In the search for a novel serotonin 7 (5-HT7) receptor PET radioligand we synthesized and evaluated a new series of biphenylpiperazine derivatives in vitro. Among the studied compounds, (R)-1-[4-[2-(4-methoxyphenyl)phenyl]piperazin-1-yl]-3-(2-pyrazinyloxy)-2-propanol, showed the best combination of affinity, selectivity, and lipophilicity, and was thus chosen for carbon-11 labeling and evaluation in pigs. After i.v. injection, compound I entered the pig brain and displayed reversible tracer kinetics. Pretreatment with the 5-HT7 receptor selective antagonist SB-269970 resulted in limited decrease in the binding of I, suggesting that this radioligand is not optimal for imaging the brain 5-HT7 receptor in vivo but it may serve as a lead compound for the design of novel 5-HT7 receptor PET radioligands.
