 note = {Derivatives of 9,10-ethanobenzo[b]quinolizinium are potent antagonists of the TCP-site of the NMDA receptor.  Two fluoroethyl-substituted analogues were labelled with fluorine-18 by displacement of the tosylate with [18F]fluoride, followed by a Diels-Alder reaction.  A methoxy-substituted analogue labelled with carbon-11 was obtained by O-methylation of the corresponding hydroxy precursor with [11C]iodomethane.  In biodistribution studies in mice with these three radioligands, it was found that they have little ability to penetrate the blood-brain barrier.},
