6-Nitroquipazine is a very potent and selective inhibitor of neuronal 5-hydroxytryptamine (5-HT; serotonin) uptake. We have characterized the specific binding of [3H]6-nitroquipazine to rat brain membranes at 22 degrees C. The present results indicate the presence of a single saturable

Direct counting of axon terminals (varicosities) labeled by uptake/storage of a tritiated monoamine provides a means to test radioligands of the corresponding membrane transporter as quantitative markers of regional monoamine innervation density in brain tissue. In autoradiographs from alternate rat

Five C2'-substituted 6-nitroquipazine (6-NQ) derivatives were prepared and evaluated in terms of their biological abilities (K(i)) to displace [(3)H]citalopram binding to serotonin transporter. The relationship between their structure and biological activities revealed that shorter alkyl groups tend to possess higher

3-(3-[18F]Fluoropropyl)-6-nitroquipazine ([18F]FPNQ) as a 5-HT transporter imaging agents was designed, synthesized, and evaluated. FPNQ was selected due to its potent in vitro biological activity (K(i)=0.32 nM) in rat brain cortical membranes. The 18F-labeled FPNQ was prepared by reaction of the

Discs of pig retina were preincubated with 3H-noradrenaline, 3H-dopamine or 3H-serotonin and then superfused. Electrical field stimulation increased the outflow of tritium from discs preincubated with 3H-noradrenaline or 3H-dopamine, but no from discs preincubated with 3H-serotonin. The tritium content at
