogues were labelled with 11C at the carbonyl position using a low concentration of [11C]carbon monoxide and the micro-autoclave technique. A combinatorial approach was applied to synthesize the analogues using similar reaction conditions. Palladium-mediated carbonylation using tetrakis(triphenylphosphine)palladium, various amines and methyl iodide or iodobenzene was employed in the synthesis. The 11C-labelled products were obtained with 10–55% decay-corrected radiochemical yields and the final product was more than 97% pure in all cases. Specific radioactivity was determined for the compound [carbonyl-11C]DAA1106 using a single experiment and a 10-µA h bombardment. The specific radioactivity, measured 36 min after end of bombardment, was 455 GBq/µmol. Synthetic routes to the precursors and reference compounds were also developed. The presented approach is a novel method for the synthesis of [carbonyl-11C]DAA1106 and its analogues, and allows the formation of a library of 11C-labelled DAA1106 analogues which can be used to optimize the performance as a potential positron emission tomography tracer.
