Positron emission tomography (PET) utilises positron emitting radiopharmaceuticals in the study of metabolic and physiological processes. Production of the positron emitting radionuclide by a cyclotron followed by its incorporation into a molecule of a physiologically active compound using the appropriate radiochemical techniques is the starting point for any PET study.After the injection of the labelled tracer, the space- and time-resolved image of positron annihilations is detected externally using rings of coincidence detectors placed around the subject (a PET scanner). PET investigations using 2-[18F]fluoro-2-deoxy-D-glucose (FDG) become available in a large number of hospitals worldwide. Specific tracers are being developed mostly for oncological, neurological and cardiological applications and for drug design.
DFT modelling of conformational behaviour of FDG and its interactions with water molecules attracted little attention. [i] , [ii] A Web of Science search with the keywords "positron emission tomography" and "molecular modelling" returned one result. [iii] Replacement of "molecular modelling" for "DFT" led to five meaningful publications. Placing of "MP2" instead of "DFT" again led to just one result.ii In this talk I wish to highlight perspectives of molecular modelling for the development of PET analogues of large aromatic amino acids for oncological and neurological applications.
