  • Synthesis, 18F-Radiolabelling and Biological Characterization of Novel Fluoroalkylated Triazine Derivatives for in Vivo Imaging of Phosphodiesterase 2A in Brain via Positron Emission Tomography

    Phosphodiesterase 2A (PDE2A) is highly and specifically expressed in particular brain regions that are affected by neurological disorders and in certain tumors. Development of a specific PDE2A radioligand would enable molecular imaging of the PDE2A protein via positron emission tomography (PET). Herein we report on the syntheses of three novel fluoroalkylated triazine derivatives (TA2–4) and on the evaluation of their effect on the enzymatic activity of human PDE2A. The most potent PDE2A inhibitors were 18F-radiolabelled ([18F]TA3 and [18F]TA4) and investigated regarding their potential as PET radioligands for imaging of PDE2A in mouse brain. In vitro autoradiography on rat brain displayed region-specific distribution of [18F]TA3 and [18F]TA4, which is consistent with the expression pattern of PDE2A protein. Metabolism studies of both [18F]TA3 and [18F]TA4 in mice showed a significant accumulation of two major radiometabolites of each radioligand in brain as investigated by micellar radio-chromatography. Small-animal PET/MR studies in mice using [18F]TA3 revealed a constantly increasing uptake of activity in the non-target region cerebellum, which may be caused by the accumulation of brain penetrating radiometabolites. Hence, [18F]TA3 and [18F]TA4 are exclusively suitable for in vitro investigation of PDE2A. Nevertheless, further structural modification of these promising radioligands might result in metabolically stable derivatives.
    磷酸二酯酶2A(PDE2A)在特定的神经疾病受影响的脑区和某些肿瘤中高度特异性表达。开发一种特定的PDE2A放射配体将使得通过正电子发射断层扫描(PET)对PDE2A蛋白进行分子成像成为可能。在此,我们报告了三种新型氟烷基化三嗪衍生物(TA2–4)的合成及其对人类PDE2A酶活性的影响评估。最有效的PDE2A抑制剂为18F标记的([18F]TA3和[18F]TA4),并对其作为PET放射配体在小鼠脑中成像PDE2A的潜力进行了研究。对大鼠脑进行的体外自放射影像显示,[18F]TA3和[18F]TA4具有区域特异性分布,这与PDE2A蛋白的表达模式一致。对小鼠中[18F]TA3和[18F]TA4的代谢研究显示,每种放射配体在脑中均显著积累了两种主要放射代谢物,且通过胶束放射色谱法进行了探讨。使用[18F]TA3的鼠类PET/MR研究显示,在非靶向区域小脑中活性不断增加的摄取可能是由能穿透脑部的放射代谢物的积累引起的。因此,[18F]TA3和[18F]TA4特别适合于PDE2A的体外研究。然而,进一步对这些有前景的放射配体进行结构改造可能会导致代谢稳定的衍生物。

    The identification of highly potent and orally active phenylpyrazines for the inhibition of PDE10A is reported. The new analogues exhibit subnanomolar potency for PDE10A, demonstrate high selectivity against all other members of the PDE family, and show desired druglike properties. Employing structure-based drug design approaches, we methodically explored two key regions of the binding pocket of the PDE10A enzyme to alter the planarity of the parent compound I and optimize its affinity for PDE10A. Bulky substituents at the C9 position led to elimination of the mutagenicity of 1, while a crucial hydrogen bond interaction with Glu716 markedly enhanced its potency and selectivity. A systematic assessment of the ADME and PK properties of the new analogues led to druglike development candidates. One of the more potent compounds, 96, displayed an IC50 for PDE10A of 0.7 nM and was active in predictive antipsychotic animal models.
