  Synthesis and Evaluation in Monkey of [¹⁸F]4-Fluoro-N-methyl-N-(4-(6-(methylamino)pyrimidin-4-yl)thiazol-2-yl)benzamide ([¹⁸F]FIMX): A Promising Radioligand for PET Imaging of Brain Metabotropic Glutamate Receptor 1 (mGluR1)

  摘要：

  We sought to develop a PET radioligand that would be useful for imaging human brain metabotropic subtype 1 receptors (mGluR1) in neuropsychiatric disorders and in drug development. 4-Fluoro-N-methyl-N-(4-(6(methylamino)pyrimidin-4-yOthiazol-2-ylbenzamide (FIMX, 11) was identified as having favorable properties for development as a PET radioligand. We developed a method for preparing [F-18]11 in useful radiochemical yield and in high specific activity from [18F]fluoride ion and an N-Boc-protected (phenyl)aryliodonium salt precursor (15). In baseline experiments in rhesus monkey, [F-18 ]11 gave high brain radioactivity uptake, reflecting the expected distribution of mGluR1 with notably high uptake in cerebellum, which became 47% lower by 120 min after radioligand injection. Pharmacological challenges demonstrated that a very high proportion of the radioactivity in monkey brain was bound specifically and reversibly to mGluRl. [F-18]11 is concluded to be an effective PET radioligand for imaging mGluR1 in monkey brain and therefore merits further evaluation in human subjects.

  4-卤代-N- [4- [6-（异丙基氨基）嘧啶-4-基] -1,3-噻唑-2-基] -N- [ 11 C]甲基苯甲酰胺的合成和评价用于代谢型谷氨酸1的成像黑色素瘤受体

  摘要：

  代谢型谷氨酸1（mGlu1）受体不仅存在于大脑中，而且还存在于黑色素瘤和乳腺癌中。mGlu1是基于分子影像学的黑色素瘤诊断和治疗的有希望的靶标，因为它的过度表达会诱导黑色素细胞癌变。在这里，我们开发了三种PET示踪剂：4-卤代-N- [4- [6-（异丙基氨基）嘧啶-4-基] -1,3-噻唑-2-基] -N- [ 11 C]甲基苯甲酰胺（[ 11 C] 4 – 6），在目标肿瘤中表现出较高的摄取，在非目标脑组织中表现出减少的摄取。体外结合试验表明结合亲和力为4 – 6（K i（22–143 nM）用于mGlu1受体。在植入了B16F10黑色素瘤细胞的小鼠中进行的体内生物分布研究证实，肿瘤中放射性的摄取较高，而血液，皮肤和肌肉的摄取较低。使用mGlu1选择性配体抑制mGlu1受体导致肿瘤中放射性吸收的减少。[ 11 C] 6在肿瘤和非靶组织之间显示出最高的摄取率，可能被证明可作为黑色素瘤中mGlu1成像的PET示踪剂。

  Molecules labeled with fluorine-18 (18F) are used in positron emission tomography to visualize, characterize and measure biological processes in the body. Despite recent advances in the incorporation of 18F onto arenes, the development of general and efficient approaches to label radioligands necessary for drug discovery programs remains a significant task. This full account describes a derisking approach

  Three novel 4-substituted benzamides have been synthesized as potential ligands for the positron emission tomography (PET) imaging of metabotropic glutamate 1 (mGlu1) receptor in the brain. Of these compounds, N-(4-(6-(isopropylamino)pyrimidin-4-yl)-1,3-thiazol-2-yl)-N,4-dimethylbenzamide (4) exhibited the highest binding affinity (K-i = 13.6 nM) for mGlu1 and was subsequently labeled with carbon-11. In vitro autoradiography using rat brain sections showed that [C-11]4 binding was consistent with the distribution of mGlu1, with high specific binding in the cerebellum and thalamus. PET studies with [C-11]4 in monkey showed a high brain uptake and a kinetic profile suitable for quantitative analysis. Pretreatment with a mGlu1-selective ligand 16 largely decreased the brain uptake, indicating high in vivo specific binding of [C-11]4 to mGlu1. In metabolite analysis, only unchanged [C-11]4 was found in the brain. [C-11]4 is a useful PET ligand for the imaging and quantitative analysis of mGlu1 in monkey brain and merits further evaluation in humans.
