ACTIVE MOIETY
Official Title: Evaluation of (11C)Cimbi-36 as an Agonist PET Radioligand for Imaging of 5-HT2A Receptors Purpose: The serotonin 2A (5-HT2A) receptor is the most abundant excitatory serotonin (5-HT, 5-hydroxytryptamine) receptor in the human brain, and multiple positron emission tomography (PET) studies have investigated the 5-HT2A receptors in the human brain using antagonist radioligands. However, the currently available antagonist PET radioligands bind the total pool of 5-HT2A receptor receptors whereas a 5-HT2A receptor agonist binds the high-affinity subgroup of the receptors which are also G-protein coupled, and thus hypothesized to be the functional relevant population of receptors. At the Center for Integrated Molecular Brain Imaging (CIMBI), a novel agonist PET radioligands for brain imaging of 5-HT2A receptors was recently validated in animals (Ettrup et al. 2011, EJNMMI). In the human brain, (11C)Cimbi-36 was validated as a selective 5-HT2A receptor agonist PET radioligand through a blocking study with the 5-HT2A receptor antagonist pharmaceutical ketanserin. In this validation study, the biodistribution and kinetic modelling of (11C)Cimbi-36 binding in the human brain was also validated. With these studies, investigators will test the most promising of these, (11C)Cimbi-36, in clinical trials, where it will provide a novel method for detecting dysfunction in the 5-HT system.
