    Microfluidic radiosynthesis and biodistribution of [18F] 2-(5-fluoro-pentyl)-2-methyl malonic acid
    摘要:
    微流体技术已成为正电子发射断层扫描(PET)和单光子发射计算机断层扫描放射性标记化合物放射合成的强大工具。在这项工作中,我们利用连续流动微流体系统(Advion, Inc., USA)对马来酸衍生物[18F] 2-(5-氟戊基)-2-甲基马来酸([18F]-FPMA),即[18F]-ML-10的[18F]氟标记进行了探索,这是一种被提议作为潜在凋亡PET成像剂的放射性示踪剂。放射合成采用了一种新的磷酸酯前体进行开发。通过手动合成初步优化了氟化反应,并作为优化微流体放射合成反应参数的基础。在优化条件下,放射薄层色谱分析显示在水解和纯化之前的[18F]-氟掺入率为79%。水解后,通过C18 Sep-Pak对[18F]-FPMA进行了纯化,最终产品通过放射性高效液相色谱(radio-HPLC)进行了分析,得到了校正后的60%放射化学产率和≥98%的放射化学纯度。生物分布数据显示,注射后60分钟内血液中剩余完整[18F]-FPMA放射性不足2%,表明快速清除。大多数器官对放射性示踪剂的积累较低,放射性主要通过肾脏排除(1小时内清除率为95%)。对血浆和尿液样品的放射性HPLC分析显示,放射性示踪剂在注射后至少稳定存在60分钟。

  • Acyl-CoA:Cholesterol <i>O</i>-Acyltransferase (ACAT) Inhibitors. 2. 2-(1,3-Dioxan-2-yl)-4,5-diphenyl-1<i>H</i>-imidazoles as Potent Inhibitors of ACAT

    The second in this series of papers concerns our further investigations into the search for a potent bioavailable acyl-CoA:cholesterol O-acyltransferase (ACAT) inhibitor suitable for the treatment of atherosclerosis. The design, synthesis, and structure-activity relationship for a series of ACAT inhibitors based on the 2-(1,3-dioxan-2-yl)-4,5-diphenyl-1H-imidazole pharmacophore are described. Compounds such as 13a bearing simple alkyl or hydroxymethyl substituents at the 5-position of the 1,3-dioxane ring are potent bioavailable inhibitors of the rat hepatic microsomal enzyme in vitro (IC50 < 100 nM) but are only weak inhibitors of the human hepatic enzyme. We have found however that 1,3-dioxanes substituted at the 5-cis position with pyrazolylalkyl or aminoalkyl groups are potent inhibitors in vitro of human macrophage ACAT, the potency depending on the nature of the terminal heterocycle and the length of the alkyl chain. An ex vivo bioassay described herein demonstrates that potent inhibitors such as 13t (IC50 = 10 nM) which contain lipophilic terminal heterocycles do not appear to be systemically available. Less potent but more water soluble compounds such as 13h (IC50 = 60 nM) and 13n (IC50 = 70 nM) are absorbed following oral dosing and achieve plasma levels significantly in excess of their IC50 for ACAT inhibition. These compounds are therefore possible candidates for further investigation as oral antiatherosclerotic agents.
  • Microfluidic radiosynthesis and biodistribution of [<sup>18</sup>F] 2-(5-fluoro-pentyl)-2-methyl malonic acid

    Microfluidics technology has emerged as a powerful tool for the radiosynthesis of positron emission tomography (PET) and single-photon emission computed tomography radiolabeled compounds. In this work, we have exploited a continuous flow microfluidic system (Advion, Inc., USA) for the [18F]-fluorine radiolabeling of the malonic acid derivative, [18F] 2-(5-fluoro-pentyl)-2-methyl malonic acid ([18F]-FPMA), also known as [18F]-ML-10, a radiotracer proposed as a potential apoptosis PET imaging agent. The radiosynthesis was developed using a new tosylated precursor. Radiofluorination was initially optimized by manual synthesis and served as a basis to optimize reaction parameters for the microfluidic radiosynthesis. Under optimized conditions, radio-thin-layer chromatography analysis showed 79% [18F]-fluorine incorporation prior to hydrolysis and purification. Following hydrolysis, the [18F]-FPMA was purified by C18 Sep-Pak, and the final product was analyzed by radio-HPLC (high-performance liquid chromatography). This resulted in a decay-corrected 60% radiochemical yield and ≥98% radiochemical purity. Biodistribution data demonstrated rapid blood clearance with less than 2% of intact [18F]-FPMA radioactivity remaining in the circulation 60 min post-injection. Most organs showed low accumulation of the radiotracer, and radioactivity was predominately cleared through kidneys (95% in 1 h). Radio-HPLC analysis of plasma and urine samples showed a stable radiotracer at least up to 60 min post-injection.
