  Synthesis and evaluation of [18F]fluororasagiline, a novel positron emission tomography (PET) radioligand for monoamine oxidase B (MAO-B)

  摘要：

  The aim of this study was to synthesize and evaluate a novel fluorine-18 labeled analogue of rasagiline (6) as a PET radioligand for monoamine oxidase B (MAO-B). The corresponding non-radioactive fluorine-19 ligand, (1S,2S)-2-fluoro-N-(prop-2-yn-1-yl)indan-1-amine (4), was characterized in in vitro assays.The precursor compound (3aS,8aR)-3-(prop-2-yn-1-yl)-3,3a,8,8a-tetrahydroindeno[1,2-d][1,2,3]oxa-thiazole 2,2-dioxide (3) and reference standard 4 were synthesized in multi-step syntheses. Recombinant human MAO-B and MAO-A enzyme preparations were used in order to determine IC50 values for compound 4 by use of an enzymatic assay employing kynuramine as substrate. Radiolabeling was accomplished by a two-step synthesis, compromising a nucleophilic substitution followed by hydrolysis of the sulphamidate group. Human whole hemisphere autoradiography (ARG) was performed with [F-18]fluororasagiline. Blocking experiments with pirlindole (MAO-A), L-deprenyl and rasagiline (MAO-B) were conducted to demonstrate the specificity of the binding. A positron emission tomography (PET) study was carried out in a cynomolgus monkey where time activity curves for whole brain and regions with high and low MAO-B activity were recorded. Radiometabolites were measured in monkey plasma using gradient HPLC.Compound 4 inhibited MAO-B with an IC50 of 27 nM and MAO-A with an IC50 of 2.3 mu M. Radiolabeling of precursor 3 and subsequent hydrolysis of the protecting group towards (1S,2S)-2-[F-18]fluoro-N-(prop-2-yn-1-yl)indan-1-amine (6) was successfully accomplished with an radiochemical yield of 40-70%, a radiochemical purity higher than 99% and a specific radioactivity higher than 200 GBq/mu mol. ARG demonstrated selective binding for [F-18]fluororasagiline (6) to MAO-B containing brain regions, for example, striatum. The initial uptake in the monkey brain was 250% SUV at 4 min post injection. The highest amounts of radioactivity were observed in the striatum and thalamus as expected whereas in the cortex and cerebellum lower levels were observed. Metabolite studies demonstrated 30% unchanged radioligand at 90 min post injection.Our investigations demonstrated that the new ligand [F-18]fluororasagiline (6) binds specifically to MAO-B in vitro and has a MAO-B specific binding pattern in vivo. Thus, it could serve as a novel potential candidate for human PET studies. (C) 2012 Elsevier Ltd. All rights reserved.

  intramolecular CH amination and aziridination reactions were developed. Sulfamate esters were converted to oxathiazinanes by using CoPd(OAc)4 as catalyst and PhI(OAc)2 as oxidant. The mutual presence of both Co and Pd is crucial for the catalytic activity. This combination of two metals with simple acetate ligands provides an economical alternative to the Rh‐catalyzed insertion of nitrenoids into CH bonds
