A series of fluoro-substituted analogs structurally derived from the aminomethyl-substituted pyrazolo[1,5-a]pyridine lead compounds9(FAUC 113) and10(FAUC 213) were synthesized and evaluated as high-affinity D4receptor (D4R) ligands (3a−3h,Ki= 1.3–28 nM). Thepara-fluoroethoxy-substituted derivatives3fand3hrevealed an outstanding D4subtype selectivity of more than 3 orders of magnitude over both congeners D2and D3combined with inverse agonism at D4R. The corresponding18F-labeled radioligands revealed high serum stability in vitro and logPvalues of 2–3. In vitro rat brain autoradiography showed specific binding of[18F]3hin distinct brain regions, including the gyrus dentate of the hippocampus, that were inhibited by both eticlopride (65–80%) and the selective D4R antagonist10(78–93%). The observed binding pattern was mainly consistent with the known D4R distribution in the rat brain. Thus,[18F]3h(FAUC F41) represents a potential radioligand for studying the D4R in vivo by positron emission tomography (PET).
