| Abstract: | 5-Methyl-6-nitroquipazine, a novel analogue of the potent and selective serotonin transporter inhibitor 6-nitroquipazine was synthesized and radiolabeled with tritium and the positron emitter carbon-11. 3H]5-methyl-6-nitroquipazine was found to have a Kd=51±7 pM. The high affinity and the facile labeling of 11C]5-methyl-6-nitroquipazine makes it a promising radioligand for visualization of the serotonin transporter with positron emission tomography. |
