摘要

The neurochemical profile of a new compound, Lu 19-005 [(+/-)trans-3-(3,4-dichlorophenyl)-N-methyl-1-indanamine hydrochloride], has been investigated. Lu 19-005 is a potent inhibitor of the synaptosomal uptake of 3,4-dihydroxyphenylethylamine (dopamine, DA), noradrenaline (NA), and 5-hydroxytryptamine (5-HT, serotonin). In this respect it resembles diclofensine, whereas compounds such as GBR 13.069 and bupropion are more selective DA-uptake inhibitors. Although Lu 19-005 releases DA in in higher concentrations it must be considered as an uptake inhibitor, as the accumulation of DA is inhibited in much lower concentrations. Lu 19-005 attenuates the DA and NA depletion caused by 6-hydroxydopamine in mouse brain. These properties confirm the DA- and NA-uptake-inhibitory properties of the compound. In receptor-binding models and functional in vitro tests Lu 19-005 is devoid of dopaminergic-, serotonergic-, noradrenergic-, histaminergic-, and cholinergic-inhibiting properties. Since DA, NA, and 5-HT seem to be involved in depression, the profile of Lu 19-005--with equally potent activity on the three neuronal systems--makes it an interesting experimental tool and a potential new antidepressant agent.
