Mefway (18F)
Mefway (18F) is a radioligand used in positron emission tomography (PET) imaging. It is a fluorine-18 labeled analog of WAY-100635, a potent and selective antagonist of the serotonin 5-HT1A receptor. Mefway (18F) is used to visualize and quantify the distribution of 5-HT1A receptors in the human brain.
History
Mefway (18F) was first synthesized in the early 2000s as part of a broader effort to develop new radioligands for PET imaging of the serotonin system. The development of Mefway (18F) was motivated by the need for a radioligand with improved properties compared to existing 5-HT1A receptor PET tracers, such as [[11C]WAY-100635]].
Chemistry
Mefway (18F) is a fluorinated analog of WAY-100635. The fluorine-18 isotope is incorporated into the molecule via a nucleophilic substitution reaction. The resulting compound is a potent and selective antagonist of the 5-HT1A receptor, with a high affinity for this receptor subtype.
Pharmacology
Mefway (18F) binds selectively to the 5-HT1A receptor, allowing for the visualization and quantification of this receptor subtype in the brain. The binding of Mefway (18F) to the 5-HT1A receptor is reversible, which is a desirable property for a PET radioligand.
Clinical Use
Mefway (18F) is used in PET imaging to study the distribution and density of 5-HT1A receptors in the human brain. This can be useful in research and clinical settings, for example, to investigate the role of the serotonin system in psychiatric and neurological disorders.
