Fluoroclebopride is a benzamide analog that is used in positron emission tomography (PET) applications. It binds reversibly to dopamine receptors (Kis = 0.95, 5.7, 5.46, and 144 nM for D2-like, D2(long), D3, and D4 receptors, respectively, in radioligand binding assays). It is selective for these receptors over D1, serotonin 5-HT2, and α2-adrenergic receptors (Kis = >10,000, 283, and 1,300 nM, respectively). A fluorine-18 moiety has been used to label this compound for use as a probe for studying D2/D3 receptor availability via PET in various monkey models.
