      The adenosine A<sub>2A</sub> receptor (A<sub>2A</sub>R) is regarded as a particularly appropriate target for non-dopaminergic treatment of Parkinson’s disease (PD). An increased A<sub>2A</sub>R availability has been found in the human striatum at early stages of PD and in patients with PD and dyskinesias. The aim of this small animal positron emission tomography/magnetic resonance (PET/MR) imaging ...
    • Preclinical incorporation dosimetry of [18F]FACH—A novel 18F-labeled MCT1/MCT4 lactate transporter inhibitor for imaging cancer metabolism with PET 

      Sattler, Bernhard; Kranz, Mathias; Wenzel, Barbara; Jain, Nalin T.; Moldovan, Rareş-Petru; Toussaint, Magali; Deuther-Conrad, Winnie; Ludwig, Friedrich-Alexander; Teodoro, Rodrigo; Sattler, Tatjana; Sadeghzadeh, Masoud; Sabri, Osama; Brust, Peter (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-04-26)
      Overexpression of monocarboxylate transporters (MCTs) has been shown for a variety of human cancers (e.g., colon, brain, breast, and kidney) and inhibition resulted in intracellular lactate accumulation, acidosis, and cell death. Thus, MCTs are promising targets to investigate tumor cancer metabolism with positron emission tomography (PET). Here, the organ doses (ODs) and the effective dose (ED) of ...
    • Radiosynthesis and biological investigation of a novel fluorine-18 labeled benzoimidazotriazine- based radioligand for the imaging of phosphodiesterase 2A with positron emission tomography 

      Ritawidya, Rien; Wenzel, Barbara; Teodoro, Rodrigo; Toussaint, Magali; Kranz, Mathias; Deuther-Conrad, Winnie; Dukić-Stefanović, Sladjana; Ludwig, Friedrich-Alexander; Scheunemann, Matthias; Brust, Peter (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-11-15)
      A specific radioligand for the imaging of cyclic nucleotide phosphodiesterase 2A (PDE2A) via positron emission tomography (PET) would be helpful for research on the physiology and disease-related changes in the expression of this enzyme in the brain. In this report, the radiosynthesis of a novel PDE2A radioligand and the subsequent biological evaluation were described. Our prospective compound ...
    • Synthesis and biological evaluation of a novel 18F-labeled radiotracer for PET imaging of the adenosine A2A receptor 

      Lai, Thu Hang; Toussaint, Magali; Teodoro, Rodrigo; Dukić-Stefanović, Sladjana; Kranz, Mathias; Deuther-Conrad, Winnie; Moldovan, Rareş-Petru; Brust, Peter (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-01-25)
      The adenosine A<sub>2A</sub> receptor (A<sub>2A</sub>R) has emerged as a potential non-dopaminergic target for the treatment of Parkinson’s disease and, thus, the non-invasive imaging with positron emission tomography (PET) is of utmost importance to monitor the receptor expression and occupancy during an A<sub>2A</sub>R-tailored therapy. Aiming at the development of a PET radiotracer, we herein ...
