  A single-mode microwave cavity was constructed for microscale reactions with consideration taken to the space limitations typical for shielded working spaces used with positron emitting radionuclides. The effect of the microwave field in this cavity on typical reaction media is demonstrated. Reaction times for radiolabelling neuroreceptor ligands with [11C]methyl iodide and [2-11C]isopropyl iodide were shown to be considerably reduced compared with the times reported in the literature for the corresponding thermal procedures.

  The peripheral benzodiazepine receptor (PBR) is widely expressed in peripheral tissues, blood cells, and in glia cells in the brain. We have previously developed two positron emission tomography ( PET) ligands, N-(2-[C-11],5-dimethoxybenzyl)-N-(5-fluoro-2-phenoxyphenyl) acetamide ([C-11]2) and its [F-18] fluoroethyl analogue ([ 18F] 6), for the current investigation of PBR in the human brain. The aim of this study was to label the potent PBR agonist N-(4-chloro-2-phenoxyphenyl)-N-(isopropoxybenzyl) acetamide (3) and its ethyl (7) and methyl (8) homologues with C-11 and to evaluate them as PET ligands for PBR with mice, rats, and monkeys. Ligands [C-11]3, [C-11]7, and [C-11]8 were synthesized by alkylation of phenol precursor 9 with 2-[2-C-11] iodopropane ([C-11]10), [1-C-11] iodoethane ([C-11]11), and [C-11] iodomethane ([ 11C]12), respectively. The alkylating agent [C-11]10 or [C-11]11 was prepared by reacting CH3MgBr with [C-11] CO2, followed by reduction with LiAlH4 and iodination with HI. In vitro quantitative autoradiography determined that 3, 7, and 8 had potent binding affinities (K-i = 0.07-0.19 nM) for PBR in the rat brain. These [C-11] ligands could pass across the blood-brain barrier and enter the rat brain (0.17-0.32% of injected dose per gram wet tissue). Ex vivo autoradiography showed that the [C-11] ligands preferably distributed in the olfactory bulb and cerebellum, two regions with richer PBR density in the rat brain. The co-injection of PBR-selective 2 reduced the [C-11] ligand binding in the two regions, suggesting that binding in the rat brain was specific to PBR. PET study determined that the [C-11] ligands preferably accumulate in the occipital cortex of the monkey brain, a region with a high density of PBR in the primate brain. Moreover, in vivo binding of the methyl homologue [C-11]8 in the monkey brain could be inhibited by PBR-selective 2 or 1, indicating that some of the [C-11]8 binding was due to PBR. Metabolite analysis demonstrated that these [C-11] ligands were metabolized by debenzylation to polar products mainly in the plasma.
