Evaluation of [11C]Cimbi-36 as an Agonist PET Radioligand for Imaging of 5-HT2A Receptors

Summary

The purpose of this project was to introduce the recently developed positron emission tomography (PET) tracer \[11C\]Cimbi-36 for use in clinical studies and to investigate the ability of the tracer to quantify the 5-HT2A receptor in the human brain. As a receptor agonist, \[11C\]Cimbi-36 binding will provide a more functional picture of 5-HT2A receptors, while this binding is thought to be correlated to brain serotonin levels. Both measurement of signaling through the 5-HT2A receptor and measurement of serotonin levels in vivo would have great scientific relevance for significant diseases such as depression and schizophrenia.
