Imaging of adenosine A1 receptors in the human brain by positron emission tomography with [11C]MPDX.

چکیده
We report the first clinical PET study using [1-methyl-11C]8-dicyclopropylmethyl-1-methyl-3-propylxanthine ([11C]MPDX) for imaging adenosine A1 receptors in the human brain. The binding of [11C]MPDX evaluated quantitatively as the distribution volume by a graphical analysis was high in the striatum and thalamus, and low in the cerebellum. The distribution pattern of [11C]MPDX was coincident with that of adenosine A1 receptors in vitro reported previously, and was different from those of blood flow and [18F]FDG. The [11C]MPDX PET has the potential for mapping adenosine A1 receptors in the human brain.

Preclinical studies on [11C]MPDX for mapping adenosine A1 receptors by positron emission tomography.
In previous in vivo studies with mice, rats and cats, we have demonstrated that [11C]MPDX ([1-methyl-11C]8-dicyclopropylmethyl-1-methyl-3-propylxanthine) is a potential radioligand for mapping adenosine A1 receptors of the brain by positron emission tomography (PET). In the present study, we performed a preclinical study. The radiation absorbed-dose by [11C]MPDX in humans estimated from the tis...
متن کاملImproved synthesis of [11C]SA4503, [11C]MPDX and [11C]TMSX by use of [11C]methyl triflate.
Recently we have clinically used three new radioligands, [11C]SA4503, [11C]MPDX, and [11C]TMSX, for mapping sigma1, adenosine A1, and adenosine A2A receptors, respectively, in the human brain by positron emission tomography. These radioligands are synthesized by methylation of the respective demethyl precursor with [11C]methyl iodide. Here we demonstrate the improved syntheses of these compound...
متن کاملAge-Related Decrease in Male Extra-Striatal Adenosine A1 Receptors Measured Using 11C-MPDX PET
Adenosine A1 receptors (A1Rs) are widely distributed throughout the entire human brain, while adenosine A2A receptors (A2ARs) are present in dopamine-rich areas of the brain, such as the basal ganglia. A past study using autoradiography reported a reduced binding ability of A1R in the striatum of old rats. We developed positron emission tomography (PET) ligands for mapping the adenosine recepto...
متن کاملAdenosine A1 receptor mapping of the human brain by PET with 8-dicyclopropylmethyl-1-11C-methyl-3-propylxanthine.
UNLABELLED Adenosine is an endogenous modulator of synaptic functions in the central nervous system. To investigate the physiologic and pathologic roles of the adenosine receptors in the human brain, PET is a powerful in vivo technique. In this study, we quantitatively evaluated the distribution of a major subtype A(1) adenosine receptor in the human brain by PET with a newly developed radiolig...

In previous in vivo studies with mice, rats, cats and monkeys, we have demonstrated that [7-methyl-11C]-(E)-8-(3,4,5-trimethoxystyryl)- 1,3,7-trimethylxanthine ([11C]TMSX) is a potential radioligand for mapping adenosine A2A receptors of the brain by positron emission tomography (PET). In the present study, we studied the potential of [11C]TMSX for myocardial imaging. Uptake of radioactivity by...
