A New Class of Fluorinated A2A Adenosine Receptor Agonist with Application to Last‐Step Enzymatic [18F]Fluorination for PET Imaging
Abstract
The A 2A adenosine receptor belongs to a family of G‐coupled protein receptors that have been subjected to extensive investigation over the last few decades. Due to their prominent role in the biological functions of the heart, lungs, CNS and brain, they have become a target for the treatment of illnesses ranging from cancer immunotherapy to Parkinson's disease. The imaging of such receptors by using positron emission tomography (PET) has also been of interest, potentially providing a valuable tool for analysing and diagnosing various myocardial and neurodegenerative disorders, as well as offering support to drug discovery trials. Reported herein are the design, synthesis and evaluation of two new 5′‐fluorodeoxy‐adenosine (FDA)‐based receptor agonists (FDA‐PP1 and FDA‐PP2), each substituted at the C‐2 position with a terminally functionalised ethynyl unit. The structures enable a synthesis of 18 F‐labelled analogues by direct, last‐step radiosynthesis from chlorinated precursors using the fluorinase enzyme (5′‐fluoro‐5′‐deoxyadenosine synthase), which catalyses a transhalogenation reaction. This delivers a new class of A 2A adenosine receptor agonist that can be directly radiolabelled for exploration in PET studies.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
