Synthesis, biological activity, and structure–selectivity relationship (SSR) studies of a novel series of potential dopamine D3 receptor radioligands as imaging agents for positron emission tomography (PET) are reported. Considering a structurally diverse library of D3 ligands, SSR studies were performed for a new series of fluorinated pyridinylphenyl amides using CoMFA and CoMSIA methods. The in vitro D3 affinities of the predicted series of biphenyl amide ligands9 a–drevealed single‐digit to sub‐nanomolar potencies (Ki=0.52–1.6 nM), displaying excellent D3 selectivity over the D2 subtype of 110‐ to 210‐fold for the test compounds9 a–c. Radiofluorination by nucleophilic substitution of Br or NO2by18F led to radiochemical yields of 66–92 % for [18F]9 a–d. However, the specific activities of [18F]9 band [18F]9 dwere insufficient, rendering their use for in vivo studies impossible. Biodistribution studies of [18F]9 aand [18F]9 cusing rat brain autoradiography revealed accumulation in the ventricles, thus indicating insufficient biokinetic properties of [18F]9 aand [18F]9 cfor D3 receptor imaging in vivo.
